Dark Matter Constraints from Small-Scale Cosmic Structure
Ethan O. Nadler, Keir K. Rogers, Alex Drlica-Wagner
The paper reviews how observations of small‑scale cosmic structures, such as dwarf galaxies and the Lyman‑α forest, constrain the microphysical properties of dark matter models.
Strongest constraints on dark acoustic oscillations from the Lyman-alpha forest
Zhihan Yuan, Caleb Gemmell, Keir K. Rogers +4
We set the first constraints on a small-scale dark acoustic oscillation (DAO) in the linear matter power spectrum arising from dark sector interactions, with a full forward model o…
The Atacama Cosmology Telescope: Probing new signatures of ultralight axions with gravitational lensing
Alex Laguë, Keir K. Rogers, Mathew S. Madhavacheril +14
Ultralight axions (ULAs) are well-motivated dark matter particle candidates that arise in many extensions of the Standard Model of particle physics. ULAs with mass $m_\mathrm{a} \l…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Bayesian inference on Calabi--Yau moduli spaces and the axiverse: experimental data meets string theory
Mudit Jain, Elijah Sheridan, David J. E. Marsh +3
We develop tools of Bayesian inference on the moduli space of Calabi--Yau (CY) manifolds. We sample from the invariant Weil--Petersson (WP) measure using Markov Chain Monte Carlo a…
Prospects for disentangling dark matter with weak lensing
Calvin Preston, Keir K. Rogers, Alexandra Amon +1
We investigate the degeneracy between the effects of ultra-light axion dark matter and baryonic feedback in suppressing the matter power spectrum. We forecast that galaxy shear dat…
