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)…
Recommended Target Fields for Commissioning the Vera C. Rubin Observatory
A. Amon, K. Bechtol, A. J. Connolly +13
The commissioning team for the Vera C. Rubin observatory is planning a set of engineering and science verification observations with the Legacy Survey of Space and Time (LSST) comm…
The LSST DESC DC2 Simulated Sky Survey
LSST Dark Energy Science Collaboration, Bela Abolfathi, David Alonso +77
We describe the simulated sky survey underlying the second data challenge (DC2) carried out in preparation for analysis of the Vera C. Rubin Observatory Legacy Survey of Space and…
The LSST DESC Data Challenge 1: Generation and Analysis of Synthetic Images for Next Generation Surveys
F. Javier Sánchez, Chris W. Walter, Humna Awan +23
Data Challenge 1 (DC1) is the first synthetic dataset produced by the Rubin Observatory Legacy Survey of Space and Time (LSST) Dark Energy Science Collaboration (DESC). DC1 is desi…
High fidelity point-spread function retrieval in the presence of electrostatic, hysteretic pixel response
Andrew Rasmussen, Augustin Guyonnet, Craig Lage +11
We employ electrostatic conversion drift calculations to match CCD pixel signal covariances observed in flat field exposures acquired using candidate sensor devices for the LSST Ca…
The Brighter-Fatter and other Sensor Effects in CCD Simulations for Precision Astronomy
C. W. Walter
Upcoming and current large astronomical survey experiments often seek to constrain cosmological parameters via measurements of subtle effects such as weak lensing, which can only b…
