Constraining cosmology with shear peak statistics: tomographic analysis
Nicolas Martinet, James G. Bartlett, Alina Kiessling +1
The abundance of peaks in weak gravitational lensing maps is a potentially powerful cosmological tool, complementary to measurements of the shear power spectrum. We study peaks det…
Galaxy shapes and alignments in the MassiveBlack-II hydrodynamic and dark matter-only simulations
Ananth Tenneti, Rachel Mandelbaum, Tiziana Di Matteo +2
We compare the shapes and intrinsic alignments of galaxies in the MassiveBlack-II cosmological hydrodynamic simulation (MBII) to those in a dark matter-only (DMO) simulation perfor…
Hierarchical Cosmic Shear Power Spectrum Inference
Justin Alsing, Alan Heavens, Andrew H. Jaffe +3
We develop a Bayesian hierarchical modelling approach for cosmic shear power spectrum inference, jointly sampling from the posterior distribution of the cosmic shear field and its…
