Radio sources below the detection threshold and classified active galactic nuclei in the COSMOS field

dataset
posted on 2022-12-19, 09:12 authored by Jacques SmuldersJacques Smulders

The dataset used to select active galactic nucleus (AGN) candidates is labelled as  G_all.csv.  The two datasets selected by the two ensembles of neural controllers are labelled as  G_0_ensemble.csv and G_all_ensemble.csv respectively. The dataset of detected AGN is labelled as  agn.csv.  In these four datasets, each source is described by the following columns:

  • ra (right ascension)
  • dec (declination)
  • z (photmetric redshift)
  • sfr (star-formation rate [log solar mass per year])
  • mass (stellar mass [log solar mass])
  • ks (Ks aperture magnitude)

The final four columns are the IRAC filters, with the values following the underscore indicating the band (in units of micrometer):

  • S_3.6
  • S_4.5
  • S_5.8
  • S_8.0

The values for these fields are extracted from the COSMOS2015 multiwavelength catalogue. A non-detection in any of the fields is indicated by the 'NA' keyword. 

The .fits files for the four radiomaps are also attached:

  • VLA 3GHz
  • VLA 3GHz smoothed
  • VLA 1.4 GHz
  • MeerKAT
