The GMRT study of extremely faint dwarf irregular galaxies
Ayesha Begum, Jayaram N. Chengalur
We present results of deep, high velocity resolution (1.6 kms) Giant Meterwave Radio Telescope (GMRT) HI 21 cm-line observations of a sample of extremely faint (M$_B>-…
Kinematics of Extremely Faint Dwarf Galaxies
Ayesha Begum, Jayaram N. Chengalur
We present the results of deep, high velocity resolution (~1.6 km/s) Giant Meterwave Radio Telescope (GMRT) HI 21cm observations of extremely faint (M_B > -12.5) dwarf irregular ga…
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…
GMRT Observations of Low z Damped Lyman-alpha Absorbers
Jayaram N Chengalur, Nissim Kanekar
We present Giant Metrewave Radio Telescope (GMRT) observations of redshifted HI 21cm absorption in two low redshift (z=0.2212, z=0.0912) damped Lyman-alpha systems seen towards the…
