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…
