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

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 […]

Towards a Muon Collider

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Carlotta Accettura, Dean Adams, Rohit Agarwal, Claudia Ahdida, Chiara Aimè | Summary: A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre […]

Angular spectrum of quantum fluctuations in causal structure

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 […]

Angular correlations on causally-coherent inflationary horizons

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen, | Summary: We develop a model for correlations of cosmic microwave background anisotropy on the largest angular scales, based on standard causal geometrical relationships in slow-roll inflation. Unlike standard models based on quantized field modes, it describes perturbations […]
