Abstract:
We present a sample of 74 radio sources with recurrent jet activity.
The sample consists of 67 galaxies, 2 quasars and 5 unidentified
sources, selected from the published data or are newly recognized. The
sample's redshift range is 0.002<z<0.7 and the size of inner and
outer structures varies from 0.02 to 4248kpc. We analyse the optical
and radio properties of the sample and compare them with the
characteristics of ordinary one-off FRII radio sources. With the help
of stellar population modelling, we derive black hole masses and
stellar masses of host galaxies of 35 restarting radio sources,
finding that the black hole masses in restarting radio sources are
comparable to those of typical single-cycle FRII radio sources. The
obtained median values of log MBH are 8.58 and 8.62M☉.
Unlike the black hole masses, the stellar masses in restarting radio
sources tend to be smaller than in the FRII sources. Although the
stellar populations of the hosts of recurrent activity sources are
dominated by old stars, a significant fraction of young stars can be
observed as well. Based on the Sloan Digital Sky Survey photometric
observations, we also analyse the morphology of the host galaxies and
obtained significantly smaller concentration indices for the
restarting radio sources when compared to the classical FRII hosts.
This effect can be interpreted as a result of frequent merger events
in the history of host galaxies of restarting radio sources.
Description:
Our sample of restarting radio sources contains 74 objects, including
67 galaxies, 2 quasars and 5 unidentified sources. The selection was
based mostly on the published data, but we also included new sources,
recognized recently by the authors of this paper.

Note (1): Notes as follows:
T = For two objects, J1409-0302 and J1325-4301, we wrote two values of lout
and Sout, which correspond to the length and flux density of the middle
and outer lobes, respectively
+ = newly recognized restarting radio galaxies
* = restarting radio galaxies with inner lobes more luminous than the
outer ones.
a = A new DDRS
b = Flux density measured at 1.5GHz
c = This source is counted as radio relic associated with a giga-hertz peaked
source (GPS) by Stanghellini et al. (2005A&A...443..891S 2005A&A...443..891S) and by
Shulevski (2015, PhD thesis, Univ, Groningen). However, the optical DSS
map (see the attached figure in the appendix) reveals a weak extended
emission in the vicinity of the extended diffuse relic. Therefore, in our
opinion, the association is questionable. Deep optical observation are
necessary.
d = Triple-double radio galaxy
e = The structure should be confirmed the flux density of 1120mJy is for the
