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…
Halo mass functions in mixed cold and fuzzy dark matter models
Sarah C. Johnston, Simon May, Tibor Dome +5
We investigate the impact of mixed cold and fuzzy dark matter (MDM) cosmologies on the halo mass function (HMF) using numerical simulations performed with the AxiREPO framework. We…
The Impact of Fuzzy Dark Matter Dynamics on the Accumulation and Fragmentation of Primordial Gas
Alexander Tocher, Anastasia Fialkov, Simon May +4
Fuzzy Dark Matter (FDM), particularly in the eV mass regime is frequently used to characterize wave-like interference effects. It exhibits macroscopic wave properties, w…
Impact of Stochastic Pop~III X-ray Binaries on the Cosmological 21-cm Signal
Saswata Dasgupta, Boyuan Liu, Anastasia Fialkov +3
High-mass X-ray binaries are one of the primary drivers of the 21-cm signal from Cosmic Dawn and Reionization, playing a leading role in the thermal history of the intergalactic me…
The effect of photon re-scattering due to cosmic reionization on 21-cm images and power spectra
Sudipta Sikder, Rennan Barkana, Anastasia Fialkov
The 21-cm signal from neutral hydrogen serves as a critical tool for unraveling the astrophysical processes that shaped cosmic dawn and the epoch of reionization. We explore the us…
Ultraviolet photon production rates of the first stars: Impact on the He II 1640 Å emission line from primordial star clusters and the 21-cm signal from cosmic dawn
Joel Wasserman, Erik Zackrisson, Jiten Dhandha +3
The first stars, the chemically pristine Population III, likely played an important role in heating the intergalactic medium during the epoch of cosmic dawn. The very high effectiv…
