Inferring Black Hole Properties from Astronomical Multivariate Time Series with Bayesian Attentive Neural Processes

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Ji Won Park, Ashley Villar, Yin Li, Yan-Fei Jiang, Shirley Ho | Summary: Among the most extreme objects in the Universe, active galactic nuclei (AGN) are luminous centers of galaxies where a black hole feeds on surrounding matter. The variability patterns of the light emitted by […]

Earth as a transducer for dark-photon dark-matter detection

Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia, | Summary: We propose the use of the Earth as a transducer for ultralight dark-matter detection. In particular we point out a novel signal of kinetically mixed dark-photon dark matter: a monochromatic oscillating magnetic […]

MP3 White Paper 2021 — Research Opportunities Enabled by Co-locating Multi-Petawatt Lasers with Dense Ultra-Relativistic Electron Beams

Kavli Affiliate: Roger Blandford | First 5 Authors: Sebastian Meuren, David A. Reis, Roger Blandford, Phil H. Bucksbaum, Nathaniel J. Fisch | Summary: Novel emergent phenomena are expected to occur under conditions exceeding the QED critical electric field, where the vacuum becomes unstable to electron-positron pair production. The required intensity to reach this regime, $sim10^{29},mathrm{Wcm^{-2}}$, […]
