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…

NuSTAR Observations of Abell 665 and 2146: Constraints on Non-Thermal Emission

Randall Rojas Bolivar, Daniel Wik, Ayşegül Tümer +11

Observations from past missions such as RXTE and Beppo-SAX suggested the presence of inverse Compton (IC) scattering at hard X-ray energies within the intracluster medium of some m…

Discovery of X-ray polarization angle rotation in active galaxy Mrk 421

Laura Di Gesu, Herman L. Marshall, Steven R. Ehlert +140

The magnetic field conditions in astrophysical relativistic jets can be probed by multiwavelength polarimetry, which has been recently extended to X-rays. For example, one can trac…

The geometry of the hot corona in MCG-05-23-16 constrained by X-ray polarimetry

D. Tagliacozzo, A. Marinucci, F. Ursini +105

We report on the second observation of the radio-quiet active galactic nucleus (AGN) MCG-05-23-16 performed with the Imaging X-ray Polarimetry Explorer (IXPE). The observation star…

X-ray Polarization of BL Lacertae in Outburst

Abel L. Peirson, Michela Negro, Ioannis Liodakis +128

We report the first confidence detection of X-ray polarization in BL Lacertae. During a recent X-ray/-ray outburst, a 287 ksec observation (2022 November 27-30) was tak…

The X-ray polarisation of the Seyfert 1 galaxy IC 4329A

A. Ingram, M. Ewing, A. Marinucci +105

We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy IC 4329A. The Imaging X-ray Polarimetry Explorer (IXPE) observed the source for ~500 ks, supported by…
