A team of scientists led by the Observatory of Munich University and the Instituto de Astrofísica de Canarias have obtained direct visualization of the process of feeding the supermassive black hole at the centre of the Andromeda galaxy. The study reveals the existence of long filamentary structures of gas and dust which move in a spiral starting at a distance from the black hole and ending up at the black hole itself. The results, which have been published in the Astrophysical Journal, were obtained using images from the Hubble and Spitzer space telescopes. The Andromeda Galaxy, which is

The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to mine. Taken during the experiment’s “survey validation” phase, the data include distant galaxies and quasars as well as Milky Way stars. The universe is big, and it’s getting bigger. To study dark energy, the mysterious force behind the accelerating expansion of our universe, scientists are using the Dark Energy Spectroscopic Instrument (DESI) to map more than 40 million galaxies, quasars, and stars. Today, the collaboration, which includes the Instituto de Astrofísica de Canarias (IAC)

International research led by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology. The study is published in the specialized journal Astronomy and Astrophysics. A team of scientists, led by the researcher at the IAC and the University of La Laguna (ULL) Sebastién Comerón, has found that the galaxy NGC 1277 does not contain dark matter.This is the first time that a massive galaxy (it has a mass several times that of the
