Comparison of Polarized Radiative Transfer Codes used by the EHT Collaboration

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Ben S. Prather, Jason Dexter, Monika Moscibrodzka, Hung-Yi Pu, Thomas Bronzwaer | Summary: Interpretation of resolved polarized images of black holes by the Event Horizon Telescope (EHT) requires predictions of the polarized emission observable by an Earth-based instrument for a particular model of the black hole […]

Absorption of Vector Dark Matter Beyond Kinetic Mixing

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, Tanner Trickle, , , | Summary: Massive vector particles are minimal dark matter candidates that motivate a wide range of laboratory searches, primarily exploiting a postulated kinetic mixing with the photon. However, depending on the high energy field content, the dominant vector dark matter (VDM) […]

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

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 […]

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 […]
