Speakers: Claudio Toni We study the implications of the observed excess at Belle-II under the assumption of Rank-One Flavour Violation, i.e. that New Physics couples to a single specific direction […]

Speakers: Marco Bonici (INAF-IASF Milano) The analysis of galaxy clustering measurements from surveys like Euclid or DESI is likely to be affected by the so-called projection effects, which causes the […]

Speakers: Richard Taillet (Université de Savoie/LAPTH) L'hypothèse d'un univers héliocentrique formulée par Nicolas Copernic en 1543, en opposition au modèle géocentrique dit « de Ptolémée » et en vigueur depuis […]

Speakers: Zucheng Gao Parity-violating has been found in the weak interactions. In cosmology, certain inflation mechanism can also introduce parity-violating imprints on the primordial fluctuations. Here we present theoretically how […]

Speakers: Daniele Oriti (Universidad Complutense de Madrid) . Abstract: We show how a cosmological dynamics with a late-time cosmic acceleration and an asymptotic deSitter regime can be obtained from hydrodynamics on […]

Speakers: Clément Delcamp (IHES) Defining internal symmetry in a quantum theory through the lens of topological defects has opened the door to generalised notions of symmetry. In this seminar, I […]

Speakers: Jiamin HOU (Max Planck Institute for Extraterrestrial Physics (MPE)) Galaxy N-point function statistics provide a powerful tool for extracting non-Gaussian information. To efficiently compute N-point functions, various approaches have […]

Speakers: Yann Gouttenoire (Tel Aviv University) Abstract: In order to explain the large amplitude of the nano-Hertz stochastic gravitational wave background observed in pulsar timing arrays (PTA), primordial sources must […]
