Title: Ca ii and Na i absorption signatures from the circumgalactic gas of the Milky Way
Author(s): Bekhti, Nadya Ben; Murphy, M. T.; Richter, P.; Westmeier, T.
Abstract: Spiral galaxies are surrounded by large gaseous halos that represent the interface between the condensed galactic discs and the surrounding circumgalactic medium. A powerful method for studying the properties and nature of these circumgalactic gaseous structures is the analysis of absorption-line systems in the spectra of distant quasars (e.g., [3, 4]). Here we concentrate on the study of metal-line absorption systems in the halo of our own galaxy and link them with the distribution of neutral gaseous structures in the Milky Way as seen in Hi 21-cm emission. Our sample contains in total 106 sight lines towards quasars observed in the optical with VLT/UVES.
