Early science results from ASKAP

ASKAP has recently started its Early Science program with 12 MkII PAF-equipped antennas and 36 beams simultaneously covering a 30 square degree field of view. The first observations have focused on mapping extragalactic neutral hydrogen in galaxy groups and clusters selected by the `WALLABY' Survey Science Team. Significant efforts from engineers, software designers, and scientists are overcoming obstacles and paving the way to most effectively utilized the new hardware and software developed for ASKAP. Preliminary results are quite promising and indicate a very successful scientific future for ASKAP.
