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…
Reionization in HESTIA: Studying reionization in the LG through zoom simulations
David Attard, Luke Conaboy, Noam Libeskind +3
While cosmic reionization has been broadly constrained by global observables, the interplay between internal sources [Milky Way (MW), M31, and their satellites] and external ioniza…
Double-Peaked Ly Emission during Reionization Requires Nearby Voids and a Favorable Local Ionizing Background
Hyunbae Park, Aaron Smith, Intae Jung +11
Several Lyman-alpha (Ly) emitters deep into the reionization era exhibit double-peaked Ly emission profiles, raising the question of how the intergalactic medium can transm…
POLAR-II: modeling star formation history of galaxies on the 21-cm signal from Epoch of Reionization
Qing-Bo Ma, Raghunath Ghara, Benedetta Ciardi +6
Galaxies may suffer some starburst and quenched periods in their history due to e.g. galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (…
Exploring the effect of different cosmologies on the Epoch of Reionization 21-cm signal with POLAR
Anshuman Acharya, Qing-bo Ma, Sambit K. Giri +8
A detection of the 21-cm signal power spectrum from the Epoch of Reionization is imminent, thanks to consistent advancements from telescopes such as LOFAR, MWA, and HERA, along wit…
Dust-UV offsets in high-redshift galaxies in the Cosmic Dawn III simulation
Pierre Ocvirk, Joseph S. W. Lewis, Luke Conaboy +13
Recent observations have revealed puzzling spatial disparities between ALMA dust continuum and UV emission as seen by HST and JWST in galaxies at (e.g. ALPINE and REBELS su…
