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…
