Title: 'Asymmetric Dark Matter induced by Baryogenesis' Speaker: Miguel Escudero (CERN) Venue&Time: Red Room / 15:00 Abstract: We live in a Universe where structures are made out of baryons but not of antibaryons. Could the dark matter be made of particles and not antiparticles? This is an old question and many asymmetric dark matter scenarios […]

Speaker: Shunsuke Neda (ICRR, Univ. of Tokyo) Venue & Time: Red Room / 15:00 Title: Primordial black holes from Q-balls Abstract:  We discuss primordial black holes (PBHs) originating from Q-balls, which are non-topological solitons arising in complex scalar field theories with a global U(1) symmetry. Depending on the cosmic expansion history, Q-balls can source PBH formation in […]

Gravity, Supergravity and Superstrings (GRASS) Seminar Speaker: David Pereñiguez (Johns Hopkins U.) Title: 'Gravitational Duality at the Lightring, QNM isospectrality, and Ringdown Nonlinearities from Penrose Limits' Abstract: At high frequencies, the physics near a black hole’s lightring can be captured by Penrose-limit plane waves adapted to the photon sphere. In this talk, I will solve […]

Title: 'Sub-PeV gamma-ray astronomy and its physics' Speaker: Sei Kato (Sorbonne Université, Institut d'Astrophysique de Paris) Venue&Time: Red Room / 15:00 Abstract: This talk will focus on the physics that can be explored with sub-PeV gamma-ray astronomy (E > 10^14 eV), particularly on the Galactic diffuse gamma rays and the dark matter. Also, our project […]

Title: 'The tensions of LCDM: An update of observations and theoretical implications' Speaker: Leandros Perivolaropoulos (Ioannina) Venue&Time: Red Room / 15:00 Abstract: The standard LCDM cosmological model, despite its success in describing the large-scale structure of the Universe, is currently challenged by statistically significant discrepancies between early and late-universe observations. In this talk, I provide […]
