The ASKAP
WALLABY survey
will observe the sky in the 21-cm line of neutral hydrogen (or HI)
at 30-arcsec resolution, detecting and imaging the gas distribution
in hundreds of thousands of external galaxies in the local Universe.
This will allow astronomers to gain a much improved understanding of
the processes involved in galaxy formation and evolution, and the
role of stellar and black hole feedback, gas accretion and galaxy
interactions in these processes.
Members of the WALLABY team held a busy week in Perth last week,
to discuss Early Science and Pilot Survey data
and address the relevant technical aspects of the project in
preparation for the full survey.
