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, […]
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
Jorge Sanz Forcada, Investigador Científico en el Centro de Astrobiología, del INTA-CSIC Abstract: Currently known extrasolar planets population is biased towards short-period planets. They tend to be highly irradiated. Photons in the XUV range (1-912 A) are of special importance in this context because they ionize neutral H atoms, yielding planetary atmosphere photoevaporation, which in
Multimessenger physics, gravitational waves and quantum gravity Lecturer: Antonia Micol Frassino (University of Alcalá & ICC University of Barcelona) Abstract: Potential experimental signatures of the quantum nature of gravity are becoming a thriving field with a multitude of approaches in different directions. In this talk I will first overview the contribution of gravitational waves to multimessenger
