Abstract:
We use the spectroscopic data collected by the Magellanic Quasars
Survey (MQS) and the photometric V- and I-band data from the Optical
Gravitational Lensing Experiment (OGLE) to measure the physical
parameters for active galactic nuclei (AGNs) located behind the
Magellanic Clouds. The flux-uncalibrated MQS spectra were obtained
with the 4m Anglo-Australian Telescope and the AAOmega spectroscope
(R=1300) in a typical ∼1.5hr visit. They span a spectral range of
3700-8500Å and have signal-to-noise ratios in a range of 3-300. We
report the discovery and observational properties of 161 AGNs in this
footprint, which expands the total number of spectroscopically
confirmed AGNs by MQS to 919. After the conversion of the OGLE mean
magnitudes to the monochromatic luminosities at 5100, 3000, and
1350Å, we were able to reliably measure the black hole masses for
165 out of 919 AGNs. The remaining physical parameters we provide are
the bolometric luminosities and the Eddington ratios. A fraction of
these AGNs have been observed by the OGLE survey since 1997 (all of
them since 2001), enabling studies of correlations between the
variability and physical parameters of these AGNs.
Description:
In this paper, we analyze spectra for AGNs discovered behind the
Magellanic Clouds and obtained by the Magellanic Quasars Survey (MQS;
Kozlowski+ 2011, J/ApJS/194/22 and 2012, J/ApJ/746/27 and
2013, J/ApJ/775/92). The ∼4000 spectroscopically observed AGN
candidates were selected based on their mid-IR and optical colors,
optical variability in the OGLE-III survey, and the X-ray flux. They
were observed with the 4m Anglo-Australian Telescope (AAT) equipped
with the AAOmega spectroscope, producing a resolution of R∼1300 inside
a spectral range of 3700-8800Å in the 580V (blue channel) and 385R
(red channel) gratings.
We have reinspected all the MQS spectra in this analysis and
identified 161 additional AGNs, albeit faint (Table A1).
We also use the V- and I-band light curves from the Optical
Gravitational Lensing Experiment (OGLE; Udalski+ 1997AcA....47..319U 1997AcA....47..319U
2008AcA....58...69U 2008AcA....58...69U and 2015AcA....65....1U 2015AcA....65....1U) to calculate both the
monochromatic and bolometric AGN luminosities. The data have been
collected since 1997 with the 1.3m Warsaw Telescope located in Las
Campanas Observatory, Chile.
