5.4 Redshift Determination and Source Classification

From the 477 spectra collected, we have obtained spectroscopic redshifts for 438 of the 1034 2 – 10 keV sources from Paper I. We do not include spectroscopic followup of any of the soft-only sources presented in the Appendix of Paper I, as the goal of our program has

always been to focus our telescope and analysis time on the hard-band populations.

To obtain source redshifts, we measure the observed line centers and average the cor- responding redshifts. When possible, we avoid using broad lines in determining source redshifts; in particular, we exclude lines such as CIVλ1549 that are known to be system- atically blueshifted from the object’s systemic redshift (Vanden Berk et al. 2001). When possible we measure the narrow oxygen lines, [OII]λ3727 or [OIII]λ5007, although determining source redshifts to<1% is not essential for our scientific goals. When our emission or absorption line identification is tentative, we flag the source in the catalog. This occurs in∼5% of the cases—typically faint sources which lack bright, high-ionization lines.

When a source has a reasonable signal yet lacks identifiable spectral features, we include it in the source catalog and document the wavelength range observed. These sources mainly show faint, power-law-like continua, although in a few cases the signal to noise is quite high.

Sources so faint that the continuum is not clearly detected are excluded from the catalog.

In addition to determining redshifts, our spectroscopic data allow us to group the sources into broad classes based on their spectral features. This classification is independent of the sources’ X-ray properties. The broad goal of this classification is to separate sources that appear to have normal galaxy spectra from those that exhibit features characteristic of an active nucleus—high-ionization lines that are either broad or narrow. In detail, our spectral classification is as follows:

• Broad-Lined AGN (BLAGN):We classify sources as BLAGN if they have broad (FWHM ∼> 2000 km s⁻¹) emission lines such as Lyα, C IV λ1549, C III] λ1909, Mg II λ2800, [Ne V] λλ3346, 3426, Hβ, Hα. These sources include Type 1 Seyferts and QSOs, which in the unified theory (Antonucci 1993) are objects viewed with the obscuring torus face on and the central nuclear region unobscured. An example of a typical BLAGN optical spectrum is shown in Figure 5.2.

• Narrow-Lined AGN (NLAGN):We classify sources as NLAGN if they have high- ionization emission lines similar to those seen in BLAGN, but with FWHM∼<2000 km s⁻¹. Typical high-ionization lines indicating the presence of an AGN are CIVλ1549, C III] λ1909, and [Ne V] λ3426. Low-ionization lines such as Lyα, Mg II λ2800, Hβ, Hα, etc., will usually also be present given appropriate wavelength coverage, but are not alone sufficient to classify a source as a NLAGN. Figure 5.3 provides three

This spectrum was obtained with LRIS, using a 5600 ˚A dichroic. The absorptions at 7600 ˚A (A-band) and 6850 ˚A (B-band) are telluric in nature

examples. These sources are the obscured AGN in the unified model (Antonucci 1993), viewed edge-on with an obscured view of the nucleus. In earlier studies of the lower-z universe, line ratios such as [OIII] λ5007/Hβ, [NII]λ6583/Hα, etc., have been used to differentiate spectra that show narrow lines due to ionization by hot stars from spectra that show narrow lines due to an active nucleus (e.g.,Veilleux & Osterbrock 1987). We do not measure such line ratios or apply them in our classification. Our sources span a large range in redshift and most are faint in the optical. Thus the emitted-frame spectral coverage varies greatly from source to source, and our spectral and spatial resolutions are too low to deblend and measure ratios accurately. There may be a handful of sources classifed as ELG (see below) that could be reclassifed as AGN-dominated based solely on their line ratios in our data, but this number of sources is expected to be small (<10).

• Emission-Line Galaxies (ELG):Extragalactic sources with narrow emission lines, but with no obvious AGN features in their optical spectra (e.g., high-ionization and/or broad lines) are classified as ELG. The emission lines in these spectra indicate that the ionization mechanism dominating the optical light we receive is from hot stars, not from a hard, power-law source. This classification does not rule out the presence of an underlying active nucleus; indeed, we believe the X-ray emission from the vast

Figure 5.3 Example spectra of NLAGN atz= 0.5, z= 1.2, andz= 2.4. Note the narrow, high-ionization lines. For the lowest-z source (top panel) the classification depends on the [Ne V] λ3426 detection, while the higher-z sources have narrow, high-ionization, UV emission lines

majority of this subsample does arise from AGN activity. Figure 5.4 shows two example ELG spectra. These objects typically exhibit narrow lines such as [OII]λ3727, Hβ, and [O III]λλ4959,5007, and often have narrow [Ne III] λ3869 emission, CaHK λλ3934, 3968 absorption, and the continuum break at 4000 ˚A (D4000). Narrow [NeV] λ3426 and other high ionization lines are not detected in our ELG spectra—sources with such lines are classified as NLAGN.

• Absorption-Line Galaxies (ALG):We distinguish between galaxies showing emission lines (ELG) and early-type galaxies (ALG), where the latter have continua marked only by absorption features, notably the D4000 continuum break and the CaHKλλ3934, 3968 absorption lines. Figure 5.5shows an example spectrum.

Figure 5.5 Example of one of the eight SEXSI ALG. The ALG are identified by CaHK λλ3934, 3968 absorption and the break at 4000 ˚A, typical of early-type galaxies. No emission features are detected

• Stars: SEXSI fields are selected to be at high Galactic latitude to avoid contami- nating our extragalactic sample with 2 – 10 keV emitting stars, but we do identify a small number of Galactic stars as optical counterparts (at z = 0). Seven of the optically bright SEXSI sources are identified in the literature as stars (Paper II); the other sources so identified are from our spectroscopy of fainter sources. Section5.7.6 discusses the bright stars in more detail and assesses the possibility that the optically fainter objects are chance coincidences.

As mentioned above, these classifications depend only on the optical spectroscopic ap- pearance, not on X-ray properties such as luminosity or intrinsic obscuring column density.

With the exception of only a few sources, the identified extragalactic SEXSI sources have X-ray luminosities which suggest the presence of an accreting supermassive black hole. The emission-line galaxies, which are prevalent in our sample, do not show any optical indication of emission lines from atoms ionized by an X-ray source with copious hard X-ray emission.

Instead, the ELG lines are typical of normal galaxies with lines from atoms excited by at best moderately energetic photons that can be produced thermally by the hottest stars.

This apparent discrepancy in the optical and X-ray source properties is discussed further in§ 5.10.

In Table 5.2 we present the catalog of 477 hard-band SEXSI sources with optical spectroscopic data; the catalog is also available in machine-readable format in the online version of the Astrophysical Journal. Complete X-ray data and optical photometry for these sources are presented in Papers I and II, respectively. The remaining∼550 unidentified sources from the complete sample of 1034 hard-band SEXSI sources do not have optical spectroscopic data and are omitted from this catalog. The first six columns present the X-ray source data, while the following columns present optical counterpart information – photometric data followed by spectroscopic data. The final columns describe the X-ray luminosity and the column density – quantities determined by combining the X-ray data with the redshift.

Column 1 presents source names, designated by “CXOSEXSI” followed by standard truncated source coordinates. X-ray source positions, α_x and δ_x, corrected for the mean X-ray-to-optical offsets to eliminate Chandra pointing errors, are shown in columns 2 – 3. Column 4 lists the off-axis angle (OAA, the angular distance in arcmin of the source position from the telescope aim point). The 2 – 10 keV flux (in units of 10⁻¹⁵erg cm⁻² s⁻¹), converted from counts assuming Γ = 1.5 and corrected for Galactic absorption, is presented in column 5, while column 6 gives the source hardness ratio,HR= (H−S)/(H+S), where H andSare photons cm⁻² s⁻¹ in the 2 – 10 keV and 0.5 – 2 keV bands, respectively. Here, as in Paper II, we quote hardness ratios derived from the net soft X-ray counts recorded at the hard-band source position when there was not a significant soft-band source detected (as distinct from Paper I, in which these cases were reported as HR = 1). In addition, for a subset of these cases, when the soft-band counts recorded at the hard-band position were less than twice the soft-band background counts, the HR is considered a lower limit, is flagged as such in the catalog, and is set to HR = (H −S_limit)/(H +S_limit), where Slimit= 2 × soft-band background counts corrected by the exposure map.

Table5.2Notes

a X-ray positions are corrected for average X-ray to optical offset (to correct Chandra pointing errors); see Paper II

b HR= (H−S)/(H+S) where H is the corrected counts in the 2.0 – 10 keV band and S is the corrected counts in the 0.5 – 2.0 keV band. See§5.5for details

c See Paper II, §4 for details of the flag code. Briefly: 0 = no optical coverage, 1 = solid optical ID, 2 = upper limit, 3 = saturated in SEXSI optical image; R-band magnitude taken from the Guide Star Catalog II (McLean et al. 2000), 4 = solid ID butR-band magnitude affected by nearby bright source, 5 = more than one optical source consistent with the X-ray source position, 6 = upper limit (no optical counterpart) but area contaminated by nearby bright source so limiting magnitude is unknown

d BLAGN = Broad-Lined AGN, NLAGN = Narrow-Lined AGN, ELG = Emission Line Galaxy, ALG = Absorption Line Galaxy. See§5.4for classification details

e Notes (Column 13):

• A:optical counterpart falls just outside the strict search area (see§5.5and Table5.3).

• B: identification from the Guide Star Catalog II (McLean et al. 2000) or VIZIER database.

• C: identification from the Einstein Observatory Extended Medium-Sensitivity Survey (Stocke et al. 1991), object MS1214.3+3811.

• D:cataclysmic variable, spectrum shows 274 km s⁻¹ blueshift.

• E: member of (non-target) nearby galaxy, NGC 5879. This galaxy happened to be in theChandrapointing of SEXSI field QSO 1508. The three 2 – 10 keV sources spectroscopically confirmed to be associated with NGC 5879 are flagged.

• F:this object was identified using its 2-D spectrum as it could not easily be extracted to form a 1-D spectrum; the observable wavelength range is thus omitted.

• G: in Paper II this source had optflag=5 (>1 optical source in the search area). Our spectrum shows a BLAGN, thus we have changed the source to optflag=1, a secure optical counterpart identification.

• H:confirmed target cluster member (spectroscopically confimred within 1 Mpc of target cluster center). In Papers I and II sources were flagged as being potentially within 1 Mpc of the target cluster center as determined by their position in the image. These sources were all ignored for the logN−logS calculation in Paper I. Now that redshift information is available, only sources at the target clusterzremain flagged. See§5.11for details on these sources.

• I:confirmed (non-target) cluster/group detected inHolden et al.(2002) — see§5.11.

• J:possible BALQSO.

• K:line identification or redshift tentative.

• L: this source spectrum shows two ELG, one at z=0.426, one at z=1.432. The nearer source matches the R=22.25 in our photometry (Paper II), but the fainter z=1.432 source, undetected in our photometry, also appears in the error circle. This source is thus eliminated from our analysis.

• M:J145215.6+430448: low-ionization, broad absorption line quasar.

• N:spectrum has gap of>100 ˚A between red and blue side.

f Optical spectroscopic wavelenth coverage in angstroms

g Columns 16-18 present the logarithm of the best-fit NH value, as well as 1σ low and 1σ high values from the fit. When aNH measurement is zero we report ’<’ in the table

h HRis lower limit

i ∆λis in the observed frame — no zwas measured, only continuum

j Source detected on an off-axis ACIS-S chip (2-3) and thusN_His calculated fromHR, not spectral fit. See§5.5

k N_H is lower limit

l Bad XSPEC fit. N_H is calculated fromHR, not spectral fit

The data describing the optical counterparts begin in column 7, with the photometric optical counterpart flag (optflag), a code essential for interpreting the optical photometric data (see Table5.2footnote). Note that in this spectroscopic catalog the majority of entries in this column are optflag = 1, indicating a solid optical identification, since a successful spectroscopic identification depends on having a counterpart bright enough that emission lines or absorption features are detectable. In a handful of cases the optical flag is a 2, indicating a limiting magnitude. These cases occur either when we placed a slitlet on an optical counterpart identified in a band other thanR, or when a slitlet was placed ‘blindly’

at the X-ray source position even though no optical counterpart was present to the depth of our imaging data.

Column 8 is the R-band magnitude of the optical counterpart; in the next column we show the limitingRmagnitude for the image from which the optical counterpart, or a limit thereto, was derived. Next we present the logarithmic X-ray-to-optical flux ratio (column 10), given by the relation

log (fx/fo) = logf2−10 keV+ (R/2.5) + 5.50, (5.1) derived using the Kron-CousinsR-band filter transmission function (see Paper II and refer- ences therein). Note that special attention must be paid to the optical flag when interpreting the data of columns 8 – 10. For example, if the code is a 2 (optical counterpart not detected), then columns 8 and 10 describe limits on each quantity.

The optical spectroscopic data begins with the redshift in column 11, followed by the classification in column 12 (see § 5.4 for details of the redshift and classification determi- nations). Column 13 provides notes on individual sources where necessary.

The rest-frame wavelength range in angstroms for each optical spectrum is recorded in column 14; when a source spectrum shows continuum only and no redshift has been

determined, we present the observed-frame wavelength range. This column is essential for determining which spectral features are accessible for a given source. It is important to know, for example, whether the absence of high-ionization lines (typical of AGN and necessary for an AGN classification) is a consequence of non-detection in the measured spectrum or as the result of inadequate spectral coverage. In most cases both the blue and red sides of the spectrographs were employed; if this is the case and there is a significant spectral coverage gap (>100 ˚A) between the red and blue sides, a note is added in column 13.

Column 15 presents the log of the absorbed rest-frame 2 – 10 keV X-ray luminosity in erg s⁻¹, calculated from the hard-band flux (column 5) and the redshift assuming an X-ray photon index of Γ = 1.5.

The final three columns (16–18) present the log of the neutral hydrogen column density (NH) in cm⁻² and the associated 1 σ lower- and upper-limit to the value. These values are determined by X-ray spectral fitting of each source using XSPEC,⁴ a spectral fitting program. Since many SEXSI sources have a low number of counts in the X-ray we did not allow a many-free-parameter fit; instead, we performed the fits assuming an intrinsic power-law spectrum with photon index Γ = 1.9 typical of AGN continua. We fixed Γ and the Galactic N_H at z = 0 and allowed only the intrinsic column density at the source redshift to vary. The Galactic NH value used for each field is given in Paper I, Table 2.

The photoelectric absorption was determined using Wisconsin cross sections (Morrison &

McCammon 1983). The fitting was performed using C-statistic minimization instead of chi-squared minimization since the observed data bins have few counts (Cash 1979, and the XSPEC Manual, Appendix B). The fits use data from 0.3 – 7.0 keV, to match the energy range we used to extract counts in Paper I. The X-ray spectral data analysis was aided greatly by acis extract⁵ Version 3.91 (Broos et al. 2002), software written in IDL that assists in performing the many CIAO and XSPEC tasks involved in analyzing the spectra of large numbers of sources observed with ACIS. For the spectral analysis presented here we use CIAO Version 3.2 and CALDB Version 3.1.

Spectra were extracted for each source with a spectroscopic redshift (excluding stellar sources at z = 0). We choose 1.4967 keV as the primary PSF energy at which the PSF
