Abstract:
We present the second part of an H-band (1.6um) "atlas" of z<0.3
3CR radio galaxies, using the Hubble Space Telescope Near Infrared
Camera and Multi-Object Spectrometer (HST NICMOS2). We present new
imaging for 21 recently acquired sources and host galaxy modeling for
the full sample of 101 (including 11 archival) - an 87% completion
rate. Two different modeling techniques are applied, following those
adopted by the galaxy morphology and the quasar host galaxy
communities. Results are compared and found to be in excellent
agreement, although the former breaks down in the case of sources with
strong active galactic nuclei (AGNs). Companion sources are tabulated,
and the presence of mergers, tidal features, dust disks, and jets are
cataloged. The tables form a catalog for those interested in the
structural and morphological dust-free host galaxy properties of the
3CR sample, and for comparison with morphological studies of quiescent
galaxies and quasar host galaxies.
Description:
In HST cycle 13 (2004-2005) we embarked on a Near-Infrared Camera and
Multi-Object Spectrometer (NICMOS) H-band snapshot imaging campaign of
z<0.3 3CR sources (Madrid et al., 2006, Cat. J/ApJS/164/307, Paper I).
The SNAP program is now complete, having continued through cycle 14
(2005-2006) at reduced priority. Since publication of Paper I (which
presented images for the first 69 targets, observed during cycle 13)
an additional 22 sources have been successfully observed, and images
for these new targets are presented here. Finally, archival data for
an additional 11 objects previously observed with NICMOS2 in F160W
were obtained from the Multimission Archive at Space Telescope (MAST).
