Speakers: Christopher Eckner (CNRS, LAPTh) Abstract:I will present three recent papers advancing our understanding of astrophysics and cosmology. The covered papers are:I)  arXiv:2304.0607: "The Image of the M87 Black Hole Reconstructed with PRIMO"   A crisper image of the supermassive black hole of M87 with machine learningII)  arXiv:2304.09895: "Anomalies in Gravitational-Lensed Images Revealing Einstein Rings Modulated by […]

Speakers: Pedro de la Torre Luque (Stockholm University)The creation of antiparticles in the Galaxy has been discussed as a potential signal of exotic production mechanisms such as primordial black hole evaporation or dark matter decay/annihilation, in addition to the more conventional production from cosmic-ray (CR) interactions. Recent CR detectors have provided very accurate measurements on […]

Speakers: Gilles Parez (CRM, Montréal)Entanglement and separability are two opposite yet intertwined notions in quantum mechanics. A quantum state is said to be entangled if it is not separable, and vice versa. Quantifying how entangled two subsystems are remains a challenging problem, which has led to important insights in the context of quantum many-body systems. […]

Speakers: Lorenz Eberhardt (Princeton, IAS)Abstract: I will explain a proposal which relates three-dimensional quantum gravity in AdS3 to a particular 3d TQFT that we refer to as ``Virasoro TQFT’'. This relation gives a precise meaning to the standard folklore that pure 3d gravity is related to two copies of SL(2,R) Chern-Simons theory. I will discuss […]
