Alternative dark matter models in the context of galaxy formation
Abstract: In this talk, I will briefly review the motivation & history of studying dark matter (DM) models alternative to WIMP-like CDM, and introduce our recent studies of some physically well-motivated models that are less explored in the astrophysical context. These include i) hidden-sector DM models with dissipative self-interactions; ii) the post-inflationary QCD axions. In the second half of the talk, I’ll bring the attention to studying alternative DM in regimes, where we expect significant improvements in understanding relevant baryonic astrophysical processes from a combination of observational and theoretical developments in the next decade.
Bio: I am a 5th-year PhD candidate in Physics at the California Institute of Technology, working with Prof. Philip Hopkins. I am an active member of the FIRE collaboration. My primary research interest is studying galaxy formation & evolution in dark matter models alternative to the classical CDM, using a combination of semi-analytical models and numeric simulations. During the early years of my PhD, I worked on an observational determination of the bolometric quasar luminosity functions and a series of work on high-redshift galaxy predictions from the IllustrisTNG simulation.
