  • Professor Norbert Langer is currently head of the Stellar Physics Group at the Argelander-Institut für Astronomie (Bonn, Germany). Considered one of the world’s leading experts in the field of theoretical stellar Astrophysics, for more than three decades he has been researching the evolution of high mass, from their early stages to the point when they explode as supernovae. These stars play an important role in the evolution of their host galaxies. However, their short lifetime makes them very difficult to observe, raising many questions about their nature. A correct interpretation of the

  • For astronomers one of the biggest obstacles is the darkness of the Universe itself, above all the darkness caused by the gas and dust which surround active galactic nuclei, or AGN. These nuclei emit a huge quantity of energy produced by the supermassive black hole onto which matter falls at a considerable rate. The accretion processes are fundamental for the evolution of active galaxies. However these nuclei often remain hidden by the dusty structures, called tori, which surround the central black hole. Studyuing the properties of this circumnuclear dust, the accretion processes, and

  • Cuando era una niña, Caitlin Casey acudía al planetario de su escuela con mucha frecuencia, fascinada por los objetos celestes que allí podía descubrir. Años después, ya como profesora de Astronomía en la Universidad de Texas, Austin (EEUU), confiesa que su pasión por esta ciencia nació en esa época y hoy disfruta enseñándola e investigando sus temas predilectos: las galaxias más masivas y luminosas del Universo, unos objetos tan extremos y complejos que suponen un reto a la hora de hacer simulaciones cosmológicas. Utilizando observaciones submilimétricas, se propone conocer cómo estas

  • Hoy se inauguró la XXIX Escuela de Invierno que, como cada año, organiza el Instituto de Astrofísica de Canarias (IAC). Por este motivo, entrevistamos a Artemio Herrero, catedrático de la Universidad de La Laguna (ULL) e investigador del IAC, especializado en las atmósferas de las estrellas masivas, que hablará sobre los Fundamentos Físicos del Transporte Radiativo. En sus charlas introducirá algunos conceptos básicos sobre la interacción entre radiación y materia que serán desarrollados por el resto de profesores a lo largo de la semana. "El transporte radiativo es fundamental en

  • Life, as we know it, exists only on Earth. The emergence of life here may be a matter of probability or luck, but in Science there is no place for the second. Evidence is needed and, for this reason, there are researchers like Malcolm Fridlund, an expert on Astrobiology and Exoplanets, bent on finding other earths that can host some form of life, however simple it may be. Professor at the University of Leiden (Netherlands) and Affiliated Professor at the Chalmers Technical University in Gothenburg (Sweden), he has been involved in instrumental development and space missions of ESA and NASA

  • “The stellar population group at IAC has developed state-of-the-art population synthesis tools for retrieving the Stellar Formation History of resolved stellar systems”“We still lack of a clear understanding of how globular clusters formed and what was the sequence of events that leaded to the formation of distinct stellar sub-populations” “The discovery of multiple stellar populations in Galactic Globular Clusters (GGCs) is one of the most important discovery of Astrophysics of last decade” By Elena Mora (IAC) Is it possible to know how stars formed billions of years ago?
