Dr. Yuan Li (University of Michigan) Title : Thermal Instabilities, Star Formation and AGN Feedback in Cool-Core Galaxy Clusters Abstract : The feedback from active galactic nuclei (AGNs) is widely considered to be the major heating source in cool-core galaxy clusters, preventing a classical cooling flow where the intra-cluster medium (ICM) cools at hundreds to … Continue reading "CRA seminar (Dr. Yuan Li)"

Title: Constraining the origin of IceCube’s neutrinos with HAWC. Abstract: IceCube has observed an astrophysical isotropic flux of neutrinos in the 10 TeV - 8 PeV range. Though an extragalactic origin is usually assumed, no unequivocal association with astrophysical objects has been made. It is often assumed that the neutrino sources are also cosmic ray sources … Continue reading "CRA seminar (Prof. Ignacio Taboada)"
