Topic: infrared observations

Elena Pinetti explores astrophysical searches for dark matter across a wide range of masses and interactions. Observations complement laboratory searches for particles such as axions and weakly interacting massive particles. The talk develops strategies that turn observatories into probes of fundamental physics, including infrared observations with JWST for axions and radio studies of cosmic filaments for WIMP scenarios.

Infrared observations expose parts of the Universe that optical surveys miss and test prevailing theories of galaxy formation. This seminar reviews questions about baryon concentrations, galaxy lifetimes, bimodality and downsizing, and the contribution of optically hidden galaxies, in the context of new images from JWST.
