| ASKAP Update for April |
|
The
ASKAP
Update for March includes reports on the status of survey operations, a new round
of Guest Science Projects, the first RACS-high data release,
GASKAP-HI parameter space exploration, and the recent ATUC open session.
The first set of Rapid ASKAP Continuum Survey high-frequency (RACS-high) observations
have been released on
CASDA
for general-purpose use. Roughly one-third of RACS-high has been processed
so far and further deposits will be made as the processing
progresses. It is planned to have all three RACS frequency bands available
in full within a few months. As an Observatory Project, RACS is
available to everyone and is currently the best wide-area survey at
radio frequencies between 700--1800 MHz.
The image above is from the standard pipeline processing of an EMU field containing the radio galaxy Hydra A. As is apparent, the presence of a very bright radio source in the field results in significant imaging artefacts around it. Efforts are continuing to determine the best way of improving the dynamic range and minimising artefacts in such fields. (Image credit: Emil Lenc) |
