Speaker: Cristina Puchades Ibáñez (University of Mainz) Venue & Time: Red Room / 15:00 Abstract: We explore the dynamics of cosmological phase transitions in a dark sector model featuring a dark photon associated with a U(1)D gauge symmetry and radiative symmetry breaking. Our analysis focuses on different approaches to construct the effective potential: the high-temperature […]

Speaker: Piotr Toczek (Warsaw University) Venue & Time: 15:00 / Red Room Abstract: Primordial black holes, hypothetical objects that may have formed in the early Universe through the interplay between high-energy physics and gravity, are very appealing candidates for dark matter. In this seminar, I will discuss their formation as a result of the collapse of […]

Madrid's Polygonal Gravity Seminar Series Wednesday, January 29th. Blue Room (IFT) 11:30h First talk Speaker: Robie Hennigar (U. Durham, UK) Title: Building Regular Black Holes Abstract: The study of regular (singularity-free) black holes has a long history, but progress has been limited by the absence of a dynamical framework in which they form and by […]
