A new international study, using observations from the Gran Telescopio Canarias at the Roque de los Muchachos Observatory on La Palma, has identified a plasma bubble as the source of the persistent emission observed in some of the so-called fast radio bursts (FRBs), one of the most powerful and unknown cosmic events in the Universe. The data also allow researchers to constrain the nature of the “engine” powering these mysterious sources. The results are published today in Nature. Discovered just over a decade ago, fast radio bursts (FRBs) emit millisecond-long pulses that release an immense

A group of astrophysicists led by Mireia Montes, a researcher at the Instituto de Astrofísica de Canarias (IAC), has discovered the largest and most diffuse galaxy recorded until now. The study has been published in the journal Astronomy & Astrophysics, and has used data taken with the Gran Telescopio Canarias (GTC) and the Green Bank Radiotelescope (GBT). Nube is an almost invisible dwarf galaxy discovered by an international research team led by the Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of La Laguna (ULL) and other institutions. The name was

An international team of scientists, with participation by researchers at the Instituto de Astrofísica de Canarias (IAC), has discovered a very large, but thin, stream of stars in the Coma cluster of galaxies. This is the largest stream of stars detected until now, and the first to be found in a cluster of galaxies. This finding, which is published in the journal Astronomy and Astrophysics, was made using observations taken with the William Herschel Telescope (WHT) at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands). The Coma Cluster is a large cluster of galaxies
