On 9 and 10 April, the Canary Islands Institute of Astrophysics (IAC) will welcome two distinguished physicists: Serge Haroche, winner of the 2012 Nobel Prize in Physics, and F. Duncan Haldane, winner of the 2016 Nobel Prize in Physics. Both scientists have been invited by the IAC to take part in the 18th Congress of Physics Students (COEFIS), organised by students from the University of La Laguna, and will each give a lecture in the IAC Lecture Hall from 10.30 am. On Thursday 9 April, the IAC will welcome Professor Haroche, and on Friday 10 April it will be Professor Haldane’s turn. In both

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC) and the Gran Telescopio Canarias (GTC), has observed a dramatic change in a supermassive black hole. Located about 10 billion light-years away, the object dimmed to roughly one-twentieth of its former brightness in just two decades — an extraordinarily short interval on cosmic timescales. The discovery was made within a collaborative observing framework linking Japan’s Subaru Telescope with the GTC in Spain’s Canary Islands at the Roque de los Muchachos Observatory, in La Palma
