Multi-frequency GMRT Observations of the HII regions S 201, S 206, and S 209 : Galactic Temperature Gradient
A. Omar, J. N. Chengalur, D. Anish Roshi
We present radio continuum images of three Galactic HII regions, S 201, S 206, and S 209 near 232, 327, and 610 MHz using the Giant Meterwave Radio Telescope (GMRT). The GMRT has a…

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…

HI 21cm imaging of a nearby Damped Lyman-alpha system
Jayaram N. Chengalur, Nissim Kanekar
We present Giant Metrewave Radio Telescope (GMRT) HI 21cm emission images of the z=0.009 damped Lyman-alpha (DLA) absorber towards the QSO HS 1543+5921. The DLA has been earlier id…
