Abstract:
We have conducted a new Arecibo survey for HI emission for 113
galaxies with broad-line (type 1) active galactic nuclei (AGNs) out
to recession velocities as high as ∼35000km/s. The primary aim of the
study is to obtain sensitive HI spectra for a well-defined, uniformly
selected sample of active galaxies that have estimates of their black
hole masses in order to investigate correlations between HI properties
and the characteristics of the AGNs. HI emission was detected in 66
out of the 101 (65%) objects with spectra uncorrupted by radio
frequency interference, among which 45 (68%) have line profiles with
adequate signal-to-noise ratio and sufficiently reliable inclination
corrections to yield robust deprojected rotational velocities. This
paper presents the basic survey products, including an atlas of HI
spectra, measurements of HI flux, line width, profile asymmetry,
optical images, optical spectroscopic parameters, as well as a summary
of a number of derived properties pertaining to the host galaxies. To
enlarge our primary sample, we also assemble all previously published
HI measurements of type 1 AGNs for which we can estimate black hole
masses, which total an additional 53 objects. The final comprehensive
compilation of 154 broad-line active galaxies, by far the largest
sample ever studied, forms the basis of our companion paper, which
uses the HI database to explore a number of properties of the AGN host
galaxies.
Description:
The sample of 113 newly observed Arecibo objects, contains two
subsamples. The first comprises 98 type 1 AGNs from the Fourth Data
Release of the Sloan Digital Sky Survey (SDSS; Adelman-McCarthy et al.
2006, Cat. II/267); the 15 objects of the second subsample were
primarily chosen because they have been studied with reverberation
mapping (Kaspi et al., 2000ApJ...533..631K 2000ApJ...533..631K; Peterson et al.,
2004ApJ...613..682P 2004ApJ...613..682P).

Note (1): Format SDSS JHHMMSS.ss+DDMMSS.s except for the last fifteen
objects named with a NGC, PG, RX, MCG, Akn or 3C designation.
Note (2): Defined as the ratio of Petrosian radii enclosing 50%-90% of the light
Note (3): For SDSS objects, morphological type was estimated either from C,
following Shimasaku et al. (2001AJ....122.1238S 2001AJ....122.1238S), or from visual
inspection of the images presented in Fig. 1; for non-SDSS objects,
this was either taken from the RC3 or estimated from visual inspection
of HST images, where available. See text. We use conventional notation
for most objects, except in cases where we cannot distinguish a true
elliptical vs. an S0 (E/S0) or between a true S0 vs. a spiral (S0/Sp).
"Sp(d)" denotes a tidally disturbed spiral.
Note (4): Measured at a surface brightness level of µ=25mag/arcsec2
in the g and B band for SDSS and non-SDSS (from Hyperleda) objects,
respectively.
Note (5): Calculated from q using Hubble's (1926ApJ....64..321H 1926ApJ....64..321H) formula
assuming q0=0.3 (Fouque et al., 1990ApJ...349....1F 1990ApJ...349....1F). The values
for SDSS J080538.66+261005.4 and SDSS J080546.97+260532.9 were
estimated visually.
Note (6): Calculated assuming H0=70km/s/Mpc, Ωm=0.27, and
ΩΛ=0.73
Note (7): Corrected for Galactic extinction; SDSS objects are given in the
g band and non-SDSS objects in the B band.
Note (8): Derived from stars (Barth et al., 2005ApJ...619L.151B 2005ApJ...619L.151B; Greene &
Ho, 2006ApJ...641L..21G 2006ApJ...641L..21G ; this work). Additional data come from Onken
et al. (2004ApJ...615..645O 2004ApJ...615..645O) (3C 120), Nelson et al.
(2004ApJ...615..652N 2004ApJ...615..652N) (Akn 120, NGC 3227, NGC 5548, NGC 7469), and
Nelson & Whittle (1995ApJS...99...67N 1995ApJS...99...67N) (MCG +01-13-012).
Note (9): Flag as follows:
a = Taken from Greene & Ho (2006ApJ...641..117G 2006ApJ...641..117G)
b = Possibly unreliable.
w = Not derived from stars but from the width of the [OII]λ3727 line,
as described in Greene & Ho (2005ApJ...627..721G 2005ApJ...627..721G).
Note (10): Data for the non-SDSS objects come from Peterson et al.
(2004ApJ...613..682P 2004ApJ...613..682P), except for MCG +01-13-012 (Stirpe,
1990A&AS...85.1049S 1990A&AS...85.1049S) and RX J0602.1+2828 and RX J0608.0+3058 (Motch
et al., 1998A&AS..132..341M 1998A&AS..132..341M, measured from the published spectra,
which were kindly sent to us by C. Motch).
Note (11): the printed paper indicates a luminosity expressed in
solar luminosities, but the actual unit is erg/s (10-7W).
For the non-SDSS objects, the Hα luminosity was estimated
from the 5100Å continuum luminosity of Peterson et al.
(2004ApJ...613..682P 2004ApJ...613..682P), using the L(Hα)-L(5100Å) correlation
(eq. [1]) of Greene & Ho (2005ApJ...630..122G 2005ApJ...630..122G), with the exception of
MCG +01-13-012 (Stirpe, 1990A&AS...85.1049S 1990A&AS...85.1049S) and RX J0602.1+2828 and
RX J0608.0+3058 (Motch et al., 1998A&AS..132..341M 1998A&AS..132..341M), whose published
Hβ luminosities were converted to Hα assuming
Hα/Hβ=3.5 (see Greene & Ho, 2005ApJ...630..122G 2005ApJ...630..122G).
Note (12): Derived from the Hα method (eq. [6]) of Greene & Ho
(2005ApJ...630..122G 2005ApJ...630..122G), except for the reverberation-mapped objects,
whose masses were taken directly from Peterson et al.
(2004ApJ...613..682P 2004ApJ...613..682P), and MCG +01-13-012, RX J0602.1+2828, RX
J0608.0+3058, whose masses are based on the Hβ method (eq. [7])
of Greene & Ho (2005ApJ...630..122G 2005ApJ...630..122G). For consistency with the virial
mass zero point adopted by Greene & Ho (2005ApJ...630..122G 2005ApJ...630..122G), all the
reverberation-mapped masses were reduced by a factor of 1.8 (see
footnote 4 in Greene & Ho, 2005ApJ...630..122G 2005ApJ...630..122G).
Note (13): Assuming Lbol=9.8L(5100Å) (McLure & Dunlop,
2004MNRAS.352.1390M 2004MNRAS.352.1390M), with L(5100Å) estimated from the
L(Hα)-L(5100Å) correlation of Greene & Ho
(2005ApJ...630..122G 2005ApJ...630..122G).

Note (1): In the case of the reverberation-mapped objects, the Hβ

luminosity, using the L(Hβ)-L(5100Å) correlation (eq. [2]) of
Greene & Ho (2005ApJ...630..122G 2005ApJ...630..122G).
Note (2): Derived either from the Hβ method of Greene & Ho

given to the latter if available. Masses from the latter method come
