A new NASA Pioneer: the Globe Orbiting Soft X-ray Polarimeter (GOSoX)
Herman L Marshall, Sarah N T Heine, Alan Garner +16
The Globe Orbiting Soft X-ray Polarimeter (GOSoX) is a spectropolarimeter for the soft X-ray band. GOSoX is based on the Rocket Experiment Demonstration of a Soft X-ray Polarimeter…
The long quest for vacuum birefringence in magnetars: 1E 1547.0-5408 and the elusive smoking gun
Roberto Taverna, Roberto Turolla, Lorenzo Marra +7
Magnetars are now known to be among the most strongly polarized celestial sources in X-rays. Here we report on the observation of the magnetar 1E 1547.0-5408 per…
Physics of Strong Magnetism with eXTP
Mingyu Ge, Long Ji, Roberto Taverna +47
In this paper we present the science potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission, in its new configuration, for studies of strongly magnetized compact obj…
Exploring the Future of Soft X-ray Polarimetry: the Capabilities of the REDSoX Instrument for XDINS and Magnetar Studies
Ruth M. E. Kelly, Herman L. Marshall, Silvia Zane +5
X-ray polarimetry offers a unique window into neutron star physics and can provide answers to questions that cannot otherwise be probed. The up-and-coming REDSoX sounding rocket mi…
Exploring polarization and geometry in the X-ray pulsar 4U 1538-52
Vladislav Loktev, Sofia V. Forsblom, Sergey S. Tsygankov +12
The Imaging X-ray Polarimetry Explorer (IXPE) observations of accreting X-ray pulsars (XRPs) continue to provide novel insights into the physics and geometry of these sources. We p…
IXPE detection of highly polarized X-rays from the magnetar 1E 1841-045
Michela Rigoselli, Roberto Taverna, Sandro Mereghetti +12
The Imaging X-ray Polarimetry Explorer (IXPE) observed for the first time highly polarized X-ray emission from the magnetar 1E 1841-045, targeted after a burst-active phase in Augu…
