Radio continuum observations of new radio halos and relics from the NVSS and WENSS surveys
Radio Continuum: galaxies – Galaxies: Clusters: general, intracluster medium – Cosmology: large-scale structure of Universe
2011/10/20
Radio halos and relics are diffuse radio sources found in galaxy clusters showing significant substructure at X-ray wavelengths. These sources provide important information about non-thermal processes...

Variability of Extragalactic Objects in Relation to Redshift, Color, Radio Spectral Index and Absorption Lines
Galaxies active galaxies quasars
2009/5/20
Optical variability of extragalactic objects, viz., QSOs, BL Lacs and Seyfert galaxies has been monitored systematically over an appreciable period of time and a large amount of data have accumulated....

We have made observations of the associated HI absorption of a
high redshift radio galaxy 0902C34 at z D 3:395 with the Giant Meterwave
Radio Telescope in the 3231MHz band.We find a narrowabsorptio...
A SEARCH FOR CANDIDATE RADIO SUPERNOVA REMNANTS IN THE NEARBY IRREGULAR STARBURST

2009/3/3
We present the results of a search for new candidate radio su-
pernova remnants (SNRs) in the nearby starburst irregular galaxies NGC 4214
and NGC 4395 using archived radio observations made with th...
RADIO CONTINUUM STUDY OF THE LARGE MAGELLANIC CLOUD - SNR J0519-6926

2009/2/9
We present the results of new high resolution ATCA observations
of SNR J0519{6926. We found that this SNR exhibits a typical "horseshoe" ap-
pearance with ®={0.55§0.08 and D=28§1 pc. No polariza...
