A Search for Extended Radio Sources in 1.3 sr of the VLA Sky Survey (VLASS)

Understand

We report preliminary results of a visual inspection of ~4300 deg$^2$ covered by 4414 images of the 3-GHz VLA Sky Survey (VLASS, epoch 1.1) in search of extended radio structures.

• Over 7600 positions were registered, and for a subset of 270 of the most promising candidates their host objects were searched in optical and infrared surveys, as well as in other public databases.
• Among these 270, we found 9 new giant radio galaxies with a projected radio extent exceeding 1 Mpc, of which two are likely quasars at a redshift of z$\sim$2, and another one had hitherto been misidentified with a low-redshift host.
• Apart from various sources with unusual radio morphologies, we found numerous remnant-type double radio sources with very diffuse lobes in VLASS, both with and without radio cores.
