Lyα forest bounds on sterile neutrino production via neutrino self-interactions
Priyank Parashari, Vera Gluscevic, Yue Zhang +3
Sterile neutrinos in the keV mass range have long been considered a well-motivated dark matter (DM) candidate. In this work, we explore a sterile neutrino production mechanism thro…
The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
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)…
The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models
Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…
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…
Self-Interacting Neutrinos in Light of Large-Scale Structure Data
Adam He, Rui An, Mikhail M. Ivanov +1
We explore a self-interacting neutrino cosmology in which neutrinos experience a delayed onset of free-streaming. We use the effective field theory of large-scale structure (LSS) t…
Tension in the Context of Dark Matter-Baryon Scattering
Adam He, Mikhail M. Ivanov, Rui An +1
We explore an interacting dark matter (IDM) model that allows for a fraction of dark matter (DM) to undergo velocity-independent scattering with baryons. In this scenario, structur…
