A new 21-cm absorber identified with an galaxy
Nissim Kanekar, Ramana M. Athreya, Jayaram N. Chengalur
We present Giant Metrewave Radio Telescope (GMRT) observations of redshifted 21-cm absorption from the metal line absorption system towards PKS 1243-072. HI absorption is…
Molecular gas at intermediate redshifts
Nissim Kanekar, Jayaram N Chengalur
We present Giant Metrewave Radio Telescope (GMRT) observations of OH absorption in B3~1504+377 () and PKS 1413+135 (). OH has now been detected in absor…
HI in Abell 3128
Jayaram N. Chengalur, R. Braun, M. Wieringa
We discuss Australia Telescope Compact Array (ATCA) HI 21cm data for the galaxy cluster A3128. Our observations are intentionally relatively shallow, and a blind search through our…
GMRT Observations of Interstellar Clouds in the 21cm line of Atomic Hydrogen
Rekhesh Mohan, K. S. Dwarakanath, G. Srinivasan +1
Nearby interstellar clouds with high (|v| >/= 10 km/s) random velocities although easily detected in NaI and CaII lines have hitherto not been detected (in emission or absorption)…
Variable 21cm absorption at z=0.3127
Nissim Kanekar, Jayaram N Chengalur
We report multi-epoch GMRT HI observations of the z = 0.3127 damped absorber towards the quasar PKS 1127-145, which reveal variability in both the absorption profile and the flux o…
Arecibo imaging of compact high-velocity clouds
W. B. Burton, R. Braun, J. N. Chengalur
Ten isolated compact high-velocity clouds (CHVCs) of the type cataloged by Braun & Burton (1999) have been imaged with the Arecibo telescope and were found to have a nested core/ha…
