X-ray Polarization of the Black Hole X-ray Binary 4U 1630-47 Challenges Standard Thin Accretion Disk Scenario

Kavli Affiliate: Herman Marshall | First 5 Authors: Ajay Ratheesh, Michal Dovčiak, Henric Krawczynski, Jakub Podgorný, Lorenzo Marra | Summary: Large energy-dependent X-ray polarization degree is detected by the Imaging X-ray Polarimetry Explorer ({IXPE}) in the high-soft emission state of the black hole X-ray binary 4U 1630–47. The highly significant detection (at $approx50sigma$ confidence level) […]

Proposed host galaxies of repeating fast radio burst sources detected by CHIME/FRB

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adaeze L. Ibik, Maria R. Drout, B. M. Gaensler, Paul Scholz, Daniele Michilli | Summary: We present a search for host galaxy associations for the third set of repeating fast radio burst (FRB) sources discovered by the CHIME/FRB Collaboration. Using the $sim$ 1 arcmin CHIME/FRB baseband […]

Asymptotic gravitational-wave fluxes from a spinning test body on generic orbits around a Kerr black hole

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Viktor Skoupý, Georgios Lukes-Gerakopoulos, Lisa V. Drummond, Scott A. Hughes, | Summary: This work provides gravitational wave energy and angular momentum asymptotic fluxes from a spinning body moving on generic orbits in a Kerr spacetime up to linear in spin approximation. To achieve this, we have […]

Three Saturn-mass planets transiting F-type stars revealed with TESS and HARPS

Kavli Affiliate: Gabor Furesz | First 5 Authors: Angelica Psaridi, François Bouchy, Monika Lendl, Babatunde Akinsanmi, Keivan G. Stassun | Summary: While the sample of confirmed exoplanets continues to increase, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investigate the planet properties and formation pathways over a […]
