Abstract:
We present newly acquired images of the near-infrared counterpart of
3CR radio sources. All the sources were selected to have a redshift of
less than 0.3 to allow us to obtain the highest spatial resolution.
The observations were carried out as a snapshot program using the
Near-Infrared Camera and Multiobject Spectrograph (NICMOS) on-board
the Hubble Space Telescope (HST). In this paper we describe 69 radio
galaxies observed for the first time with NICMOS during HST cycle 13.
All the objects presented here are elliptical galaxies. However, each
of them has unique characteristics such as close companions, dust
lanes, unresolved nuclei, arclike features, globular clusters, and
jets clearly visible from the images or with basic galaxy subtraction.
Description:
All the observations presented here were carried out with NICMOS
Camera 2 (NIC2) on MULTIACCUM observing mode.
