Title: Big bang nucleosynthesis as a probe of new physics Abstract: The remarkable agreement between the observed light-element abundances and the predictions of big bang nucleosynthesis (BBN) makes BBN a powerful probe of physics beyond the Standard Model (BSM). In this talk, I will present the BBN constraints on a specific BSM particle, the Majoron, […]

Pérez Torres (Investigador científico del IAA-CSIC ) Abstract: In this talk, I trace the evolution of radio astronomy from its origins in the 1930s to the new
The 2025 RENATA meeting will take place on September 22, 2025, in Zaragoza. Its main goal is to discuss and coordinate the Spanish strategy ahead of the upcoming APPEC Strategic Roadmap 2027–2036 for astroparticle physics. The APPEC roadmap kickoff meeting will follow in Zaragoza on September 23–24 (event link). This gathering will bring together Spanish
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
Carlos Pobes is a Senior Scientist, Institute of Nanoscience and Materials of Aragon (INMA, CSIC – UNIZAR) Abstract: In this seminar, we will learn about the peculiarities of a large facility, the Amundsen-Scott scientific base at the South Pole, and then explore one of the unique experiments installed there, the IceCube neutrino telescope. We will
Iván Coarasa, member of CAPA and part of the ANAIS research team, has presented today the preliminary results on annual modulation corresponding to 6 years of data of ANAIS-112 at the IDM 2024 conference in L’Aquila (Italy). ANAIS-112 sees no modulation. Sensitivity to DAMA/LIBRA above 4 sigma level has been achieved and the best fit
First meeting of the AstroHEP Complementary Plans Around 100 astrophysicists and particle physicists will meet from June 5 to 7, 2024 at the University of Zaragoza to discuss the current state of research and advances in the different areas of the Complementary Plans for Astrophysics and High Energy Physics . Aragón participates in these plans
