The detection of polarized x-ray emission from the magnetar 1E 2259+586
Jeremy Heyl, Roberto Taverna, Roberto Turolla +98
We report on IXPE, NICER and XMM-Newton observations of the magnetar 1E 2259+586. We find that the source is significantly polarized at about or above 20% for all phases except for…
X-ray and Radio Monitoring of the Neutron Star Low Mass X-ray Binary 1A 1744-361: Quasi Periodic Oscillations, Transient Ejections, and a Disk Atmosphere
Mason Ng, Andrew K. Hughes, Jeroen Homan +19
We report on X-ray (NICER/NuSTAR/MAXI/Swift) and radio (MeerKAT) timing and spectroscopic analysis from a three-month monitoring campaign in 2022 of a high-intensity outburst of th…
IXPE and XMM-Newton observations of the Soft Gamma Repeater SGR 1806-20
Roberto Turolla, Roberto Taverna, Gian Luca Israel +96
Recent observations with the Imaging X-ray Polarimetry Explorer (IXPE) of two anomalous X-ray pulsars provided evidence that X-ray emission from magnetar sources is strongly polari…
Thermonuclear Type-I X-ray Bursts and Burst Oscillations from the Eclipsing AMXP Swift J1749.4-2807
A. C. Albayati, P. Bult, D. Altamirano +10
Swift J1749.4-2807 is the only known eclipsing accreting millisecond X-ray pulsar. In this paper, we report on 7 thermonuclear (Type-I) X-ray bursts observed by NICER during its 20…
Probing spectral and timing properties of the X-ray pulsar RX J0440.9+4431 in the giant outburst of 2022-2023
Manoj Mandal, Rahul Sharma, Sabyasachi Pal +10
The X-ray pulsar RX J0440.9+4431 went through a giant outburst in 2022 and reached a record-high flux of 2.3 Crab, as observed by Swift/BAT. We study the evolution of different spe…
A polarimetrically oriented X-ray stare at the accreting pulsar EXO 2030+375
Christian Malacaria, Jeremy Heyl, Victor Doroshenko +104
Accreting X-ray pulsars (XRPs) are presumably ideal targets for polarization measurements, as their high magnetic field strength is expected to polarize the emission up to a polari…
