Explore new frontiers in constraining dark matter microphysics through a 22-minute conference talk by Sownak Bose from ICC Durham. Recorded at the Kavli Institute for Theoretical Physics as part of the "Cosmic Signals of Dark Matter Physics: New Synergies" conference, delve into the latest developments in theory, cosmological simulations, and observational capabilities that have expanded the landscape for dark matter discovery. Learn about models that can only be tested through astrophysical and cosmological probes, and gain insights into the ongoing efforts to extract dark matter physics from cosmic observables. Understand the conference's goals of synthesizing theoretical, computational, and observational efforts while identifying new synergies between particle and cosmology theorists, simulators, and astronomers working to unravel the elusive nature of dark matter.
