Discovery of a strong rotation of the X-ray polarization angle in the galactic burster GX 13+1

Kavli Affiliate: Nicola Omodei | First 5 Authors: Anna Bobrikova, Sofia V. Forsblom, Alessandro Di Marco, Fabio La Monaca, Juri Poutanen | Summary: Weakly magnetized neutron stars in X-ray binaries show complex phenomenology with several spectral components that can be associated with the accretion disk, boundary and/or spreading layer, a corona, and a wind. Spectroscopic […]

How well does surface magnetism represent deep Sun-like star dynamo action?

Kavli Affiliate: Robert Cameron | First 5 Authors: Adam J. Finley, Sacha A. Brun, Antoine Strugarek, Robert Cameron, | Summary: For Sun-like stars, the generation of toroidal magnetic field from poloidal magnetic field is an essential piece of the dynamo mechanism powering their magnetism. Previous authors have estimated the net toroidal flux generated in each […]

Forecasts for Galaxy Formation and Dark Matter Constraints from Dwarf Galaxy Surveys

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Vera Gluscevic, Trey Driskell, Risa H. Wechsler, Leonidas A. Moustakas | Summary: The abundance of faint dwarf galaxies is determined by the underlying population of low-mass dark matter (DM) halos and the efficiency of galaxy formation in these systems. Here, we quantify potential […]

Polarization Leakage and the IXPE PSF

Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Roger W. Romani, , , | Summary: By measuring photoelectron tracks, the gas pixel detectors of the Imaging X-ray Polarimetry Explorer satellite provide estimates of the photon detection location and its electric vector position angle (EVPA). However, imperfections in reconstructing event positions blur […]
