HI deficiency in groups : what can we learn from Eridanus
A. Omar
The HI content of the Eridanus group of galaxies is studied using the GMRT observations and the HIPASS data. A significant HI deficiency up to a factor of 2-3 is observed in galaxi…

The electron temperatures of HII regions S 201, S 206, and S 209 : Multi-frequency GMRT observations
Amitesh Omar, J. N. Chengalur, D. A. Roshi
Three Galactic HII regions, viz., S 201, S 206, and S 209 have been imaged at three frequencies, viz., 232, 327, and 610 MHz using the GMRT. The resolutions of these images are typ…
