Giant radio galaxies in the LOFAR deep fields

We present their host galaxies with either spectroscopic (when available) or else photometric redshift estimates culled from various different references, and use these to estimate their projected linear sizes.

We compare the radio, optical properties of GRGs with those of a control sample of smaller RGs, and explored their environment in terms of the surface number density of neighbouring galaxies within these surveys. Integrated flux densities and radio luminosities were determined for a subset of RGs through available survey images at 50, 150, 610, and 1400 MHz to compute integrated spectral indices. We find that GRGs preferentially reside in sparser environments compared to their smaller counterparts.
