An international scientific team, including the researchers from the Instituto de Astrofísica de Canarias (IAC) Cristina Ramos Almeida, Patricia Bessiere and Giovanna Speranza, has discovered that quasars, some of the brightest and most powerful objects in the Universe, are mainly ignited by mergers between galaxies. The finding sheds new light, after years of controversy, on what causes the emission of large amounts of energy in the most powerful active nuclei. The research has used observations from the Isaac Newton Telescope (INT) and the William Herschel Telescope (WHT) at the Roque de
An international team of researchers, with participation from the Instituto de Astrofísica de Canarias, has discovered an extremely dense Neptune-sized planet, which challenges the conventional theories about the formation and evolution of planets. It was first identified with NASA’s TESS satellite, and the present studies were made with the HARPS-N spectrograph on the Telescopio Nazionale Galileo (TNG), at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands). The results of the study have been published in the journal Nature. It is called TOI-1853b and is really
