In the standard cosmological model (𝜦CDM), galaxies are merely the visible "tips of the icebergs," residing within massive, invisible cocoons of dark matter known as haloes. While these haloes dictate the evolution and motion of galaxies, measuring their true size and mass has long been one of the most challenging tasks in astrophysics. A new study published in Astronomy & Astrophysics by Claudio Dalla Vecchia and Ignacio Trujillo from the Instituto de Astrofísica de Canarias (IAC) proposes a breakthrough: a physically motivated definition of a galaxy’s edge that acts as a precision "ruler"Advertised on -
The ONCE is dedicating its lottery ticket for Sunday, June 29, to the 40th anniversary of the Instituto de Astrofísica de Canarias (IAC). Five and a half million coupons will spread the word about this anniversary throughout Spain, featuring an image of the Gran Telescopio Canarias (GTC or Grantecan), the world's largest optical-infrared telescope, located at the Roque de los Muchachos Observatory (La Palma). Since it began scientific operations in 2009, the GTC has become a symbol of the scientific and technical consolidation of the IAC and the Canary Islands Observatories (OCAN), and itsAdvertised on -
It’s been decades since the need to study other stars to understand the past, present and future of the Sun was realized. One important aspect that has been investigated is the magnetic activity of stars for which we cannot fully grasp the mechanisms involved. Indeed, the origin of stellar magnetic cycles or the dependence of the magnetic activity on the stellar properties are not completely understood. This knowledge improves not only our understanding of the physics involved in stellar evolution but also affects the study of the Sun to better predict high-energy events and the betterAdvertised on
