Robust Photometry for Roman High-Latitude Imaging Survey Cosmology Using Roman and Rubin Imaging
Chun-Hao To, Tae-Hyeon Shin, Chihway Chang +18
Accurate and precise photometry is essential for Roman cosmology because it affects photometric-redshift performance, galaxy and cluster selection, tomographic binning, and redshif…
Modeling the impact of filter-substrate refraction in the Roman point spread function
Federico Berlfein, Rachel Mandelbaum, Tianqing Zhang +4
For broadband imaging surveys, filter-substrate refraction causes light at different wavelengths to follow slightly different paths through the filter substrate before reaching the…
Charge diffusion and modulation transfer function in a Nancy Grace Roman Space Telescope detector
Emily Macbeth, Katherine Laliotis, Christopher M. Hirata +1
The Nancy Grace Roman Space Telescope (Roman) is an observatory motivated by the search to understand dark energy, exoplanets, and general astrophysics. Roman will bring unpreceden…
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…
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…
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…
