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…
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…
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…
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…
