Challenges facing young astrophysicists
N. L. Zakamska, A. E. Schulz, K. Heng +9
In order to attract and retain excellent researchers and diverse individuals in astrophysics, we recommend action be taken in several key areas impacting young scientists: (1) Main…
Precision photometric redshift calibration for galaxy-galaxy weak lensing
R. Mandelbaum, U. Seljak, C. M. Hirata +26
Accurate photometric redshifts are among the key requirements for precision weak lensing measurements. Both the large size of the Sloan Digital Sky Survey (SDSS) and the existence…
Dark Matter Structures in the Universe: Prospects for Optical Astronomy in the Next Decade
P. J. Marshall, M. Auger, J. G. Bartlett +13
The Cold Dark Matter theory of gravitationally-driven hierarchical structure formation has earned its status as a paradigm by explaining the distribution of matter over large spans…
Testing the Impact of Satellite Anisotropy on Large and Small Scale Intrinsic Alignments using Hydrodynamical Simulations
S. Samuroff, R. Mandelbaum, T. Di Matteo
Galaxy intrinsic alignments (IAs) have long been recognised as a significant contaminant to weak lensing-based cosmological inference. In this paper we seek to quantify the impact…
Photometric redshift requirements for lens galaxies in galaxy-galaxy lensing analyses
R. Nakajima, R. Mandelbaum, U. Seljak +3
Weak gravitational lensing is a valuable probe of galaxy formation and cosmology. Here we quantify the effects of using photometric redshifts (photo-z) in galaxy-galaxy lensing, fo…
A Joint Roman Space Telescope and Rubin Observatory Synthetic Wide-Field Imaging Survey
M. A. Troxel, C. Lin, A. Park +22
We present and validate 20 deg of overlapping synthetic imaging surveys representing the full depth of the Nancy Grace Roman Space Telescope High-Latitude Imaging Survey (HLIS)…
