N-body simulations of gravitational redshifts and other relativistic distortions of galaxy clustering
Hongyu Zhu, Shadab Alam, Rupert A. C. Croft +2
Large redshift surveys of galaxies and clusters are providing the first opportunities to search for distortions in the observed pattern of large-scale structure due to such effects…
Relativistic Effects on Galaxy Redshift Samples due to Target Selection
Shadab Alam, Rupert A. C. Croft, Shirley Ho +2
In a galaxy redshift survey the objects to be targeted for spectra are selected from a photometrically observed sample. The observed magnitudes and colours of galaxies in this pare…
Relativistic distortions in the large-scale clustering of SDSS-III BOSS CMASS galaxies
Shadab Alam, Hongyu Zhu, Rupert A. C. Croft +3
General relativistic effects have long been predicted to subtly influence the observed large-scale structure of the universe. The current generation of galaxy redshift surveys have…
Relativistic asymmetries in the galaxy cross-correlation function
Elena Giusarma, Shadab Alam, Hongyu Zhu +2
We study the asymmetry in the two-point cross-correlation function of two populations of galaxies focusing in particular on the relativistic effects that include the gravitational…
The detection of the imprint of filaments on cosmic microwave background lensing
Siyu He, Shadab Alam, Simone Ferraro +2
Galaxy redshift surveys, such as 2dF, SDSS, 6df, GAMA and VIPERS, have shown that the spatial distribution of matter forms a rich web, known as the cosmic web. The majority of gala…
