Kinematics of Diffuse Interstellar Clouds :Recent GMRT Results
K. S. Dwarakanath
A high latitude HI 21 cm-line absorption survey toward extragalactic sources was recently completed using the Giant Meterwave Radio Telescope (GMRT). A total of 104 sources with mo…
GMRT HI imaging survey of ERIDANUS group of galaxies
Amitesh Omar, K. S. Dwarakanath, K. R. Anantharamaiah
This project aims to image a subset of galaxies in the nearby group Eridanus in HI emission and in radio continuum using the GMRT. The typical resolution of HI images will be $\sim…
Extended Extragalactic Radio Emission
F. N. Owen, M. J. Ledlow, J. A. Eilek +4
Extended radio emission and its relation to parent galaxy properties is briefly reviewed. Our current understanding of the relation between absolute radio and optical luminosity, r…
HI 21cm-line observations with the GMRT towards interstellar clouds previously seen in optical absorption
Rekhesh Mohan, K. S. Dwarakanath, G. Srinivasan +1
We have made HI 21cm-line absorption measurements using the GMRT towards 15 directions in the Galaxy which are known to have high random velocity clouds as seen in the optical abso…
The interstellar clouds of Adams and Blaauw revisited: an HI absorption study - II
Jayadev Rajagopal, G. Srinivasan, K. S. Dwarakanath
In the preceding paper (paper I), we presented HI absorption spectra towards radio sources very close to the lines of sight towards 25 bright stars against which optical absorption…
The interstellar clouds of Adams and Blaauw revisited: an HI absorption study - I
Jayadev Rajagopal, G. Srinivasan, K. S. Dwarakanath
This investigation is aimed at clarifying the nature of the interstellar gas seen in absorption against bright O and B stars. Towards this end we have obtained for the first time H…
