The Polarized Cosmic Hand: IXPE Observations of PSR B1509-58/MSH 15-52
Roger W. Romani, Josephine Wong, Niccolo Di Lalla +99
We describe IXPE polarization observations of the Pulsar Wind Nebula (PWN) MSH15-52, the `Cosmic Hand'. We find X-ray polarization across the PWN, with B field vectors generally al…
Discovery of X-ray Polarization from the Black Hole Transient Swift J1727.8-1613
Alexandra Veledina, Fabio Muleri, Michal Dovciak +113
We report the first detection of the X-ray polarization of the bright transient Swift J1727.8-1613 with the Imaging X-ray Polarimetry Explorer. The observation was performed at the…
First X-ray polarization measurement confirms the low black-hole spin in LMC X-3
Jiří Svoboda, Michal Dovčiak, James F. Steiner +109
X-ray polarization is a powerful tool to investigate the geometry of accreting material around black holes, allowing independent measurements of the black hole spin and orientation…
Magnetic structures and turbulence in SN 1006 revealed with imaging X-ray polarimetry
Ping Zhou, Dmitry Prokhorov, Riccardo Ferrazzoli +99
Young supernova remnants (SNRs) strongly modify surrounding magnetic fields, which in turn play an essential role in accelerating cosmic rays (CRs). X-ray polarization measurements…
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…
IXPE and multi-wavelength observations of blazar PG 1553+113 reveal an orphan optical polarization swing
Riccardo Middei, Matteo Perri, Simonetta Puccetti +119
The lower energy peak of the spectral energy distribution of blazars has commonly been ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consen…
