Abstract:
We built a catalog of 219 FR I radio galaxies (FR Is), called FRICAT,
selected from a published sample and obtained by combining
observations from the NVSS, FIRST, and SDSS surveys. We included in
the catalog the sources with an edge-darkened radio morphology,
redshift ≥0.15, and extending (at the sensitivity of the FIRST
images) to a radius r larger than 30kpc from the center of the host.
We also selected an additional sample (sFRICAT) of 14 smaller
(10<r<30kpc) FR Is, limiting to z<0.05. The hosts of the FRICAT
sources are all luminous (-21≥Mr≥-24), red early-type galaxies
with black hole masses in the range 108≤MBH≤3x109M☉; the
spectroscopic classification based on the optical emission line ratios
indicates that they are all low excitation galaxies. Sources in the
FRICAT are then indistinguishable from the FR Is belonging to the
Third Cambridge Catalogue of Radio Sources (3C) on the basis of their
optical properties. Conversely, while the 3C-FR Is show a strong
positive trend between radio and [O III] emission line luminosity,
these two quantities are unrelated in the FRICAT sources; at a given
line luminosity, they show radio luminosities spanning about two
orders of magnitude and extending to much lower ratios between radio
and line power than 3C-FR Is. Our main conclusion is that the 3C-FR Is
just represent the tip of the iceberg of a much larger and diverse
population of FR Is.
Description:
We built a catalog of 219 FR I radio galaxies, called FRICAT, selected
from the Best & Heckman (2012, Cat. J/MNRAS/421/1569) sample, and
obtained by combining the SDSS, NVSS, and FIRST surveys.
