Astronomy AO helps detect Magnetar in the Cow

The Arecibo Observatory was one of 21 telescopes involved in the large-scale European Very Large Baseline Interferometry (VLBI) Network (EVN) radio observations of the astronomical explosion AT2018cow ('the Cow'). AO, which has the largest collecting area of all of the participating telescopes, helped boost the sensitivity of the extended VLBI baselines to detect the radio signals, producing high-resolution images that enabled scientists to determine that the highly unique supernova resulted in the creation of a magnetar – a neutron star with a very strong magnetic field.
