Cross-Correlation between Cosmic Microwave Background Lensing and Galaxy Intrinsic Alignment as a Contaminant to Gravitational Lensing Cross-Correlated Probes of the Universe
(American Physical Society, 2014-03-25)
We introduce here a cross-correlation term between CMB lensing and galaxy intrinsic alignment, noted here as φl. This effect acts as a contaminant to the cross correlation between CMB lensing and galaxy lensing. The latter ...
First Detection of the GI-Type of Intrinsic Alignments of Galaxies Using the Selfcalibration Method in a Photometric Galaxy Survey
(Institute of Physics, 2020-08-05)
Weak gravitational lensing is one of the most promising cosmological probes to constrain dark matter, dark energy, and the nature of gravity at cosmic scales. Intrinsic alignments (IAs) of galaxies have been recognized as ...
