An international research team led by researchers at the Instituto de Astrofísica de Canarias (IAC) has found a new method for measuring the masses of black holes based on the temperature of the gas which surrounds them when they are active. The results of the work have recently been published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS). The confirmation of the existence of black holes is one of the most basic results in astrophysics. There is a wide range of masses of black holes, from stellar-mass black holes, which are the result of the catastrophic final

An international research, in which a team from the Instituto de Astrofísica de Canarias (IAC) has participated, has provided new evidence for an enigmatic outburst from a galaxy 216 million light-years away, proposing a new interpretation based on a spontaneous flip of the magnetic field surrounding its central black hole. The study has used joint data from different satellites and telescopes, including the Telescopio Nazionale Galileo (TNG) and the Gran Telescopio Canarias (GTC), both located at the Roque de los Muchachos Observatory (Garafía, La Palma). The results will be published in

Through collaboration between the Instituto de Astrofísica de Canarias (IAC) and the Sociedade Portuguesa para o Estudo das Aves (SPEA) within the framework of the projects Interreg EELabs and LIFE Natura@night, on the night of the 12t to 13th of August, the sky-live.tv channel will broadcast the maximum activity of the Perseid meteor shower from Madeira and from the Roque de los Muchachos Observatory (Garafía, La Palma). Some 10% of the continental surface of the Earth is affected by light pollution, but if we take into account the SkyGlow produced by the effect of artificial lighting on
