X-ray polarization of the magnetar 1E 1841-045
Rachael Stewart, George A. Younes, Alice K. Harding +15
We report on IXPE and NuSTAR observations beginning forty days after the 2024 outburst onset of magnetar 1E 1841-045, marking the first IXPE observation of a magnetar in an enhance…
Pulsed and Polarized X-ray Emission from Neutron Star Surfaces
Matthew G. Baring, Hoa Dinh Thi, George A. Younes +1
The intense magnetic fields of neutron stars naturally lead to strong anisotropy and polarization of radiation emanating from their surfaces, both being sensitive to the hot spot p…
GRB 221009A: the B.O.A.T Burst that Shines in Gamma Rays
M. Axelsson, M. Ajello, M. Arimoto +151
We present a complete analysis of Fermi Large Area Telescope (LAT) data of GRB 221009A, the brightest Gamma-Ray Burst (GRB) ever detected. The burst emission above 30 MeV detected…
Extragalactic Magnetar Giant Flare GRB 231115A: Insights from Fermi/GBM Observations
Aaron C. Trigg, Rachael Stewart, Alex Van Kooten +22
We present the detection and analysis of GRB 231115A, a candidate extragalactic magnetar giant flare (MGF) observed by Fermi/GBM and localized by INTEGRAL to the starburst galaxy M…
The role of magnetar transient activity in time-domain and multimessenger astronomy
Michela Negro, George Younes, Zorawar Wadiasingh +3
Time-domain and multimessenger astronomy (TDAMM) involves the study of transient and time-variable phenomena across various wavelengths and messengers. The Astro2020 Decadal Survey…
Concise Spectrotemporal Studies of Magnetar SGR J1935+2154 Bursts
Ozge Keskin, Ersin Gogus, Yuki Kaneko +6
SGR J1935+2154 has truly been the most prolific magnetar over the last decade: It has been entering into burst active episodes once every 1-2 years since its discovery in 2014, it…
