Abstract:
The extended environment of galaxies contains a wealth of information
about the formation and life cycle of galaxies which are regulated by
accretion and feedback processes. Observations of neutral hydrogen are
routinely used to image the high brightness disks of galaxies and to
study their kinematics. Deeper observations will give more insight
into the distribution of diffuse gas in the extended halo of the
galaxies and the inter-galactic medium, where numerical simulations
predict a cosmic web of extended structures and gaseous filaments.
To observe the extended environment of galaxies, column density
sensitivities have to be achieved that probe the regime of Lyman limit
systems. HI observations are typically limited to a brightness
sensitivity of NHI∼1019cm-2, but this must be improved upon by ∼2
orders of magnitude.
