325-MHz observations of the ELAIS-N1 field using the Giant Metrewave Radio Telescope
S. K. Sirothia, M . Dennefeld, D. J. Saikia +3
We present observations of the European Large-Area {\it ISO} Survey-North 1 (ELAIS-N1) at 325 MHz using the Giant Metrewave Radio Telescope (GMRT), with the ultimate objective of i…
Deep low-frequency observations with the Giant Metrewave Radio Telescope: a search for relic radio emission
S. K. Sirothia, D. J. Saikia, C. H. Ishwara-Chandra +1
We present deep multifrequency observations using the Giant Metrewave Radio Telescope at 153, 244, 610 and 1260 MHz of a field centered on J0916+6348, to search for evidence of fos…
Detection of the 2175Å~ extinction feature and 21-cm absorption in two MgII systems at z~1.3
R. Srianand, N. Gupta, P. Petitjean +2
We have discovered two dusty intervening MgII absorption systems at z~1.3 in the Sloan Digital Sky Survey (SDSS) database. The overall spectra of both QSOs are red (u-K>4.5 mag) an…
A multifrequency study of giant radio sources I. Low-frequency Giant Metrewave Radio Telescope observations of selected sources
C. Konar, M. Jamrozy, D. J. Saikia +1
We present low-frequency observations with the Giant Metrewave Radio Telescope (GMRT) of a sample of giant radio sources (GRSs), and high-frequency observations of three of these s…
Radio morphology and spectral analysis of cD galaxies in rich and poor galaxy clusters
S. Giacintucci, T. Venturi, M. Murgia +5
We present a radio morphological study and spectral analysis for a sample of 13 cD galaxies in rich and poor clusters of galaxies.} Our study is based on new high sensitivity Giant…
NGC4438 and its environment at radio wavelengths
Ananda Hota, D. J. Saikia, Judith A. Irwin
We present multi-frequency, radio-continuum and HI observations of NGC4438, the highly-disturbed, active galaxy in the Virgo cluster, with the VLA and the GMRT. High-resolution obs…
