When galaxies burst II. Implications of enhanced burstiness for the 21-cm Cosmic Dawn signal
Hovav Lazare, Sarah Libanore, Eleonora Vanzan +2
Recent JWST observations suggest that star formation in the early universe was substantially burstier than assumed in standard models. Such burstiness can be described as a stochas…
The Rise and Fall of Acoustic Oscillations at Cosmic Dawn
Hector Afonso G. Cruz, Gabriele Montefalcone, Julian B. Muñoz +2
Cosmic dawn 21-cm observations will extend standard-ruler cosmology into the first billion years, unlocking epochs inaccessible by the cosmic microwave background and large-scale s…
High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization
Rennan Barkana, Oliver Basquette, Ankita Bera +22
In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…
Overview of 21cm Experiments at high redshift with SKAO
CD Science Working Group, Gianni Bernardi, Daniela Breitman +81
We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…
An Improved Fit for Linear Halo Bias at High Redshift
Kuan Wang, Julian B. Muñoz, L. Y. Aaron Yung
High- to ultrahigh-redshift clustering of halos provides a powerful tool to understand cosmology and galaxy formation. However, theoretical predictions are not firmly established i…
Enhancing Lyα Emitter Identification in HETDEX with a Convolutional Neural Network
Shiro Mukae, Erin Mentuch Cooper, Karl Gebhardt +9
We present a deep learning framework to enhance the identification of Ly emitters (LAEs) in the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), an untargeted spectroscop…
Reionization Bubbles from Real-Space Cross Correlations of Line Intensity Maps
Emilie Thélie, Sarah Libanore, Yonatan Sklansky +2
We propose a new way to reconstruct the ionized-bubble size distribution during the Epoch of Reionization (EoR) through the real-space cross-correlation of 21-cm and star-forming l…
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…
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…
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…
