New flavours in Galactic Surveys: HOPS and MALT - Andrew Walsh Colloquium

ATNF Marsfield Lecture Theatre

Abstract

HOPS is the H$_2$O southern Galactic Plane Survey. Over the past three
years, we have surveyed 100 square degrees of the Galactic plane with the Mopra radiotelescope in the 12mm band. The survey focuses on many
spectral lines that are most relevant to high mass star formation within
the Galaxy. I will report on early results from HOPS as well as how we
hope to use the full data set.

MALT is the Millimetre Astronomers Legacy Team - a collaboration of
national and international astronomers who intend to utilise the fast
mapping capabilities of Australian millimetre telescopes to study high
mass star formation across the southern Galaxy. I will focus on MALT-45,
which will use the ATCA to survey a large portion of the Galaxy in
multiple spectral lines around 45GHz. This survey will push the recently
upgraded ATCA to its limits with fast, wide-scale mapping in multiple
spectral lines and continuum, as well as using both auto-correlation and
cross-correlation for the first time.
