A team from the Instituto de Astrofísica de Canarias (IAC) has quantified for the first time the impact that the motions of binary stars can have on estimates of dark matter in some of the smallest galaxies in the universe. The study proposes a new methodology that will make it possible to obtain more precise measurements of the amount of dark matter present in these systems. The Milky Way, our galaxy, contains hundreds of billions of stars. However, dozens of much smaller galaxies orbit around it, dwarf companions that host thousands of times fewer stars and live embedded within our galaxy

El experimento, desarrollado en el Instituto de Astrofísica de Canarias (IAC) e impulsado por un investigador del network del proyecto europeo UNDARK, recibe el respaldo de un comité internacional para construir un detector de nueva generación destinado a la búsqueda directa de materia oscura de alta frecuencia. El experimento DALI , liderado por Javier de Miguel, ha superado con éxito el Preliminary Design Review (PDR), una evaluación internacional que certifica la madurez científica y tecnológica del proyecto. Tras esta revisión, un comité independiente de expertos ha recomendado avanzar

The Instituto de Astrofísica de Canarias (IAC) has successfully completed a technological milestone of great significance: the “Redundancy of the RedIRIS Tenerife–La Palma Maritime and Terrestrial Optical Network” project. This new and robust optical communications network guarantees the continuity of the data highways for the Canary Islands’ observatories — the Teide Observatory (OT) in Tenerife and the Roque de los Muchachos Observatory (ORM) in La Palma — ensuring their connectivity in the event of any technical or environmental contingency. This achievement is the result of a joint
