An emulator for the ionizing photon mean free path in ultra-high resolution simulations: the implications of mean free path measurements for the reionization history

Hurum Maksora Tohfa, Christopher Cain, Matthew McQuinn +1

Measurements of the mean free path of ionizing photons from high-redshift quasar spectra at - constrain the reionization history, but interpreting them requires modeli…

Dark winds on the horizon: Prospects for detecting neutrino and hot dark matter wakes in large-scale structure

Caio B. de S. Nascimento, Marilena Loverde

We explore the cosmological signatures of neutrino and Hot Dark Matter (HDM) wakes, which refers to the preferential accumulation of neutrinos (or, more broadly, HDM particles) dow…

Using Neural Emulators and Hamiltonian Monte Carlo to constrain the Epoch of Reionization's History with the Ly Forest Power Spectrum

Diego González-Hernández, Caitlin Doughty, Molly Wolfson +2

The Lyman-alpha (Ly) forest at offers a primary probe to constrain the history of the Epoch of Reionization (EoR), retaining thermal and ionization signatures imprint…

The Dark Energy Camera All Data Everywhere cosmic shear project V: Constraints on cosmology and astrophysics from 270 million galaxies across 13,000 deg of the sky

D. Anbajagane, C. Chang, A. Drlica-Wagner +78

We present constraints on models of cosmology and astrophysics using cosmic shear data vectors from three datasets: the northern and southern Galactic cap of the Dark Energy Camera…

Abundance and properties of dark radiation from the cosmic microwave background

Murali M. Saravanan, Thejs Brinckmann, Marilena Loverde +1

We study the cosmological signatures of new light relics that are collisionless like standard neutrinos or are strongly interacting. We provide a simple and succinct rephrasing of…

Kiloparsec-scale turbulence driven by reionization may grow intergalactic magnetic fields

Christopher Cain, Matthew McQuinn, Evan Scannapieco +2

The intergalactic medium (IGM) underwent intense heating that resulted in pressure disequilibrium in the wake of ionization fronts during cosmic reionization. The dynamical relaxat…
