| ASKAP zoom bands |

The Australian SKA Pathfinder Array (ASKAP) Early Science and
Commissioning (ACES) team has started reviewing the data from the newly
available "zoom" modes on ASKAP, which provide higher spectral resolution.
Observations were made of a test
field in the Galactic Plane with a frequency resolution of 1.1kHz
(about 0.2 km/s) at 1.6 GHz. The field contains at least 20 known 1665-MHz
OH masers, of which so far 19 have been confirmed within the new ASKAP
data. The above spectra of known 1665-MHz OH maser G335.789+0.174
were taken with ASKAP on 5 February 2019 (red) and the ATCA on 28 February 2019
(blue). As can be seen, the spectral structure matches well between
the ASKAP and ATCA observations.
As Friday 19th and Monday 22nd April are the Easter public holidays in Australia, the next ADAP will be Tuesday 23rd April. |
