Vacuum birefringence and the polarized X-ray emission from a radio magnetar
Rachael E. Stewart, Hoa Dinh Thi, George Younes +13
The paper presents phase- and energy-resolved X‑ray polarization measurements of the radio magnetar 1E 1547.0‑5408, finding high polarization degrees that support vacuum birefringe…
Transient narrowband radio bursts from the magnetar 1E 1547.0-5408
Marcus E. Lower, Paul Scholz, Fernando Camilo +5
Radio-loud magnetars are well known for exhibiting radiative behaviors that are seldom seen among the wider pulsar population. Yet one form of emission that remains elusive among p…
Pulsed Infrared Emission from Magnetar 4U 0142+61 Detected by JWST
Jeremy Hare, George G. Pavlov, Bettina Posselt +3
We report on a JWST observation of the magnetar 4U 0142+61 on 2024 August 18 with the Near-Infrared Camera (NIRCam). NIRCam observed the magnetar for 33~min in timing mode, providi…
Detailed Timing, Spectral, and Polarimetric Analysis of Magnetar 1RXS J170849.0-400910
Rachael Stewart, George Younes, Alice Harding +5
We present a broadband timing, spectral, and polarimetric study of the magnetar 1RXS~J170849.0-400910 using XMM-Newton, NuSTAR, and IXPE. The pulse morphology evolves strongly acro…
Magnetar Fireballs and Short Bursts: Curved Spacetime Lensing, QED Effects, Spectra, Polarization, and Impulse Responses
Zorawar Wadiasingh, Hoa Dinh Thi, Constantinos Kalapotharakos +13
Magnetar short bursts (SBs) are hard X-ray transients of durations s peaking at keV, and are prime targets for new high-energy missions and polarimeters. The…
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,…
