The ASKAP
Update for January describes plans for the ASKAP Science Forum in
2022, the status of Pilot Surveys Phase II, commencement of RACS
(Rapid ASKAP Continuum Survey) high-band observations and plans for
the Review of ASKAP Survey Science Projects.
RACS-high, following low-band and mid-band all-sky surveys, consists
of 1493 fields, which are the same footprint and positions observed in
the mid-band survey. This is roughly 50% more than the number of
fields observed in RACS-low. Using the same integration time as both
other bands (15 minutes per field), observations need about three
weeks of continuous observing. Processing of RACS-mid is still
underway, but a few select fields from RACS-high have also been imaged
to check data quality. The results are very encouraging and
demonstrate the improved resolution available in ASKAP’s highest
frequency band. The image above is a comparison of a small region
observed in two RACS bands and NVSS, showing the improvement in
resolution with RACS. (Image credit: Emil Lenc)
