MRC B0319-454: Probing the large-scale structure with a giant radio galaxy
V. Safouris, R. Subrahmanyan, G. V. Bicknell +1
We present an investigation of the relationships between the radio properties of a giant radio galaxy MRC B0319-454 and the surrounding galaxy distribution with the aim of examinin…
The genesis of morphologies in extended radio sources: X-shapes, off-axis distortions and giant radio sources
Lakshmi Saripalli, Ravi Subrahmanyan
We examine relationships between the morphology in double radio sources and the radio-optical position angle offset--the relative orientation of the radio axis with respect to the…
Multiwavelength study of the bright X-ray source population in the interacting galaxies NGC5774/NGC5775
Kajal K. Ghosh, Douglas A. Swartz, Allyn F. Tennant +5
A few nearby interacting galaxies are known that host elevated number of ultraluminous X-ray sources. Here we report the results of a multiwavelength study of the X-ray source popu…
Restarting engine in an X-shaped radio galaxy
Lakshmi Saripalli, Ravi Subrahmanyan, Tanmoy Laskar +1
J2018-556, an X-shaped FR-I radio galaxy provides a unique opportunity to discuss the formation scenarios for the extended structures seen in this class of radio sources. An unders…
A circumnuclear disk of atomic hydrogen in Centaurus A
R. Morganti, T. Oosterloo, C. Struve +1
We present new observations, performed with the Australia Telescope Compact Array, of the HI absorption in the central regions of Centaurus A. For the first time, absorption is det…
PKS B1545-321: Bow shocks of a relativistic jet?
V. Safouris, R. Subrahmanyan, G. Bicknell +1
Sensitive, high resolution images of the double-double radio galaxy PKS B1545-321 reveal detailed structure, which we interpret in the light of previous work on the interaction of…
