The APPEC Town Meeting will take place on Sep 23–24, 2025, at the Centro de Astropartículas y Física de Altas Energías (CAPA) of the Universidad de Zaragoza, Spain. As preparation for the next roadmap, a community survey was conducted earlier this year, and a briefing book covering all Astroparticle Physics topics will be published this […]
Searching for sub-GeV particle dark matter with Spherical Proportional Counters The NEWS-G collaboration is searching for light dark matter using spherical proportional counters. Access to 50 MeV to 10 GeV mass range is enabled by the combination of single electron threshold, light gaseous targets (H, He, Ne), and highly radio-pure detector construction. Most recently, new
A study by the Center for Astroparticles and High Energy Physics (CAPA-Unizar) establishes the most restrictive limit, refuting the signal from the DAMA/LIBRA experiment, the only one to date that claims to have detected a signal from galactic dark matter. The new, highly significant result, published in Physical Review Letters, represents the culmination of two
The Governing Council of the University of Zaragoza has definitively approved the creation of the Center for Astroparticles and High Energies (CAPA), as well as its internal regulations. The fundamental objective of the University Research Institute Center for Astroparticles and High Energy Physics is to promote research in the fields of high-energy physics, nuclear and
The DarkQuantum project, coordinated from the Center for Astroparticles and High Energy Physics (CAPA) at the University of Zaragoza, was recently featured in the Tercer Milenio science section of the newspaper Heraldo de Aragón. The article highlights the project’s innovative approach, combining quantum technologies and particle physics to tackle one of the greatest mysteries of
Ultra-high-energy cosmic messengers Rafael Alves Batista is a Professor at the Institut d’Astrophysique de Paris at the Sorbonne Université (France) Website: https://www.8rafael.com/en/ Abstract: The origins of the most energetic particles in the Universe have been a long-standing puzzle. In the quest to identify their sources, it is crucial to understand how
DESI-Y1: New light on the dark Universe Eusebio Sánchez, Scientific researcher at CIEMAT, PI of the Cosmology Group Abstract: The beginning of the 21st century brought the development and confirmation of the standard model of cosmology, LCDM. The Universe is made of a 70% of dark energy in the form of a cosmological constant, a
