Magnetar counterparts, kinematics and birth sites with HST and JWST
A. A. Chrimes, J. D. Lyman, A. J. Levan +7
Magnetars are highly magnetised, isolated neutron stars with uncertain formation channels. They comprise a potentially significant fraction of the young neutron star population in…
Resolving the 2024 Outburst of Magnetar 1E 1841-045 from its host Supernova Remnant with EP-FXT
Yu-Cong Fu, Lin Lin, Yu-Jia Zheng +11
The magnetar 1E 1841-045 exhibited a new active episode starting on August 20, 2024, marked by X-ray bursts and enhanced persistent emission. Using data from the Einstein Probe (EP…
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,…
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…
Searching for quasi-periodicities in short transients: the curious case of GRB 230307A
Daniela Huppenkothen, Matthew G. Baring, Mete Uzuner +5
Gamma-ray bursts (GRBs) are the most powerful explosions in the Universe; their energy release reache s us from the end of the re-ionization era, making them invaluable cosmologica…
The infrared counterpart and proper motion of magnetar SGR0501+4516
A. A. Chrimes, A. J. Levan, J. D. Lyman +19
Soft gamma repeaters (SGRs) are highly magnetised neutron stars (magnetars) notable for their gamma-ray and X-ray outbursts. In this paper, we use near-infrared (NIR) imaging of SG…
