A High Galactic Latitude HI 21cm-line Absorption Survey using the GMRT：II. Results and Interpretation
clouds kinematics and dynamics radio lines
2009/5/14
We have carried out a sensitive high-latitude (|b| > 15◦)
HI 21 cm-line absorption survey towards 102 sources using the GMRT.
With a 3σ detection limit in optical depth of ∼0.01, this is...

We have used the Giant Meterwave Radio Telescope (GMRT)
to measure the Galactic HI 21-cm line absorption towards 102 extragalactic
radio continuum sources, located at high (|b| > 15◦) Galactic...
