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…
JWST constraints on the UV luminosity density at cosmic dawn: implications for 21-cm cosmology
Sultan Hassan, Christopher C. Lovell, Piero Madau +10
An unprecedented array of new observational capabilities are starting to yield key constraints on models of the epoch of first light in the Universe. In this Letter we discuss the…
Relative baryon-dark matter velocities in cosmological zoom simulations
Luke Conaboy, Ilian T. Iliev, Anastasia Fialkov +2
Supersonic relative motion between baryons and dark matter due to the decoupling of baryons from the primordial plasma after recombination affects the growth of the first small-sca…
Redshift-space distortions in simulations of the 21-cm signal from the cosmic dawn
Hannah E. Ross, Sambit K. Giri, Keri L. Dixon +3
The 21-cm signal from the Cosmic Dawn (CD) is likely to contain large fluctuations, with the most extreme astrophysical models on the verge of being ruled out by observations from…
Predictions for measuring the 21-cm multi-frequency angular power spectrum using SKA-Low
Rajesh Mondal, Abinash Kumar Shaw, Ilian T. Iliev +5
The light-cone (LC) effect causes the mean as well as the statistical properties of the redshifted 21-cm signal to change with frequency (or cosmic t…
The 21cm bispectrum as a probe of non-Gaussianities due to X-ray heating
Catherine A. Watkinson, Sambit K. Giri, Hannah E. Ross +4
We present analysis of the normalised 21-cm bispectrum from fully-numerical simulations of intergalactic-medium heating by stellar sources and high-mass X-ray binaries (HMXB) durin…
