COMP2CAT hunting double-compact radio sources in the local Universe. (2019)

Keywords : galaxies active - galaxies: jets

Abstract:We present a catalog of compact double radio galaxies (hereafter COMP2CAT) listing 43 edge-brightened radio sources whose projected linear size does not exceed 60 kpc, the typical size of their host galaxies. This is the fifth in a series of radio source catalogs recently created, namely: FRICAT, FRIICAT, FR0CAT, and WATCAT, each of which focuses on a different class of radio galaxies. The main aim of our analysis is to attain a better understanding of sources with intermediate morphologies between FR IIs and FR 0s. COMP2CAT sources were selected from an existing catalog of radio sources based on NVSS, FIRST and SDSS observations because they have i) edge-brightened morphologies typical of FR IIs, ii) redshifts z<0.15, and iii) ...(more)

Characteristics of the 43 radio galaxies in COMP2CAT. For each galaxy, we show equatorial coordinates, redshifts, fluxes and luminosities at 1.4GHz, flux densities at 0.15GHz, spectral indexes between 1.4GHz and 0.15GHz, [OIII] fluxes, luminosities and equivalent widths, r-band absolute magnitudes, u-r, w1-w2 and w2-w3 colors, concentration indexes, Dn(4000) indexes, stellar velocity dispersions and their errors, black hole masses, physical sizes and asymmetric indexes (as described in the text). Luminosities, distances and sizes have been computed adopting a flat cosmology with H0=69.6km/(s.Mpc), Omega_M_=0.286 and Omega_Lambda=0.714.
