Topic: cosmic filaments

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.

This seminar examines how galaxies assemble through both the accretion of gas along cosmic filaments and mergers with other galaxies. It connects tidal interactions and coalescence to the history of star formation. The discussion compares sustained stellar growth with bursts associated with dynamical encounters.
