Description
Atomic dark matter (ADM) is a simple extension to the Standard Model that is motivated by considerations in both particle and astrophysics. ADM can alter structure formation on a variety of astrophysical scales due to the presence of dark baryon acoustic oscillations, and its ability to dissipate energy through cooling mechanisms. While previous work has begun to constrain the ADM parameter space using cosmological observations and late time galactic simulations, the intermediate redshifts are largely unexplored. In this talk I present ongoing work investigating how ADM could be probed and constrained from Lyman Alpha forest observations, utilising cosmological hydrodynamical simulations of the ADM.
