Abstract:
The goal of this work is to determine the nature of the relation
between morphology and accretion mode in radio galaxies, including
environmental parameters. The CoNFIG extended catalogue (improved by
new KS-band identifications and estimated redshifts from UKIRT
Infrared Deep Sky Survey (UKIDSS), and spectral index measurements
from new GMRT observations) is used to select a sub-sample of 206
radio galaxies with z≤0.3 over a wide range of radio luminosity,
which are morphology-classified using the Fanaroff-Riley (FR)
classification of extended radio sources. For each galaxy,
spectroscopic data are retrieved to determine the high/low excitation
status of the source, related to its accretion mode. Environmental
factors, such as the host galaxy luminosity and a richness factor, are
also computed, generally using the Sloan Digital Sky Survey data.
Description:
In order to complete the spectral index coverage of the CoNFIG1-4
samples, GMRT data were obtained on 2011 July 4 for 48 sources
(tablea1.dat).
Additional host-galaxy cross-identifications were performed using the
UKIRT Infrared Deep Sky Survey DR9 (UKIDSS; Lawrence et al. 2007, Cat.
II/314) (tablea3.dat and tablea4.dat).
