HECAP Seminar by Ranjan Laha - Searching for Dark Matter Using Two Different Observables: JWST UV Luminosity Function Measurements and Very-High-Energy Gamma-Ray Observations by Tibet AS_\gamma and LHAASO

Abstract
Searching for non-gravitational interactions of dark matter in one of the major research areas in science. In this talk, I will describe two different ways to discover the nature of dark matter.
In the first part of my talk, I will discuss how one can use the UV luminosity function measurements to derive leading constraints on dark matter - baryon scattering. These constraints will further improve as JWST discovers more distant galaxies.
In the second part of my talk, I will discuss the discovery of high-energy diffuse gamma-rays by the Tibet AS_\gamma and LHAASO collaborations help us in deriving some of the most stringent constraints on dark matter decay life-time.
