HI Galaxy Science

This working group is focused on the history of gas in our universe through the study of atomic HI line emission and absorption, mainly at redshifts from ~0 to ~1.5.

HI Galaxy Science Working Group Introduction

The HI Galaxy Science Working Group is focused on studying the formation and evolution of galaxies by mapping the 21-cm spectral line of neutral atomic hydrogen (HI) in absorption and emission, over cosmic time.

Using SKA we will conduct deep HI observations of millions of galaxies out to redshift z>1. Our primary goals are to investigate the structure and dynamics of cold gas in and around galaxies, explore the gas-halo interface, discover plumes and streams of intergalactic gas, as well as map large-scale galaxy structures and their peculiar motions.
