Abstract:
We present a catalog of 349 giant radio sources (GRSs including both
galaxies and quasars). The database contains all giants known to date
from the literature. These GRSs cover the redshift range of
0.016<z<3.22 and include radio sources of projected linear sizes
larger than 0.7Mpc, which extend up to 4.7Mpc. We provide the
principal parameters (i.e., exact position of the host in the sky,
redshift, angular and projected linear size, red optical magnitude,
radio morphology type, total radio flux density, and luminosity) for
all the sources, as well as characteristics of the sample. Based on
the distribution of GRSs in the sky, we identify regions where there
is a paucity of giants, so that future surveys for this type of
objects could concentrate primarily in these fields. From the analysis
presented here, we estimate a lower limit for the expected number of
GRSs as about 2000, for the resolution and sensitivity limits of
FIRST, NRAO VLA Sky Survey and Sloan Digital Sky Survey surveys.
Compared with earlier compilations, there is a significant increase in
the number of large giants with sizes >2Mpc, as well as those at high
redshifts with z>1. We discuss aspects of their evolution and suggest
that these are consistent with evolutionary models.
Description:
In this paper, we present a catalog of giant radio sources (GRSs)
known to date. We provide their principal parameters as well as
characteristics of the sample. In this compilation of GRSs we do not
consider objects such as cluster radio relics and/or radio halos that
can also exceed our defining size of 700kpc.
For several years we have been browsing the literature, including
survey results, and analyzing data to search for radio galaxies of
large linear sizes. We focused mostly on the existing compilations of
giants, as well as published studies of individual sources of such
types, but also examined well-studied samples such as 3CRR (Laing+,
1983, J/MNRAS/204/151) and compilations of structures of radio sources
such as, for example, that by Nilsson (1998, J/A+AS/132/31). In effect
we have compiled a list of all GRSs known to the end of 2017.
