First galaxy ultraviolet luminosity function limits on dark matter-proton scattering
Hovav Lazare, Ely D. Kovetz, Kimberly K. Boddy +1
Scattering between dark matter (DM) and protons leads to suppressed small-scale fluctuations, with implications for a variety of cosmological observables. In this work, we search f…
Tracing the Neutrino-Induced Phase Shift in the 21-cm Spectrum
Gabriele Montefalcone, Hector Afonso G. Cruz, Julian B. Munoz +2
We study the phase shift that free-streaming neutrinos imprint on the 21-cm power spectrum during cosmic dawn, computing for the first time its effect on both density- and velocity…
A New Boundary Condition on Reionization
Sarah Libanore, Ely D. Kovetz, Julian B. Munoz +2
The epoch of reionization (EoR) marks the last phase transition of hydrogen in our Universe, as it evolves from cold and neutral to hot and ionized in the intergalactic medium (IGM…
oLIMpus: An Effective Model for Line Intensity Mapping Auto- and Cross- Power Spectra in Cosmic Dawn and Reionization
Sarah Libanore, Julian B. Munoz, Ely D. Kovetz
Line-intensity mapping (LIM) is emerging as a powerful probe of the high-redshift Universe, with a growing number of LIM experiments targeting various spectral lines deep into the…
Joint 21-cm and CMB Forecasts for Constraining Self-Interacting Massive Neutrinos
Sarah Libanore, Subhajit Ghosh, Ely D. Kovetz +2
Self-interacting neutrinos provide an intriguing extension to the Standard Model, motivated by both particle physics and cosmology. Recent cosmological analyses suggest a bimodal p…
Neutrino Mass Constraints from kSZ Tomography
Avery J. Tishue, Selim C. Hotinli, Peter Adshead +2
We forecast neutrino mass constraints using Stage IV CMB and large-scale structure surveys, focusing on kSZ tomography as an independent probe of the growth of cosmic structure. We…
