HI Absorption in a Gravitational Lens at z ~ 0.7645

Kanekar, N; Briggs, Franklin

Description

We have used the Westerbork Synthesis Radio Telescope to detect HI 21 cm absorption at z ∼ 0.7645 in the gravitational lens system towards PMN J0134-0931. The 21 cm profile has two broad components, with peak optical depths of 0.047 ± 0.007 and 0.039 �
