A new catalogue of head-tail radio galaxies from LoTSS DR1
  The peculiar morphology of Head-Tail (HT) radio galaxies indicates strong
interactions between the radio jets and their intra-cluster medium. We
systematically search for HT radio galaxies from LOFAR Two-metre Sky Survey
first data release (LoTSS DR1) at 144 MHz frequency. We present here a
catalogue of fifty new HT radio sources, among them, five are Narrow-Angle
Tailed sources (NATs) and forty-five are Wide Angle Tailed sources (WATs). NATs
are characterized by tails bent in a narrow V like shape with less than a
ninety-degree opening angle. For WAT radio galaxies, the opening angle between
jets is more than ninety degrees which exhibit wide C like morphologies. We
found that thirty-one out of fifty HT sources are associated with known galaxy
clusters. The various physical properties and statistical studies of these HT
sources are also presented in this paper.
