Forecasting 21-cm power spectrum sensitivity to dark Matter-baryon scattering
Aryan Rahimieh, Priyank Parashari, Vera Gluscevic
We explore the potential of upcoming 21-cm interferometric observations to probe interacting dark matter (IDM). We focus on scenarios where the dark matter-baryon scattering cross-…
The Effects of Linear Matter Power Spectrum Enhancement on Dark Matter Substructure
Ethan O. Nadler, Vera Gluscevic, Andrew Benson
We present cosmological dark matter (DM)--only zoom-in simulations of a Milky Way analog originating from enhanced linear matter power spectra relative to the standard cold,…
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…
N-body simulations of dark matter-baryon interactions
Moritz S. Fischer, Klaus Dolag, Mathias Garny +3
Dark matter (DM) particles can interact with particles of the standard model. Although there are a number of constraints derived from direct and indirect detection experiments, the…
The Atacama Cosmology Telescope: DR6 Maps
Sigurd Naess, Yilun Guan, Adriaan J. Duivenvoorden +163
We present Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) maps of the Cosmic Microwave Background temperature and polarization anisotropy at arcminute resolution over three…
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)…
