![]() Two teams of researchers are using ASKAP’s unique capabilities to investigate these enigmatic events and their host galaxies simultaneously. “We are keen to study fast radio bursts and their host galaxies in great detail, not just to solve an intergalactic mystery but because they can tell us more about the structure and evolution of galaxy systems,” she said. “Research like this is necessary for studying the environments around the mysterious radio bursts, as galaxies are made up of more than just stars. This suggests that either a massive star that caused the fast radio burst was born another way, or that this powerful burst was created by something else entirely," he said.Ĭo-author Dr Karen Lee-Waddell, Director of the Australian SKA Regional Centre and the Project Scientist of WALLABY, said astronomers can so far study the ‘host’ galaxy for only a few fast radio bursts and this new discovery highlights the importance of finding many more. “What we’ve seen in this new paper is that the host galaxy itself appears undisturbed, quiet even. ![]() In this research, we aren't seeing those same clear signals of a turbulent galaxy,” Dr Glowacki said. “Of the radio bursts where we’ve studied their host galaxies in detail, we’ve seen colliding and merging galaxies. Marcin Glowacki from the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) led the latest research using CSIRO’s ASKAP radio telescope on Wajarri Yamaji Country in Western Australia.ĭr Glowacki said while previous studies suggest colliding galaxies could create massive stars that may eventually cause fast radio bursts, this paper's findings challenge that idea. New results published today in The Astrophysical Journal indicate the source of the interstellar blast is in a much calmer galactic environment than other known events. Researchers using a telescope owned and operated by CSIRO, Australia’s national science agency, have detected a ‘fast radio burst’ in a nearby galaxy that questions what we know about how the phenomena form.
