Kavli Affiliate: Herman L. Marshall | First 5 Authors: Valery F. Suleimanov, Sofia V. Forsblom, Sergey S. Tsygankov, Juri Poutanen, Victor Doroshenko | Summary: The phase- and energy-resolved polarization measurements of accreting X-ray pulsars (XRPs) allow us to test different theoretical models of their emission, and they also provide an avenue to determine the emission […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Wuhyun Sohn, James R. Fergusson, E. P. S. Shellard, , | Summary: We present a new independent pipeline for the CMB bispectrum estimation of primordial non-Gaussianity and release a public code for constraining bispectrum shapes of interest based on the Planck 2018 temperature and polarization […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Fumihiro Naokawa, Toshiya Namikawa, , , | Summary: We calculate the effect of gravitational lensing on the parity-odd power spectrum of the cosmic microwave background (CMB) polarization induced by axionlike particles (ALPs). Several recent works have reported a tantalizing hint of cosmic birefringence, a rotation of the […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Abel L. Peirson, Michela Negro, Ioannis Liodakis, Riccardo Middei, Dawoon E. Kim | Summary: We report the first $> 99%$ confidence detection of X-ray polarization in BL Lacertae. During a recent X-ray/$gamma$-ray outburst, a 287 ksec observation (2022 November 27-30) was taken using the Imaging X-ray […]

Kim | Summary: We report the first $> 99%$ confidence detection of X-ray polarization in BL Lacertae. During a recent X-ray/$gamma$-ray outburst, a 287 ksec observation (2022 November 27-30) was taken using the Imaging X-ray Polarimetry […]
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. […]
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 […]
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 […]

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 […]
