Dane Kleiner colloquium: WALLABY early science - Results and brick walls
|The Australia Telescope National Facility Colloquium|
|15:00-16:00 Wed 25 Oct 2017|
WALLABY is the main extragalactic, wide-field HI survey that will be observed with ASKAP. Its primary aim is to examine the HI properties and large-scale distribution of up to 500'000 galaxies out to a redshift of z=0.26. I will present the progress of WALLABY early science including: preliminary results and obstacles we have encountered. My focus has been on processing observations of the NGC 7232 and M83 early science fields as well as improving the ASKAPsoft pipeline. I will present the HI images of the nearby spiral galaxy IC 5201, where combining multi-epoch observations have revealed detections of two dwarf satellite galaxies. Finally, I will give an overview of the ASKAPsoft pipeline, highlighting the improvements needed for WALLABY science.
