Supermassive Black Hole Winds in X-rays -- SUBWAYS. III. A population study on ultra-fast outflows

V. E. Gianolli, S. Bianchi, P-O Petrucci +44

The detection of blue-shifted absorption lines likely associated with ionized Iron K-shell transitions in the X-ray spectra of many Active Galactic Nuclei (AGN) suggests the presen…

X-ray Polarization of the BL Lac Type Blazar 1ES 0229+200

Steven R. Ehlert, Ioannis Liodakis, Riccardo Middei +110

We present polarization measurements in the band from blazar 1ES 0229+200, the first extreme high synchrotron peaked source to be observed by the Imag…

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…

A remarkably stable accretion disc in the Seyfert galaxy MCG-5-23-16

Roberto Serafinelli, Andrea Marinucci, Alessandra De Rosa +12

MCG-5-23-16 is a Seyfert 1.9 galaxy at redshift z=0.00849. We analyse here the X-ray spectra obtained with XMM-Newton and NuSTAR data, which are the first contemporaneous observati…
