Self-calibration method for II and GI types of intrinsic alignments of galaxies
Ji Yao, Mustapha Ishak, M. A. Troxel
We introduce a self-calibration method that can be applied to the intrinsic ellipticity--intrinsic ellipticity (II) and gravitational shear -- intrinsic ellipticity (GI) types of i…
Effects of Self-Calibration of Intrinsic Alignment on Cosmological Parameter Constraints from Future Cosmic Shear Surveys
Ji Yao, Mustapha Ishak, Weikang Lin +1
Intrinsic alignments (IA) of galaxies have been recognized as one of the most serious contaminants to weak lensing. These systematics need to be isolated and mitigated in order for…
Effect of inhomogeneities on high precision measurements of cosmological distances
Austin Peel, M. A. Troxel, Mustapha Ishak
We study effects of inhomogeneities on distance measures in an exact relativistic Swiss-cheese model of the universe, focusing on the distance modulus. The model has LCDM backgroun…
The Intrinsic Alignment of Galaxies and its Impact on Weak Gravitational Lensing in an Era of Precision Cosmology
M. A. Troxel, Mustapha Ishak
The wealth of incoming and future cosmological observations will allow us to map out the structure and evolution of the observable universe to an unprecedented level of precision.…
Cross-correlation between cosmic microwave background lensing and galaxy intrinsic alignment as a contaminant to gravitational lensing cross-correlated probes of the universe
M. A. Troxel, Mustapha Ishak
We introduce here a cross-correlation term between CMB lensing and galaxy intrinsic alignment, noted hereby as . This effect acts as a contaminant to the cross-correlation betw…
The effects of structure anisotropy on lensing observables in an exact general relativistic setting for precision cosmology
M. A. Troxel, Mustapha Ishak, Austin Peel
The study of relativistic, higher order and nonlinear effects has become necessary in recent years in the pursuit of precision cosmology. We develop and apply here a framework to s…
