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…

X-ray/UVOIR Frequency-resolved Time Lag Analysis of Mrk 335 Reveals Accretion Disk Reprocessing

Collin Lewin, Erin Kara, Edward M. Cackett +4

UV and optical continuum reverberation mapping is powerful for probing the accretion disk and inner broad-line region. However, recent reverberation mapping campaigns in the X-ray,…

Discovery of strongly variable X-ray polarization in the neutron star low-mass X-ray binary transient XTE J1701462

Massimo Cocchi, Andrea Gnarini, Sergio Fabiani +105

After about 16 years since its first outburst, the transient neutron star low-mass X-ray binary XTE J1701462 turned on again in September 2022, allowing for the first study of i…

First detection of X-ray polarization from the accreting neutron star 4U 1820-303

Alessandro Di Marco, Fabio La Monaca, Juri Poutanen +116

This paper reports the first detection of polarization in the X-rays for atoll-source 4U 1820-303, obtained with the Imaging X-ray Polarimetry Explorer (IXPE) at 99.999% confidence…

Complex variations of X-ray polarization in the X-ray pulsar LS V +44 17/RX J0440.9+4431

Victor Doroshenko, Juri Poutanen, Jeremy Heyl +109

We report on Imaging X-ray polarimetry explorer (IXPE) observations of the Be-transient X-ray pulsar LS V +44 17/RX J0440.9+4431 made at two luminosity levels during the giant outb…

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…
