First Results from HERA Phase II
The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83
We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…
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…
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…
An Alcock-Paczynski Test on Reionization Bubbles for Cosmology
Emilie Thélie, Franco Del Balso, Julian B. Muñoz +1
In this paper, we propose an Alcock-Paczyński (AP) test to constrain cosmology using HII bubbles during the Epoch of Reionization. Similarly to cosmic voids, a stack of HII bubbles…
