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…
J1420--0545: The radio galaxy larger than 3C236
J. Machalski, D. Kozieł-Wierzbowska, M. Jamrozy +1
We report the discovery of the largest giant radio galaxy, J1420-0545: a FR type II radio source with an angular size of 17.4' identified with an optical galaxy at z=0.3067. Thus,…
