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 using the MeerKAT radio telescope have discovered a new giant radio galaxy, MGTC J100022.85+031520.4, in the COSMOS field. This galaxy, hosted by an elliptical galaxy with a redshift of 0.1034, spans about 4.2 million light years and is one of the few GRGs located in a galaxy cluster. The discovery, part of the MIGHTEE survey, provides insights into the formation and evolution of radio sources.
Astronomers from the University of Wisconsin-Madison have discovered 63 new giant radio galaxies (GRGs) using the Faint Images of the Radio Sky at Twenty cm survey (FIRST). GRGs are rare objects with a projected linear length exceeding 2.3 million light years and are important for studying the formation and evolution of radio sources. The researchers utilized the DRAGNhunter algorithm to identify double-lobed radio galaxies in the FIRST data and found the newfound GRGs at redshifts between 0.51 and 1.32. Further studies are needed to understand the properties of these GRGs.
