All research included in the CTA-Spain Consortium and CIEMAT members participating in AMS and those involved in the MAGIC Collaboration.


The members of the Particle Astrophysics Group of the IAC participate actively in three large international collaborations of high-energy astrophysics: AMS (Alpha Magnetic Spectrometer), the Cherenkov radiation telescopes MAGIC I and II, and the Cherenkov Telescope Array (CTA). AMS is a particle detector designed to operate in space, on-board the International Space Station. It was successfully installed on the station on May 2011, and will operate during its lifetime. It is aimed at carrying out a high precision and high statistics study of the spectrum and composition of primary cosmic rays within a wide range of energies, as well as to look for primordial antimatter and dark matter in an indirect way.

The MAGIC Collaboration is integrated by 20 research institutes and university departments from Armenia, Bulgaria, Finland, Germany, Italy, Poland, Spain, Switzerland and USA. The collaboration comprises two 17m diameter telescopes, located at the Roque de los Muchachos Observatory, designed to measure the Cherenkov radiation associated with atmospheric showers from very high-energy gamma rays.

CTA is a major international collaboration for building two large Cherenkov observatories at North and South Hemispheres. Roque de los Muchachos Observatory in La Palma has been selected to host the Northern observatory. Its construction has begun in 2016.


This has been a very important year for the implementation of the Northern observatory of the Cherenkov Telescope Array (CTA) at the Roque de los Muchachos Observatory (ORM). One side, the IAC signed a collaboration agreement in April with the Institute for Cosmic Ray Research of the University of Tokyo. Its Director is Prof. Takaaki Kajita, Nobel Prize awardee in 2015, and the agreement was made for the joint installation and funding of the four large size telescopes (23m) of CTA. Furthermore, the Director the IAC, Prof. Rafael Rebolo, signed in September the agreement with the CTA Observatory (CTAO, the public enterprise in charge of deploying CTA) to allow the IAC to locate all CTA-North  telescopes at the ORM under the umbrella of CTAO: 4 large-size and 15 medium-size (12m) telescopes.

With respect to the AMS collaboration, two main papers were published in Physical Review Letters, one of the corresponding to the results obtained during the PhD thesis of Dr. Rosa Clavero, defended at the University of La Laguna in 2014.
