Particle acceleration and dynamics of double-double radio galaxies: theory vs. observations
C. Konar, M. J. Hardcastle
In this paper we show that a small sample of radio galaxies with evidence for multiple epochs of jet activity (so-called `double-double' radio galaxies) have the same electron inje…
Episodic radio galaxies J01164722 and J1158+2621: can we constrain the quiescent phase of nuclear activity?
C. Konar, M. J. Hardcastle, M. Jamrozy +1
We present multifrequency radio observations of two well known episodic FR\,II radio galaxies (J01164722 and J1158+2621) and a detailed investigation of the life-cycle of episod…
Rejuvenated radio galaxies J0041+3224 and J1835+6204: how long can the quiescent phase of nuclear activity last?
C. Konar, M. J. Hardcastle, M. Jamrozy +2
We present radio observations of two well-known double-double radio galaxies, J0041+3224 and J1835+6204, at frequencies ranging from 150 to 8460 MHz, using both the Giant Metrewave…
The Dynamics of Radio Galaxies and Double-Double Radio Galaxies
C. Konar, M. Jamrozy, M. J. Hardcastle +4
Relativistic and magnetised plasma ejected by radio loud AGNs through jets form the diffuse lobes of radio galaxies. The radiating particles (electron/electron-positron) in lobes e…
Discovery of a spiral-host episodic radio-galaxy
Ananda Hota, S. K. Sirothia, Youichi Ohyama +6
We report the discovery of a unique radio galaxy at z=0.137, which could possibly be the second spiral-host large radio galaxy and also the second triple-double episodic radio gala…
A radio study of the double-double radio galaxy 3C293
S. A. Joshi, S. Nandi, D. J. Saikia +2
We present radio continuum observations at frequencies ranging from 150 to 5000 MHz of the misaligned double-double radio galaxy, DDRG, 3C293 (J1352+3126) using the Giant Met…
