ATCA search for 21 cm emission from a candidate damped Ly- absorber at z = 0.101
Nissim Kanekar, Jayaram N Chengalur, Ravi Subrahmanyan +1
We report a deep search for 21 cm emission/absorption from the candidate damped Lyman- system towards PKS 0439-433, using the Australia Telescope Compact Array (A…

Implications of 21cm observations for damped Ly- systems
Jayaram N Chengalur, Nissim Kanekar
We present Giant Metrewave Radio Telescope HI 21cm absorption observations, of candidate and confirmed damped Lyman- systems (DLAS). The derived spin temperatures (T_s) are in a…
