A team at the Instituto de Astrofísica de Canarias (IAC) has discovered a new case of galactic cannibalism in the neighbourhood of the Milky Way, which has caused the merging of two galaxies on the smallest scale so far known.

Scientists from all over the world who are studying high energy astrophysics met today in La Palma, after attending yesterday, at the Roque de los Muchachos, the inauguration of LST-1, the prototype of the four large sized telescopes which will be a part of the CTA North array.

Its height is 45 m, and its diameter is 23 metres; it weighs close to 100 tonnes which can be moved in less than 20 seconds to capture the gamma rays emitted by the most energetic phenomena in the universe. This is the telescope which was inaugurated this morning at the Roque de los Muchachos Observatory, in the La Palma town of Garafia by the Nobel Laureate in Physics Takaaki Kajita, and by the Spanish minister Pedro Duque, among other outstanding scientific and political figures.

The prototype of the four large size telescopes which will be a part of the CTA North network, referred to as LST-1, will be inaugurated at the Roque de los Muchachos Observatory on October 10th . The ceremony will be attended by political authorities, and the highest level representatives of scientific insituttions in Japan, Germany, and Spain, the main countries involved in its construction.

An international team of researchers, including David S. Aguado, Jonay González and Carlos Allende Prieto of the Instituto de Astrofísica de Canarias (IAC), has found a star with extremely low metallicyt, one of the oldest in the Milky Way, and for that reason an excellent messenger from the early universe.

The “Observatorio de las Energías Renovables y la Eficiencia Energética” Foundation is organizing on October 4th, a seminar with this title at the headquarters of the Real Sociedad Económica de Amigos del País de Tenerife. The Instituto de Astrofísica de Canarias will participate in this set of lectures, with talks by Antonia María Varela Pérez and Federico de la Paz.
