Abstract
| The
circumgalactic medium of typical
galaxies represents a new frontier
in the pursuit of a complete
theory of galaxy formation.
Understanding the nature and
evolution of this material over
cosmic time is a crucial element
of galaxy formation theory, as it
is the main source of fuel for
star formation and is the material
that is most sensitive to the
ill-understood feedback processes
that regulate galaxy growth.
Circumgalactic baryons are only
now coming within observational
grasp thanks in particular to the
study of absorbers found in
background quasars. Astronomers
will therefore soon have the
opportunity to study the material
that is infalling onto, or
outflowing from typical galaxies.
We propose here to review the
technique, recent results and
future propects of the field. |
