Title:"Constraints on galaxy formation from the EDGES 21-cm detection"
Abstract:
On March 1st, the EDGES collaboration reported the detection of a sharp absorption signal in the all-sky radio spectrum at ~78 MHz. The anomalous amplitude of this signal (2x stronger than expected) has led to a variety of exotic explanations, including milli-charged dark matter and as-yet-unidentified radio backgrounds in the early Universe. I will argue that the frequency and shape of the signal (set largely by galaxy formation) are also unexpected. If confirmed, the EDGES signal may thus be evidence of new physics *and* new astrophysics.

Title:"ISCRA summer school"
Abstract:
The International school of Cosmic Ray Astrophysics (ISCRA) holds biennial courses for graduate students and young researchers that stress the inter-relationships between sub-disciplines in Astrophysics, Particle Physics and Cosmology and focus upon recent results from different specialty areas. I will talk about my experience at the school and show recent results of direct cosmic ray detection experiment.
