Astronomers traced a long-period radio transient to ASKAP J1745-5051, a magnetic white dwarf in a tight binary where accretion drives both radio and X-ray bursts every 81 minutes, uniting many previously puzzling LPT traits and offering a new framework for these cosmic signals (Nature Astronomy).
Astronomers using the ASKAP telescope discovered 15 new Giant Radio Galaxies, some over 12 million light-years wide, which are the largest single objects in the universe. These galaxies feature supermassive black holes that emit powerful jets, creating vast radio lobes, and their study helps understand galaxy growth and black hole activity cycles.
Astronomers have discovered a unique radio transient, ASKAP J1935+2148, with an unprecedented cycle of nearly an hour, exhibiting varying pulse patterns. Detected by the ASKAP radio telescope, this signal challenges current understanding of neutron stars and white dwarfs, suggesting the need for further research into these cosmic phenomena.
Astronomers at the University of California San Diego have discovered that odd radio circles (ORCs) in space are formed by outflowing winds from explosive events like supernovae, creating massive radio wave circles more than 50,000 times the diameter of the Milky Way. Using the ASKAP telescope, they observed that these ORCs are created by intense bursts of star formation and outflowing galactic winds, shedding light on the evolution of galaxies and the life cycle of these winds.
