Simulating image coaddition with the Nancy Grace Roman Space Telescope: II. Analysis of the simulated images and implications for weak lensing

Posted by Chicago

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Masaya Yamamoto, Katherine Laliotis, Emily Macbeth, Tianqing Zhang, Christopher M. Hirata | Summary: 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 presented an initial application of Imcom – an […]

Simulating image coaddition with the Nancy Grace Roman Space Telescope: I. Simulation methodology and general results

Posted by Chicago

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Christopher M. Hirata, Masaya Yamamoto, Katherine Laliotis, Emily Macbeth, M. A. Troxel | Summary: 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 gravitational lensing. Roman data […]

Constraints on axion-like polarization oscillations in the cosmic microwave background with POLARBEAR

Posted by klaurent Tokyo

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: The POLARBEAR Collaboration, Shunsuke Adachi, Tylor Adkins, Kam Arnold, Carlo Baccigalupi | Summary: Very light pseudoscalar fields, often referred to as axions, are compelling dark matter candidates and can potentially be detected through their coupling to the electromagnetic field. Recently a novel detection technique using the cosmic […]

Angular spectrum of quantum fluctuations in causal structure

Posted by Chicago

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Nathaniel Selub, , | Summary: Scaling arguments are used to constrain the angular spectrum of distortions on boundaries of macroscopic causal diamonds, produced by Planck-scale vacuum fluctuations of causally-coherent quantum gravity. The small-angle spectrum of displacement is derived from a form of scale […]
