20191209 Dec. 9, 2019, 2:00 pm Early-Universe Simulations of the Cosmological Axion Malte Buschmann, University of Michigan Abstract: Ultracompact dark matter (DM) minihalos at masses at and below 10^−12 solar masses arise in axion DM models where the Peccei-Quinn (PQ) symmetry is broken after inflation. The minihalos arise from density perturbations that are generated from the non-trivial axion self interactions during and shortly after the collapse of the axion-string and domain-wall network....

20191216 Dec. 16, 2019, 2:00 pm Particle Acceleration in the Cygnus Star Forming Region Binita Hona, Michigan Technological University Massive stars were postulated as sources of cosmic rays (CRs) in our Galaxy since more than three decades ago. GeV photons have been observed by Fermi-LAT from the star-forming region of Cygnus X, showing that young CRs up to TeV are produced and are interacting with the ambient gas and radiation fields. However, the role... More »
