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…
Extragalactic sources towards the central region of the Galaxy
Subhashis Roy, A. Pramesh Rao, Ravi Subrahmanyan
We have observed a sample of 64 small diameter sources towards the central -6 degree < l< 6 degree, -2 degree < b < 2 degree of the Galaxy with the aim of studying the Faraday rota…
First results from the ATCA 18 GHz pilot survey
R. Ricci, E. M. Sadler, R. D. Ekers +7
As a pilot study for the first all-sky radio survey at short wavelengths, we have observed 1216 sq. deg. of the southern sky at 18GHz (16mm) using a novel wide-band (3.4GHz bandwid…
Radio Monitoring of Supernova 2001ig: The First Year
S. D. Ryder, E. Sadler, R. Subrahmanyan +3
Supernova 2001ig in NGC 7424 has been observed with the Australia Telescope Compact Array at ~2 week intervals since its discovery, making this the best-studied Type IIb radio supe…
CMB observations using the SKA
Ravi Subrahmanyan, R. D. Ekers
We examine the prospects for observations of CMB anisotropy with the SKA; we discuss the advantages of interferometric SKA imaging, observing strategies, calibration issues and the…
ATCA and CMB anisotropies
Ravi Subrahmanyan
Australia Telescope Compact Array (ATCA) observations in sky regions selected to be low in foreground confusion have been used to infer limits on arcmin-scale CMB anisotropy in tot…
