or : DESI constraints on relative baryon-CDM perturbations
Ananda F. Smith, Mikhail M. Ivanov, Roger de Belsunce +3
We carry out a search for the relative baryon-cold dark matter (CDM) density and velocity modes in the DESI full-shape (FS) data, and investigate whether DESI's preference for evol…

Effects of magnetically driven shocks on nucleosynthesis and kilonovae from neutron star mergers
Yuan Feng, Oleg Korobkin, Elias R. Most +2
Neutron-star mergers can launch mildly relativistic to moderately relativistic outflows whose interaction with the ejecta can reshape kilonova emission. We parametrically study mag…

Cosmological constraints on anisotropic Thurston geometries
Ananda F. Smith, Craig J. Copi, Glenn D. Starkman
Much of modern cosmology relies on the Cosmological Principle, the assumption that the Universe is isotropic and homogeneous on sufficiently large scales, but it remains worthwhile…
