Constraints on the gas masses of low-z damped Lyman-$\alpha$ systems

Parichay Mazumdar, Nissim Kanekar, J. Xavier Prochaska

We report a deep search for redshifted HI 21 cm emission from three damped and sub-damped Lyman-$\alpha$ absorbers (DLAs) at $z\approx 0.1$ with the Green Bank Telescope (GBT). No evid…
