Sensitivity of the Global 21-cm Signal to Dark Matter-Baryon Scattering
Aryan Rahimieh, Priyank Parashari, Rui An +3
With current and upcoming experiments on the horizon, the global 21-cm signal can open up new avenues for probing dark matter (DM) physics at redshifts that are otherwise inaccessi…
Fresh Look at Neutrino Self-Interactions With the Lyman- Forest: Constraints from EFT and PRIYA Simulations
Adam He, Mikhail M. Ivanov, Simeon Bird +2
We present the first search for evidence of neutrino self-interaction with two new, state-of-the-art likelihoods for eBOSS Lyman- data. These are an effective field theory (EFT…
COZMIC. III. Cosmological Zoom-in Simulations of Self-interacting Dark Matter with Suppressed Initial Conditions
Ethan O. Nadler, Rui An, Daneng Yang +3
We present eight cosmological dark matter (DM)--only zoom-in simulations of a Milky Way--like system that include suppression of the linear matter power spectrum , and/or vel…
COZMIC. II. Cosmological Zoom-in Simulations with Fractional non-CDM Initial Conditions
Rui An, Ethan O. Nadler, Andrew Benson +1
We present cosmological dark matter (DM)-only zoom-in simulations of a Milky Way analog with initial conditions appropriate for scenarios where non-cold dark matter (NCDM) is…
COZMIC. I. Cosmological Zoom-in Simulations with Initial Conditions Beyond Cold Dark Matter
Ethan O. Nadler, Rui An, Vera Gluscevic +2
We present 72 cosmological dark matter-only -body zoom-in simulations with initial conditions beyond cold, collisionless dark matter (CDM), as the first installment of the COZMI…
Bounds on Velocity-Dependent Dark Matter-Baryon Scattering from Large-Scale Structure
Adam He, Mikhail M. Ivanov, Rui An +2
We explore interacting dark matter (DM) models that allow DM and baryons to scatter off of each other with a cross section that scales with relative particle velocity. Using the ef…
