On a self-regulated escape of cosmic rays from sources
Friday, May 10th, 2024, 11:30am – Aula D (old SISSA building) & streaming
Abstract. The escape of accelerated particles from their sources, to become cosmic rays, is a complex and poorly understood phenomenon. Recent theoretical advances and new observations of high energy radiation from the regions around sources are shedding some light on this phenomenon, so crucial to shape the spectrum of particles that we receive at the Earth or that we infer from indirect observations. I will discuss these aspects with emphasis on self-confinement, namely the generation of electromagnetic perturbations induced by cosmic ray currents, with applications to supernova remnants, pulsar wind nebulae and sources of ultra high energy cosmic rays.

Who’s Afraid of Dark Energy?
Friday, May 17th, 2024, 11:30am – Aula D (old SISSA building) & streaming
Abstract. Cosmic acceleration dominates the behavior of the recent universe, with some fundamental new physics at its heart. Recent data gives a tantalizing suggestion that the dark energy behind it is more complicated than a cosmological constant. Nevertheless, I emphasize that there is quite a lot that we do know about how to describe dark energy behavior, and great promise for further insight from data within the next year.
