Abstract:
We present the third catalog release of the wide-area (31.3deg2)
Stripe 82 X-ray survey. This catalog combines previously published
X-ray source properties with multiwavelength counterparts and
photometric redshifts, presents 343 new spectroscopic redshifts, and
provides black hole masses for 1297 Type 1 active galactic nuclei
(AGN). With spectroscopic redshifts for 3457 out of 6181 Stripe 82X
sources, the survey has a spectroscopic completeness of 56%. This
completeness rises to 90% when considering the contiguous portions of
the Stripe 82X survey with homogeneous X-ray coverage at an optical
magnitude limit of r<22. Within that portion of the survey, 23% of AGN
can be considered obscured by being either a Type 2 AGN, reddened
(R-K>4, Vega), or X-ray obscured with a column density of
NH>1022cm-2. Unlike other surveys, there is only an 18% overlap
between Type 2 and X-ray obscured AGN. We calculated black hole masses
for Type 1 AGN that have Sloan Digital Sky Survey spectra using virial
mass estimators calibrated on the Hβ, MgII, Hα, and CIV
emission lines. We find wide scatter in these black hole mass
estimates, indicating that statistical analyses should use black hole
masses calculated from the same formula to minimize bias. We find that
the AGN with the highest X-ray luminosities are accreting at the
highest Eddington ratios, consistent with the picture that most black
hole mass accretion happens in the phase when the AGN is luminous
(L2-10keV>1045erg/s).
Description:
The current release of the Stripe 82X catalog combines the X-ray
information in the LaMassa+ (2016, J/ApJ/817/172) catalog (DR1) with
the multiwavelength counterpart identification and photometric
redshifts released in the Ananna+ (2017, J/ApJ/850/66) catalog (DR2),
as well as preexisting spectroscopic redshifts from independent
surveys, spectroscopic redshifts obtained through the special SDSS-IV
eBOSS program (LaMassa+ 2019, J/ApJ/876/50), and spectroscopic
redshifts determined from dedicated ground-based observing campaigns
with Palomar and Keck. This catalog also contains black hole masses
calculated from fitting the SDSS spectra of Type 1 AGN in Stripe 82X.
We used DoubleSpec on the 5m Palomar telescope to target optical
counterparts brighter than r=22 (AB) and the Low Resolution Imaging
Spectrometer (LRIS) and DEep Imaging Multi-Object Spectrograph
(DEIMOS) on the 10m Keck telescopes to target optical sources fainter
than r=22. In the 2022 fall observing run, we reached the milestone
of observing every optical counterpart to an X-ray source from
XMM-Newton observing campaigns in AO10 (XMM-AO10) and AO13
(PI: C. M. Urry; LaMassa+ 2013, J/MNRAS/436/3581 and
2016, J/ApJ/817/172) brighter than r=22.
This catalog release includes 343 new spectroscopic redshifts and
classifications of Stripe 82X sources from both our optical and
near-infrared campaigns that have not been previously published.

Note (1): From Evans+ 2010ApJS..189...37E 2010ApJS..189...37E (see IX/57 ; see also the Chandra
table in LaMassa+ 2016, J/ApJ/817/172 ;
<[LUC2013] MSID NNNNN> in Simbad)
Set to 0 for XMM sources.
Note (2): For archival and AO10 [PI: Urry C.M., ObsIDs: 0673000101
("Stripe 82 XMM field 1"), 0673002301 ("Stripe 82 XMM field 2");
see LaMassa+ 2013, J/MNRAS/436/3581] and
AO13 (PI: Urry C.M.; Proposal ID 074283;
LaMassa+ 2016, J/ApJ/817/172 ; <[LUC2013] NNNNN> in Simbad)
XMM sources.
Set to 0 for Chandra sources.
Note (3): XMM or Chandra Observation ID number for observation in which source
is detected.
Note (4): Possible values are Chandra, XMM_archive,
XMM_AO10 (LaMassa+ 2013, J/MNRAS/436/3581), or
XMM_AO13 (LaMassa+ 2016, J/ApJ/817/172).
Note (5): A powerlaw model with Γ=2.0 is assumed to convert count rates
to flux.
Note (6): If corresponding flux measurements are 0, these values represent the
upper limit. Values are for Chandra sources only.
Note (7): Given by detml=-lnPrandom_. For all significant Chandra
detections, det_ml is set to a fiducial value of 11.0439,
representing a 4.5σ detection which we required to include a
source in the LogN-LogS analysis in LaMassa+ (2013, J/MNRAS/436/3581
and 2016, J/ApJ/817/172).
For the XMM sources, we required det_ml≥15 to include a source in
the LogN-LogS analysis of LaMassa+ (2013 and 2016).
Note (8): Calculated for sources with a spectroscopic redshift and where
det_ml>10.
Note (9): 2-10keV for XMM and 2-7keV for Chandra. A powerlaw model with
Γ=1.7 is assumed to convert count rates to flux.
Note (10): 0.5-10keV for XMM and 0.5-7keV for Chandra. A powerlaw model with
Γ=1.7 is assumed to convert count rates to flux.
Note (11): Multiwavelength counterpart to X-ray source. Coordinates may be from
SDSS, then VHS, then Spitzer. See Ananna+ 2017, J/ApJ/850/66
for details.
Note (12): See Ananna+ 2017, J/ApJ/850/66 for details. Code as follows:
0.0 = No association found, or counterpart is from the
LaMassa+ 2016ApJ...818...88L 2016ApJ...818...88L catalog;
1.0 = Unambiguous association;
1.5 = Conflicting associations, but a secure match in one band helps to
resolve ambiguity;
2.0 = Counterparts disagree among multiwavelength bands matched to X-ray
source, but the counterpart in one band exceeds the LR threshold to
accept the association as the true counterpart, while the LR value
was below the threshold in the other band;
3.0 = Counterparts disagree among multiwavelength bands and the LR values
are comparable. The association with the greater reliability value
is chosen as the counterpart;
4.0 = A counterpart is found only in one multiwavelength band.
Note (13): See Morrissey+ (2007ApJS..173..682M 2007ApJS..173..682M). Extinction-corrected.
Note (14): From the coadded catalogs of
Fliri & Trujillo (2016, J/MNRAS/456/1359), if available,
otherwise from Jiang+ (2014ApJS..213...12J 2014ApJS..213...12J). Extinction-corrected
when extinction information is available.
Note (15): From the VISTA VHS survey using a 2.8 or 5.6" radius aperture
for point or extended sources, respectively
(McMahon+ 2013Msngr.154...35M 2013Msngr.154...35M, see II/367).
Extinction-corrected.
Note (16): From the UKIDSS Large Area Survey using a 2.8 or 5.6 radius
aperture for point or extended sources, respectively
(Lawrence+ 2007MNRAS.379.1599L 2007MNRAS.379.1599L, see II/319). Extinction-corrected.
Note (17): See Timlin+ 2016, J/ApJS/225/1 ; Not extinction-corrected.
Note (18): See Papovich+ 2016ApJS..224...28P 2016ApJS..224...28P ; Not extinction-corrected.
Note (19): AllWISE (Cutri+ 2014, II/328) instrumental profile-fit photometry
(wnmpro, where n refers to band number) and error for point sources
or elliptical aperture magnitude and error (wngmag) for extended
sources (where WISE-Ext is set to YES). Not extinction-corrected.
Note (20): WISE magnitudes with S/N<2 should be considered an upper limit.
Note (21): Reported magnitudes refer to elliptical magnitudes if set to YES.
Note (22): See White+ 1997ApJ...475..479W 1997ApJ...475..479W ; Cat. VIII/92.
Note (23): Due to the low space density of these sources, counterparts were
found using nearest neighbor matching in LaMassa+ 2016, J/ApJ/817/172
Note (24): See Viero+ 2014, J/ApJS/210/22
Note (25): Class as follows:
QSO = 2568 occurrences
QSO(BA = 1 occurrence
QSO_BAL = 1 occurrence
GALAXY = 722 occurrences
STAR = 142 occurrences
AGN = 5 occurrences
NELG = Narrow emission-line galaxy (2 occurrences)
Note (26): See Table 8 for spectroscopic information from surveys and archival
catalogs and Tables 9-10 for spectroscopic information from our
ground-based follow-up campaign.
Note (27): Fit quality is close to that of photoz.
Note (28): Morphology of source according to SED template fitting for
calculating photoz with LEPHARE
(Arnouts & Ilbert 2011ascl.soft08009A). Code as follows:
1 = Star;
2 = Elliptical galaxy;
3 = Spiral galaxy;
4 = Type 2 AGN;
5 = Starburst galaxy;
6 = Type 1 AGN;
7 = QSO.
Note (29): Source morphology according to optical or NIR photometry:
point-like, extended, or uncertain (see Ananna+ 2017, J/ApJ/850/66).
Note (30): We used the following ranked ordering as described in the main text:
Hb = The Hβ emission line formula from Shen+ 2024ApJS..272...26S 2024ApJS..272...26S
MgII = The MgII emission line formula from Shen+ 2024ApJS..272...26S 2024ApJS..272...26S
Ha = The Hα emission line formula from Greene+ 2010ApJ...709..937G 2010ApJ...709..937G
CIV = The CIV emission line formula from Shen+ 2024ApJS..272...26S 2024ApJS..272...26S
Note (31): Due to the widespread dispersion when comparing black hole masses
from the same AGN using different formulas, we recommend that
statistical analyses use black hole masses calculated using the
same formula.
Note (32): Estimate of the k-corrected, non absorption corrected hard X-ray
band (2-10keV) luminosity from the X-ray count rate. This value
represents the hard X-ray band luminosity if there is a significant
detection in the hard X-ray band. Otherwise, the X-ray luminosity
in the full or soft X-ray band is scaled to derive Lx, as
described in the main text. This value is only calculated for
sources with spectroscopic redshifts that are extragalactic.
