Hydrogen Accretion in Local Galaxies (HALOGAS) Survey is a deep
survey of 24 local galaxies in the 21cm emission line of neutral
hydrogen. The aims of the survey are to understand the nature and
impact of thick HI disks in star-forming galaxies, and to quantify the
importance of cold gas accretion in maintaining the observed star
formation rate in the local Universe. HALOGAS is a forerunner to the
IMAGINE ATCA Legacy Survey.
Last week, the first data
release from the HALOGAS Survey (HALOGAS-DR1) was announced at the
PHISCC workshop in Perth. The data can be downloaded
from the survey webpage.
A second data release
will take place at the end of May 2019, coinciding with the completion
of the main survey outcome publications, and will include ancillary
optical, radio continuum, and single dish HI data.
The HALOGAS survey is led by George Heald, who joined CASS from ASTRON
several years ago.
