General
El Grupo de Astrofísica de Partículas del IAC participa activamente en tres grandes colaboraciones internacionales de astrofísica de muy altas energías: AMS (Alpha Magnetic Spectrometer), los telescopios de radiación Cherenkov MAGIC I y II, y el Cherenkov Telescope Array (CTA).
AMS es un detector de partículas diseñado para operar en el espacio, a bordo de la Estación Espacial Internacional. Se instaló con éxito en mayo de 2011, y se espera que opere durante toda la vida útil de la misma. Su misión es realizar un estudio de alta precisión y estadística del espectro y la composición de los rayos cósmicos primarios en un amplio rango de energía, así como buscar antimateria primordial y materia oscura de forma indirecta.
La colaboración MAGIC está formada por 20 institutos y departamentos universitarios de Alemania, Armenia, Bulgaria, España, EEUU, Finlandia, Italia, Polonia y Suiza. La colaboración cuenta con dos telescopios de 17 m de diámetro localizados en el Obsevatorio del Roque de los Muchachos, diseñados para medir la radiación Cherenkov asociada a cascadas atmosféricas producidas por rayos gamma de muy alta energía y localizados en el Observatorio del Roque de los Muchachos.
Además de esto, y también en el marco de la observación de rayos gamma de muy alta energia, el IAC participa en la colaboración internacional CTA, cuyo objetivo es construir dos grandes complejos de observación en los hemisferios Norte y Sur. El Observatorio del Roque de los Muchachos, en La Palma, ha sido seleccionado para albergar el observatorio Norte. El primer telescopio de gran diámetro fue inaugurado en octubre de 2018 y actualmente estamos en la fase de construcción de otros tres.

Constraining cosmic rays and magnetic fields in the Perseus galaxy cluster with TeV observations by the MAGIC telescopesGalaxy clusters are being assembled today in the most energetic phase of hierarchical structure formation which manifests itself in powerful shocks that contribute to a substantial energy density of cosmic rays (CRs). Hence, clusters are expected to be luminous gamma-ray emitters since they also act as energy reservoirs for additional CR sourcesAleksić, J. et al.
