Snowmass2021 Computational Frontier White Paper: Cosmological Simulations and Modeling
Marcelo A. Alvarez, Arka Banerjee, Simon Birrer +9
Powerful new observational facilities will come online over the next decade, enabling a number of discovery opportunities in the "Cosmic Frontier", which targets understanding of t…
The impact of inhomogeneous subgrid clumping on cosmic reionization II: modelling stochasticity
Michele Bianco, Ilian T. Iliev, Kyungjin Ahn +4
Small-scale density fluctuations can significantly affect reionization but are typically modelled quite crudely. Unresolved fluctuations in numerical simulations and analytical cal…
Cosmological Information from the Small-scale Redshift Space Distortions
Motonari Tonegawa, Changbom Park, Yi Zheng +4
The redshift-space distortion (RSD) in the observed distribution of galaxies is known as a powerful probe of cosmology. Observations of large-scale RSD have given tight constraints…
Cosmological constraints from the redshift dependence of the Alcock-Paczynski effect: Possibility of estimateing the non-linear systematics using fast simulations
Qinglin Ma, Yiqing Guo, Xiao-Dong Li +5
The tomographic AP method is so far the best method in separating the Alcock-Paczynski (AP) signal from the redshift space distortion (RSD) effects and deriving powerful constraint…
The impact of inhomogeneous subgrid clumping on cosmic reionization
Yi Mao, Jun Koda, Paul R. Shapiro +5
Cosmic reionization was driven by the imbalance between early sources and sinks of ionizing radiation, both of which were dominated by small-scale structure and are thus usually tr…
Alcock-Paczynski Test with the Evolution of Redshift-Space Galaxy Clustering Anisotropy
Hyunbae Park, Changbom Park, Cristiano G. Sabiu +5
We develop an improved Alcock-Paczynski (AP) test method that uses the redshift-space two-point correlation function (2pCF) of galaxies. Cosmological constraints can be obtained by…
