Pulsed, Polarized X-ray Emission from Neutron Star Surfaces: the Effects of Vacuum Birefringence in the Magnetosphere
Hoa Dinh Thi, Matthew G. Baring, Kun Hu +4
Intense magnetic fields in the atmospheres of neutron stars render non-trivial angular dependence of intensity and polarization of soft X-ray emission originating from their surfac…
NICER Magnetar Burst Catalog
Che-Yen Chu, Chin-Ping Hu, Teruaki Enoto +13
In this paper, we present a comprehensive catalog of short bursts from magnetars based on eight years of NICER observations. A total of 1130 bursts were identified from 14 sources,…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Fast X-ray Transient Detection with AXIS: application to Magnetar Giant Flares
Michela Negro, Zorawar Wadiasingh, George Younes +6
Magnetar giant flares (MGFs) are among the most luminous high-energy transients in the local universe, consisting of a short, intense MeV gamma-ray spike followed by a softer, puls…
Vacuum birefringence and the polarized X-ray emission from a radio magnetar
Rachael E. Stewart, Hoa Dinh Thi, George Younes +13
Magnetars are isolated neutron stars with exceptionally strong surface fields exceeding G. Their bright X-ray emission probes physical regimes in which quantum electrodyn…
A coherent radio burst from an X-ray neutron star in the Carina Nebula
K. M. Rajwade, J. Tian, G. Younes +10
The neutron star zoo comprises several sub-populations that range from energetic magnetars and thermally emitting X-ray neutron stars to radio-emitting pulsars. Despite studies ove…
Rapid Spectral Evolution of SGR 1935+2154 During its 2022 Outburst
Chin-Ping Hu, Zorawar Wadiasingh, Wynn C. G. Ho +9
During the 2022 outburst of SGR 1935+2154, a Fast-Radio-Burst-like event (FRB 20221014A) and X-ray activities occurred between two spin-up glitches, suggesting these glitches may c…
The Galactic population of magnetars : a simulation-based inference study
Mattéo Sautron, Alexander Eli McEwen, George Younes +3
Population synthesis modeling of the observed dynamical and physical properties of a population is a highly effective method for constraining the underlying birth parameters and ev…
Timing and Spectral Evolution of the Magnetar 1E 1841-045 in Outburst
G. Younes, S. K. Lander, M. G. Baring +19
We present the timing and spectral analyses of the NICER, NuSTAR, and IXPE observations of the magnetar 1E 1841-045 covering 82 days following its August 2024 bursting activity as…
