FAST survey of H I and OH absorption towards extragalactic radio sources
Yogesh Chandola, D. J. Saikia, Yin-Zhe Ma +5
Neutral atomic hydrogen and molecular gas in the host galaxies of radio active galactic nuclei (AGN) can be traced using H I 21-cm and OH-1667 MHz absorption lines to understand th…
An updated catalogue of giant radio sources
A. Kuźmicz, M. Jamrozy, K. Bronarska +2
We present a catalogue of 349 giant radio sources (GRSs including both galaxies and quasars). The database contains all giants known to date from the literature. These GRSs cover t…
Discovery of a red quasar with recurrent activity
S. Nandi, R. Roy, D. J. Saikia +6
We report a new double-double radio quasar, DDRQ, J07464526 which exhibits two cycles of episodic activity. From radio continuum observations at 607 MHz using the GMRT and 1400…
A study of the environments of large radio galaxies using SDSS
A. Pirya, D. J. Saikia, M. Singh +1
The distributions of galaxies in the environments of 16 large radio sources have been examined using the Sloan Digital Sky Survey. In the giant radio galaxy J1552+2005 (3C326) whic…
4C02.27: a quasar with episodic activity?
M. Jamrozy, D. J. Saikia, C. Konar
Striking examples of episodic activity in active galactic nuclei are the double-double radio galaxies (DDRGs) with two pairs of oppositely-directed radio lobes from two different c…
The dynamics of the giant radio galaxy 3C 457
C. Konar, M. J. Hardcastle, J. H. Croston +1
We present multi-frequency radio observations with the Giant Metrewave Radio Telescope and Very Large Array, and X-ray observations with the X-ray Multi-Mirror Mission ({\it XMM-Ne…
