Contamination of early-type galaxy alignments to galaxy lensing-CMB lensing cross-correlation
Nora Elisa Chisari, Joanna Dunkley, Lance Miller +1
Galaxy shapes are subject to distortions due to the tidal field of the Universe. The cross-correlation of galaxy lensing with the lensing of the Cosmic Microwave Background (CMB) c…
Intrinsic alignments of galaxies in the Horizon-AGN cosmological hydrodynamical simulation
Nora Elisa Chisari, Sandrine Codis, Clotilde Laigle +7
The intrinsic alignments of galaxies are recognised as a contaminant to weak gravitational lensing measurements. In this work, we study the alignment of galaxy shapes and spins at…
Imprint of inflation on galaxy shape correlations
Fabian Schmidt, Nora Elisa Chisari, Cora Dvorkin
We show that intrinsic (not lensing-induced) correlations between galaxy shapes offer a new probe of primordial non-Gaussianity and inflationary physics which is complementary to g…
