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 […]

Title: Cosmological Magnetic Fields from Ultralight Dark Matter Speaker: Robert Brandenberger (McGill) Venue&Time: Red Room / 15:00 Abstract: A coherently oscillating ultralight dark matter field which couples to electromagnetism in the same way as an axion induces a tachyonic instability which leads to the generation of cosmological magnetic fields immediately after the time of recombination. […]

Title; 'Effective Field Theory for Thermal Phase transitions' Speaker: Mikael Chala (Granada) Venue&Time: Red Room / 15:00 Abstract: I will present recent progress in applying effective field theory (EFT) to the precise computation of thermal phase transition parameters and the associated gravitational wave spectra. I will also briefly comment on byproducts of this work, including […]
