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…
Primordial Magnetic Fields at Cosmic Dawn: 21-cm Forecasts with HERA and SKA
Keduse Worku, Hector Afonso G. Cruz, Marc Kamionkowski
Primordial magnetic fields (PMFs) can enhance the abundance of low-mass halos during Cosmic Dawn by sourcing additional small-scale matter fluctuations. This enhanced small-scale p…
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…
The First Billion Years in Seconds: An Effective Model for the 21-cm Signal with Population III Stars
Hector Afonso G. Cruz, Julian B. Munoz, Nashwan Sabti +1
Observations of the 21-cm signal are opening a window to the cosmic-dawn epoch, when the first stars formed. These observations are usually interpreted with semi-numerical or hydro…
