Absolute Flux Calibrations for the Nancy Grace Roman Space Telescope Coronagraph Instrument

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Lindsey Payne, Robert T. Zellem, Marie Ygouf, Bruce Macintosh, | Summary: The Nancy Grace Roman Space Telescope’s (Roman) Coronagraph Instrument is a technology demonstration equipped to achieve flux contrast levels of up to 10$^{-9}$. This precision depends upon the quality of observations and their resultant on-sky corrections […]

Searching for Dark Clumps with Gravitational-Wave Detectors

Kavli Affiliate: Peter W. Graham | First 5 Authors: Sebastian Baum, Michael A. Fedderke, Peter W. Graham, , | Summary: Dark compact objects ("clumps") transiting the Solar System exert accelerations on the test masses (TM) in a gravitational-wave (GW) detector. We reexamine the detectability of these clump transits in a variety of current and future […]

X-ray polarization detection of Cassiopeia A with IXPE

Kavli Affiliate: Nicola Omodei | First 5 Authors: Jacco Vink, Dmitry Prokhorov, Riccardo Ferrazzoli, Patrick Slane, Ping Zhou | Summary: We report on a 5$sigma$ detection of polarized 3-6 keV X-ray emission from the supernova remnant Cassiopeia A with the Imaging X-ray Polarimetry Explorer (IXPE) mission. The overall polarization degree of 1.8 $pm$ 0.3% is […]

When quantum corrections alter the predictions of classical field theory for scalar field dark matter

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Michael Kopp, Tom Abel, , | Summary: We investigate the timescale on which quantum corrections alter the predictions of classical field theory for scalar field dark matter. This is accomplished by including second order terms in the evolution proportional to the covariance of the field […]
