Blazars are the most luminous extrgalactic gamma ray sources. They are a type of Active Galactic Nuclei which are powered by material falling onto a supermassive black hole at the center of the host galaxy. They show sporadic bursts of activity with different time range. In this talk we present a 10 year data analysis of a sample of bright blazars detected by Fermi-LAT (0.1-300 GeV), in...
The main objective behind the MATHUSLA proposal is to build a large area hodoscope detector at ground level, close to the interaction point of the CMS detector, to look for the decay signals of neutral long lived particles (LLP) at the next HL-LHC runs in an environment with low background. LLPs are expected in the context of Beyond Standard Models, which try to solve open problems in...
We describe the dynamics of a quantum field coupled to a moving heat bath, in the formalism of the Markovian master equation for the field considered as an open system. We apply this to the superradiance of a rotating black hole, which provides a useful paradigm for understanding other irreversible active processes. Fermions can't superradiate, but work may be extracted from their...
