The Roque de los Muchachos Observatory (ORM) of the Instituto de Astrofísica de Canarias (IAC), located on La Palma, has reached another important milestone with the installation of the camera of the LST-4, one of the four Large-Sized Telescopes (LST), which will be part of the Cherenkov Telescope Array Observatory (CTAO), currently under construction. The installation of the camera represents the completion of the telescope assembly and marks its transition to the commissioning phase. After a thorough performance evaluation at the IACTEC building, the IAC's technological and business

Researchers from the Instituto de Astrofísica de Canarias (IAC), in collaboration with the Instituto de Ciencias del Cosmos de la Universidad de Barcelona (ICCUB) and the Instituto de Estudios Espaciales de Cataluña (IEEC), have carried out the largest observational study to date on massive runaway stars including rotation and binarity in the Milky Way. This work, recently published in Astronomy & Astrophysics , sheds light on how these stellar “fugitives” are launched into space and what their properties reveal about their intriguing origins. Runaway stars are stars that travel through

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
