Astroparticle Physics studies particles from the cosmos in order to investigate both. The "Valencia Experimental Group of Astroparticles" (VEGA) of the IFIC participates in the neutrino telescopes ANTARES and KM3NeT. The first is installed at a depth of 2500 meters at the bottom of the Mediterranean sea off the coast near Toulon in France and has been operating from 2008 to 2022. The second, KM3NeT, is also being deployed in the Mediterranean and will have an effective volume of detection of several cubic kilometres.
