Removing correlated noise stripes from the Nancy Grace Roman Space Telescope survey images
Katherine Laliotis, Christopher M. Hirata, Emily Macbeth +1
Weak gravitational lensing has emerged as a powerful tool for investigating the matter distribution in the Universe and how it has evolved over cosmic time. The Wide Field Instrume…
Simulating Image Coaddition with the Nancy Grace Roman Space Telescope. IV. Hyperparameter Optimization and Experimental Features
Kaili Cao, Christopher M. Hirata, Katherine Laliotis +3
For weak gravitational lensing cosmology with the forthcoming Nancy Grace Roman Space Telescope, image coaddition, or construction of oversampled images from undersampled ones, is…
Deciphering Baryonic Feedback from ACT tSZ Galaxy Clusters
Nihar Dalal, Chun-Hao To, Chris Hirata +4
The next generation of cosmology surveys will probe the matter distribution of the universe to unparalleled precision. To match this level of precision in cosmological parameter es…
OpenUniverse2024: A shared, simulated view of the sky for the next generation of cosmological surveys
OpenUniverse, The LSST Dark Energy Science Collaboration, The Roman HLIS Project Infrastructure Team +58
The OpenUniverse2024 simulation suite is a cross-collaboration effort to produce matched simulated imaging for multiple surveys as they would observe a common simulated sky. Both t…
