Machine Learning for Quantum-Enhanced Gravitational-Wave Observatories

Kavli Affiliate: Lisa Barsotti | First 5 Authors: Chris Whittle, Ge Yang, Matthew Evans, Lisa Barsotti, | Summary: Machine learning has become an effective tool for processing the extensive data sets produced by large physics experiments. Gravitational-wave detectors are now listening to the universe with quantum-enhanced sensitivity, accomplished with the injection of squeezed vacuum states. […]

Discovery of X-ray polarization angle rotation in active galaxy Mrk 421

Kavli Affiliate: Grzegorz Madejski | First 5 Authors: Laura Di Gesu, Herman L. Marshall, Steven R. Ehlert, Dawoon E. Kim, Immacolata Donnarumma | Summary: The magnetic field conditions in astrophysical relativistic jets can be probed by multiwavelength polarimetry, which has been recently extended to X-rays. For example, one can track how the magnetic field changes […]

Small Region, Big Impact: Highly Anisotropic Lyman-continuum Escape from a Compact Starburst Region with Extreme Physical Properties

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keunho J. Kim, Matthew B. Bayliss, Jane R. Rigby, Michael D. Gladders, John Chisholm | Summary: Extreme, young stellar populations are considered the primary contributor to cosmic reionization. However, how Lyman-continuum (LyC) escapes these galaxies remains highly elusive because LyC escape can vary on sub-galactic scales […]

Clustering of Primordial Black Holes from QCD Axion Bubbles

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Naoya Kitajima, Kai Murai, Shunsuke Neda | Summary: We study the clustering of primordial black holes (PBHs) and axion miniclusters produced in the model proposed to explain the LIGO/Virgo events or the seeds of the supermassive black holes (SMBHs) in arXiv:2006.13137. It is […]

Unveiling the small-scale jets in the rapidly growing supermassive black hole IZw1

Kavli Affiliate: Ran Wang | First 5 Authors: Xiaolong Yang, Su Yao, Luigi C. Gallo, Jun Yang, Luis C. Ho | Summary: Accretion of black holes at near-Eddington or super-Eddington rates is the most powerful episode that drives black hole growth, and it may work in several types of objects. However, the physics of accretion […]
