Resolving the Binary Components of the Outbursting Protostar HBC 494 with ALMA

Kavli Affiliate: David A. Principe | First 5 Authors: Pedro Henrique Nogueira, Alice Zurlo, Sebastián Pérez, Camilo González-Ruilova, Lucas A. Cieza | Summary: Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevated levels of accretion that lasts for decades or […]

X-ray polarimetry of the accreting pulsar GX 301-2

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 […]

Gravitational lensing effect on cosmic birefringence

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 […]

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 […]
