A Multiwavelength Study of a Young, Z-shaped, FR I Radio Galaxy NGC 3801
Ananda Hota, Jeremy Lim, Youichi Ohyama +3
We present preliminary results from a multi-wavelength study of a merger candidate, NGC3801, hosting a young FR I radio galaxy, with a Z-shaped structure. Analysing archival data f…
HI gas in the rejuvenated radio galaxy 4C29.30
Yogesh Chandola, D. J. Saikia, Neeraj Gupta
We report the results of our observations of HI absorption towards the central region of the rejuvenated radio galaxy 4C29.30 (J0840+2949) with the Giant Metrewave Radio Telescope…
VLBA polarimetric observations of the CSS quasar 3C147
A. Rossetti, F. Mantovani, D. Dallacasa +3
Aims. We report new VLBA polarimetric observations of the compact steep-spectrum (CSS) quasar 3C147 (B0538+498) at 5 and 8.4GHz. Methods. By using multifrequency VLBA observations,…
A Multifrequency Study of Double-Double Radio Galaxies
M. Jamrozy, C. Konar, D. J. Saikia +1
One of the 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…
Spectral Ages of Giant Radio Sources
C. Konar, D. J. Saikia, M. Jamrozy +1
Multifrequency observations with the GMRT and the VLA are used to determine the spectral breaks in consecutive strips along the lobes of a sample of selected giant radio sources (G…
Possible Relic Lobes in Giant Radio Sources
S. Godambe, C. Konar, D. J. Saikia +1
We present low-frequency observations with the GMRT of three giant radio sources (J0139+3957, J0200+4049 and J0807+7400) with relaxed diffuse lobes which show no hotspots and no ev…
