Ordinary Meeting [Hybrid Meeting] with Kovi Rose, University of Sydney and CSIRO/ATNF

Guest Speaker: Kovi Rose, University of Sydney and CSIRO/ATNF

Title: Building huge radio telescopes (and finding tiny stars)

Abstract: We have entered the age of big data in astrophysics and radio astronomy is no exception. The Australian SKA Pathfinder (ASKAP) conducts wide-field radio surveys of the southern skies. With millions of radio-bright sources in the survey regions we are using new polarisation filtering and positional cross-matching, as well as more traditional variability metrics, to identify interesting astronomical transients. From stellar radio emission to late-time supernova re-brightening, I will speak about some of the different objects we are finding with ASKAP, including the detection of periodic bursts from an ultracool brown dwarf star.

Biography: Kovi is an astrophysics PhD candidate and LSST Data Science Fellow at the University of Sydney who uses radio telescopes to study distant stars that go snap, crackle, and pop. Outside of research, he spends most of his time communicating science through his writing, podcasting, and memes.
