Abstract:
We present near-IR spectroscopy in the J- and H-bands for a large
sample of 243 X-ray-selected, moderate-luminosity Type 1 active
galactic nuclei (AGNs) in the COSMOS, SXDS, and E-CDF-S survey fields
using the multi-object spectrograph Subaru/FMOS. Our sample covers the
redshift range 0.5≤z≤3.0 and X-ray luminosity range of
1043≤L[2-10keV]≤1045erg/s. We provide emission-line properties
and derived virial black hole mass estimates, bolometric luminosities,
and Eddington ratios, based on Hα (211), Hβ (63), and MgII
(4). We compare line widths, luminosities, and black hole mass
estimates from Hα and Hβ, and augment these with
commensurate measurements of MgII and CIV detected in optical spectra.
We demonstrate the robustness of using Hα, Hβ, and MgII as
reliable black hole mass estimators for high-z moderate-luminosity
AGNs, while the use of CIV is prone to large uncertainties (≥0.4dex).
We extend a recently proposed correction based on the CIV blueshift to
lower luminosities and black hole masses. While our sample shows an
improvement in their CIV black hole mass estimates, the deficit of
high blueshift sources reduces its overall importance for
moderate-luminosity AGNs compared to the most luminous quasars. In
addition, we revisit luminosity correlations between Lbol,
L[2-10keV], L[OIII], L5100, and LHα and find them to be
consistent with a simple empirical model, based on a small number of
well-established scaling relations. Finally, we highlight our highest
redshift AGN, CID 781, at z=4.6, which has the lowest black hole mass
(∼108M☉) among current near-IR samples at this redshift and is
in a state of fast growth.
Description:
Observations for the multi-object spectrograph Subaru/FMOS
low-resolution (LR; R∼600) survey (Matsuoka+ 2013ApJ...771...64M 2013ApJ...771...64M) and
Akiyama+ 2015PASJ...67...82A 2015PASJ...67...82A) over the full COSMOS field were obtained
between 2010 and 2012 (semesters S10B-S12A).
The FMOS high-resolution (HR; R∼2600) survey (Silverman+ 2015,
J/ApJS/220/12) in COSMOS was conducted between 2012 and 2016, with
observations of the central square degree carried out in 2012-2014 and
of the outer area in 2015-2016.
Observations in SXDS were carried out between 2009 and 2011 in
guaranteed, engineering, and open-use time over 22 pointings (in LR mode).
Initial results for a subset of 43 AGNs of our sample in COSMOS and
E-CDF-S have been presented in Matsuoka+ (2013ApJ...771...64M 2013ApJ...771...64M).
For the fields of COSMOS and E-CDF-S, almost all of the Type 1 AGNs
considered here had prior spectroscopic redshifts from optical
spectroscopy obtained from several observing programs in COSMOS
(Lilly+ 2007, J/ApJS/172/70 ; Trump+ 2007, J/ApJS/172/383 ; Coil+

and E-CDF-S (Szokoly+ 2004, J/ApJS/155/271 ; Popesso+ 2009A&A...494..443P 2009A&A...494..443P ;
Silverman+ 2010, J/ApJS/191/124), as listed in Marchesi+ (2016,
