Abstract:
The head-tail (HT) morphology of radio galaxies is seen for a class of
radio sources where the primary lobes are being bent in the
intercluster weather due to strong interactions between the radio jets
and their respective intracluster medium. A systematic search has been
carried out for new HT radio galaxies from the Very Large Array Faint
Images of the Radio Sky at Twenty-Centimeters survey database at
1400MHz. Here, we present a catalog of 717 new HT sources, among which
287 are narrow-angle tail (NAT) sources whose opening angle between
the two lobes is less than 90°, and 430 are wide-angle tail (WAT)
whose the opening angle between the two lobes is greater than 90°.
NAT radio sources are characterized by tails bent in a narrow "V"-like
shape; the jet bending in the case of WAT radio galaxies are such that
the WATs exhibit wide "C"-like morphologies. Optical counterparts are
found for 359 HT sources. We report HT sources with luminosity ranges
1038≤L1.4GHz≤1045erg/s and redshifts up to 2.01. The various
physical properties of these HT sources are mentioned here. Some
statistical studies have been done for this large number of newly
discovered HT sources.
Description:
We visually examined each of the 95243 selected sources from the last
data release (2014 December 17) of the VLA FIRST survey at 1400MHz.
Based on the morphology, we found a total of 717 head-tail (HT)
sources from the sample. A few of them are single component and most
of them are multicomponent. Depending on the bending angle of the two
lobes, we classified them as narrow-angle tail (NAT) or wide-angle
tail (WAT). We visually cross-matched our HT sample with SDSS data for
the optical counterpart.
