Abstract:
Quasars behind the Galactic plane (GPQs) are important astrometric
references and valuable probes of Galactic gas, yet the search for
GPQs is difficult due to severe extinction and source crowding in the
Galactic plane. In this paper, we present a sample of
204 spectroscopically confirmed GPQs at |b|<20°, 191 of which are
new discoveries. This GPQ sample covers a wide redshift range from
0.069 to 4.487. For the subset of 230 observed GPQ candidates, the
lower limit of the purity of quasars is 85.2%, and the lower limit of
the fraction of stellar contaminants is 6.1%. Using a multicomponent
spectral fitting, we measure the emission line and continuum flux of
the GPQs, and estimate their single-epoch virial black hole masses.
Due to selection effects raised from Galactic extinction and target
magnitude, these GPQs have higher black hole masses and continuum
luminosities in comparison to the SDSS DR7 quasar sample. The
spectral-fitting results and black hole mass estimates are compiled
into a main spectral catalog, and an extended spectral catalog of
GPQs. The successful identifications prove the reliability of both our
GPQ selection methods and the GPQ candidate catalog, shedding light on
the astrometric and astrophysical programs that make use of a large
sample of GPQs in the future.
Description:
Spectroscopic observations for quasar behind the Galactic plane (GPQ)
candidates have been carried out with five telescopes in China, USA,
and Australia since 2018. A total of 243 GPQ candidates have been
observed until 2021 May, 230 of which are selected from the GPQ
candidate catalog in Paper I (Fu+ 2021, J/ApJS/254/6).
The Xinglong 2.16m Telescope (XLT) is an equatorial mount reflector at
Xinglong Observatory, National Astronomical Observatories, Chinese
Academy of Sciences. Since 2018, we have been using the Beijing Faint
Object Spectrograph and Camera on XLT to identify GPQ candidates with
low-resolution spectroscopy (R=265 at 5007Å).
The Lijiang 2.4m Telescope (LJT) is an altitude-azimuth mount
reflector operated by Lijiang Observatory, Yunnan Observatories,
Chinese Academy of Sciences. The instrument we use is the Yunnan Faint
Object Spectrograph and Camera on LJT (R∼250 at 6030Å).
The 200 inch (5.3m) Hale Telescope (P200) is operated by Palomar
Observatory. The Double Spectrograph (DBSP) has been used for the
observations (R∼900 at central wavelengths of blue (2500-5700Å) and
red (4800-10700Å) channels).
The 2.3m telescope (ANU23) at Siding Spring Observatory is operated by
the Australian National University. For all observations, we use the
Wide-Field Spectrograph (R∼3000, ∼3300-9000Å).
The McGraw-Hill 1.3m Telescope (MDM13) is operated by the MDM
Observatory, which is located adjacent to the Kitt Peak National
Observatory. We use the Boller and Chivens CCD Spectrograph
(resolution of ∼4.4Å/pixel).
Throughout this paper we adopt a flat ΛCDM cosmology with
ΩΛ=0.7 and h=0.7.

Global notes:
Note (G1): Pan-STARRS sources are named in Simbad.
Note (G2): Pan-STARRS coordinates from single epoch detections (weighted mean)
in equinox J2000 at the mean epoch given by epochMean
("Epoch" column, in Cat. II/349).
Note (G3): When a value is provided for logL1350 but the measurement error is
set to a null value, it is because the rest-frame 1350Å is close to the
edge of the spectrum. In such cases, black hole masses based on CIV
are not reported.
Note (G4): Telescope as follows:
LJT = The Lijiang 2.4m Telescope with the Yunnan Faint Object Spectrograph
and Camera (YFOSC; 76 occurrences)
XLT = The Xinglong 2.16m Telescope with the Beijing Faint Object
Spectrograph and Camera (BFOSC; 61 occurrences)
MDM13 = The McGraw-Hill 1.3m Telescope with the Boller and Chivens CCD
Spectrograph (28 occurrences)
P200 = The 200 inch (5.3m) Hale Telescope with the Double Spectrograph
(DBSP; 26 occurrences)
ANU23 = The 2.3m telescope at Siding Spring Observatory (operated by
the Australian National University) with the Wide-Field Spectrograph
(13 occurrences)
