OpenCosmo: Community Portal and Analysis Framework for Flagship Cosmological Simulations
Patrick R. Wells, Michael Buelhmann, Michael Buehlmann +12
Cosmology is a precision observational science, and large simulations are necessary components of many analyses. These simulations are computationally expensive and produce massive…
SPHEREx: NASA's Near-Infrared Spectrophotmetric All-Sky Survey
Brendan P. Crill, Michael Werner, Rachel Akeson +51
SPHEREx, the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and ices Explorer, is a NASA MIDEX mission planned for launch in 2024. SPHEREx will carry ou…
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)…
Snowmass2021 Computational Frontier White Paper: Cosmological Simulations and Modeling
Marcelo A. Alvarez, Arka Banerjee, Simon Birrer +9
Powerful new observational facilities will come online over the next decade, enabling a number of discovery opportunities in the "Cosmic Frontier", which targets understanding of t…
