Deep-Field Analytical Calibration
Andy Park, Xiangchong Li, Rachel Mandelbaum +1
The next generation of imaging surveys, including the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), Euclid, and the Nancy Grace Roman Space Telescope, will plac…
Accurate Shear Estimation with Fourth-Order Moments
Andy Park, Xiangchong Li, Rachel Mandelbaum
As imaging surveys progress in exploring the large-scale structure of the Universe through the use of weak gravitational lensing, achieving subpercent accuracy in estimating shape…
Matching Cosmic Shear Analysis in Harmonic and Real Space
Andy Park, Sukhdeep Singh, Xiangchong Li +2
Recent cosmic shear analyses have exhibited discrepancies of up to between the inferred cosmological parameters when analyzing summary statistics in real space versus harmonic…
A Differentiable Perturbation-based Weak Lensing Shear Estimator
Xiangchong Li, Rachel Mandelbaum, Mike Jarvis +3
Upcoming imaging surveys will use weak gravitational lensing to study the large-scale structure of the Universe, demanding sub-percent accuracy for precise cosmic shear measurement…
Simulating image coaddition with the Nancy Grace Roman Space Telescope: II. Analysis of the simulated images and implications for weak lensing
Masaya Yamamoto, Katherine Laliotis, Emily Macbeth +16
One challenge for applying current weak lensing analysis tools to the Nancy Grace Roman Space Telescope is that individual images will be undersampled. Our companion paper presente…
Simulating image coaddition with the Nancy Grace Roman Space Telescope: I. Simulation methodology and general results
Christopher M. Hirata, Masaya Yamamoto, Katherine Laliotis +16
The upcoming Nancy Grace Roman Space Telescope will carry out a wide-area survey in the near infrared. A key science objective is the measurement of cosmic structure via weak gravi…
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)…
The LSST-DESC 3x2pt Tomography Optimization Challenge
Joe Zuntz, François Lanusse, Alex I. Malz +25
This paper presents the results of the Rubin Observatory Dark Energy Science Collaboration (DESC) 3x2pt tomography challenge, which served as a first step toward optimizing the tom…
