Cosmic Reionization May Still Have Started Early and Ended Late: Confronting Early Onset with CMB Anisotropy and 21 cm Global Signals
Kyungjin Ahn, Paul R. Shapiro
The global history of reionization was shaped by the relative amounts of starlight released by three halo mass groups: atomic-cooling halos (ACHs) with virial temperatures Tvir > 1…
Large-scale variation in reionization history caused by Baryon-dark matter streaming velocity
Hyunbae Park, Paul R. Shapiro, Kyungjin Ahn +2
At cosmic recombination, there was supersonic relative motion between baryons and dark matter, which originated from the baryonic acoustic oscillations in the early universe. This…
HIR4: Cosmological signatures imprinted on the cross correlation between 21-cm map and galaxy clustering
Feng Shi, Yong-Seon Song, Jacobo Asorey +5
We explore the cosmological multitracer synergies between an emission line galaxy distribution from the Dark Energy Spectroscopic Instrument and a Tianlai Project 21-cm intensity m…
First Structure Formation under the Influence of Gas-Dark Matter Streaming Velocity and Density: Impact of the Baryons-trace-dark matter Approximation
Hyunbae Park, Kyungjin Ahn, Naoki Yoshida +1
The impact of the streaming between baryons and dark matter on the first structures has been actively explored by recent studies. We investigate how the key results are affected by…
HIR4: cosmology from a simulated neutral hydrogen full sky using Horizon Run 4
Jacobo Asorey, David Parkinson, Feng Shi +6
The distribution of cosmological neutral hydrogen will provide a new window into the large-scale structure of the Universe with the next generation of radio telescopes and surveys.…
