The data fills in the “comparative lack of detailed radio observations” of Abell 3266—revealing several radio structures for the first time and providing an “unprecedented” look at several others—according to a study published in the Monthly Notices of the Royal Astronomical Society on Monday. The discoveries also fulfill Riseley’s nearly decade-long quest to spot a radio halo, a type of huge diffuse structure seen at the center of some galaxy clusters, among other exotic radio sources.“Out of thousands of known clusters, only around 100 are known to host some combination of relics and/or haloes, so these are fairly rare and enigmatic objects,” Riseley said in an email. “We need to find more of them to really be confident that we understand the details of how they’re generated.”
