Jingjing Shi is a IPMU fellow at Kavli IPMU in Japan. She investigates the interplay between large scale structure, dark matter halos, and galaxies. She got her PhD in 2017 from SISSA in Italy. Prior to joining IPMU, she was a Boya fellow at KIAA in Peking University.
Talk Title and Abstract:
Galaxy Intrinsic Alignment
Abstract: The intrinsic shape of galaxies align with each other. Such galaxy intrinsic alignment is a main contamination for cosmic shear measurement. However it also contains useful cosmological information. We have studied the galaxy shape/spin alignments in cosmological hydrodynamical simulations using 3d intrinsic alignment power spectrum for galaxies with varying mass, redshift, morphology, and environment. We also developed a new shape estimator that can be applied to ongoing/future cosmology survey, for extracting the cosmological information encoded in intrinsic alignment.
