Autor: Nicholas Van Alfen, Duncan Campbell, Jonathan Blazek, C. Danielle Leonard, Francois Lanusse, Andrew Hearin, Rachel Mandelbaum, The LSST Dark Energy Science Collaboration

Publikováno v: The Open Journal of Astrophysics, Vol 7 (2024)

We extend current models of the halo occupation distribution (HOD) to include a flexible, empirical framework for the forward modeling of the intrinsic alignment (IA) of galaxies. A primary goal of this work is to produce mock galaxy catalogs for the
