A Bursting Radio Transient in the Direction of the Galactic Center (2008)
Ray, Paul S., Hyman, Scott D., Lazio, T. Joseph, Kassim, Namir E., Roy, Subhashis, Kaplan, David L., ...
The radio sky is poorly sampled for rapidly varying transients because of the narrow field-of-view of most imaging radio telescopes at cm and shorter wavelengths. The emergence of sensitive long...
Extragalactic sources towards the central region of the Galaxy (2007)
Roy, Subhashis, Rao, A. Pramesh, Subrahmanyan, Ravi
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 rotation measure near...
Roy, Subhashis, Rao, A. Pramesh, Subrahmanyan, Ravi
To determine the properties of the Faraday screen and the magnetic field near the central region of the Galaxy, we measured the Faraday rotation measure (RM) towards 60 background extragalactic...
A Faint, Steep Spectum Burst from the Radio Transient GCRT J1745-3009 (2007)
Hyman, Scott D., Roy, Subhashis, Pal, Sabyasachi, Lazio, T. Joseph W., Ray, Paul S., Kassim, Namir E., ...
GCRT J1745-3009 is a transient bursting radio source located in the direction of the Galactic center. It was discovered in a 330 MHz VLA observation from 2002 September 30--October 1 and subsequently...
A New Radio Detection of the Bursting Source GCRT J1745-3009 (2005)
Hyman, Scott D., Lazio, T. Joseph W., Roy, Subhashis, Ray, Paul S., Kassim, Namir E.
GCRT J1745-3009 is a transient bursting radio source located in the direction of the Galactic center, discovered in 330 MHz VLA observations from 2002 September 30--October 1 by Hyman et al. We have...
The Galactic Centre region (2004)
We have observed the central 45' region of the Galaxy at 620 MHz band of the Giant Metrewave Radio Telescope (GMRT) in radio continuum, and measured the polarisation properties of 64 small diameter...
The Galactic centre region (2004)
We have observed the central 450 region of the Galaxy at 620 MHz band of the Giant Metrewave Radio Telescope (GMRT) in radio continuum, and measured the polarisation properties of 64 small diameter...
Sgr A* at low radio frequencies: GMRT observations (2004)
Roy, Subhashis, Rao, A. Pramesh
The central region of the Galaxy has been observed at 580, 620 and 1010 MHz with the Giant Metrewave Radio Telescope (GMRT). We detect emission from Sgr-A*, the compact object at the dynamical centre...
Constraints on distances to Galactic Centre non-thermal filaments from HI absorption (2003)
We have studied HI absorption towards three non-thermal filaments (NTFs) Sgr-C, G359.54+0.18 and G359.79+0.17 using the Giant Metrewave Radio Telescope (GMRT). Our study, for the first time,...
GMRT observations of four suspected supernova remnants near the Galactic Centre (2001)
Roy, Subhashis, Rao, A. Pramesh
We have observed two fields - Field-I (l=3.2 degrees, b=-1.0 degree) and Field-II (l=356.8 degrees, b=-0.1 degree) with the Giant Metrewave Radio Telescope (GMRT) at 330 MHz. In the first field, we...
