Description

The LIGO/Virgo O3 observing run (2019 Feb ­- 2020 Feb) presents a strategic opportunity to exploit ASKAP’s high survey speed in the radio follow­up of gravitational wave events. LIGO/Virgo is expected to identify ~1 binary neutron star merger/month with a median error region of 120­-150 square degrees. For events without a confirmed optical counterpart ASKAP is an ideal instrument to conduct blind searches for radio afterglows that will then be followed­-up at all wavelengths. In 2019 ASKAP will be able to detect events similar to GW170817, regardless of whether there is a counterpart at other wavelengths.

Current assumptions

Typically we can be relatively flexible about specific configurations etc. and can mostly work with what is available at the time.

Scheduling constraints

The observing requests will be in response to LIGO/Virgo triggers. If the source satisfies our constraints, we will typically want to observe within a couple of days after then event, and then potentially a week and month later. 

Processing considerations

Given the time-critical nature of some of the observations, it would be good if the data can be processed as soon as possible after the observing run. If we detect a counterpart it is important to release the results to the rest of the community quickly so that further observations (e.g. with the ATCA or VLA) can be conducted.
