VizieR Online Data Catalog: LoTSS giant radio galaxies. I. (Dabhade+, 2020)
Abstract
The VAC of 318520 radio sources was at first refined based on the point source completeness, which is 90% at an integrated flux density of 0.5mJy for LoTSS DR1 (Shimwell et al., 2019, Cat. J/A+A/622/A1). The final sample size of GRGs from the VAC is 186 GRGs.
An independent manual visual search (MVS) was also carried out to search for GRGs in LoTSS DR1 to look for additional GRGs that were missed in the semi-automated method employed on the VAC. We combined both GRG samples (VAC and MVS) to form the final GRG catalogue of 239 GRGs (Table. A1). We find a total of 20 GRGs (Table A2) from our sample of 239 to be BCGs residing in dense cluster environments and hosted by BCGs of the clusters. (2 data files).- Publication:
