Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE
V. E. Gianolli, D. E. Kim, S. Bianchi +106
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
The IXPE view of GRB 221009A
Michela Negro, Niccoló Di Lalla, Nicola Omodei +108
We present the IXPE observation of GRB 221009A which includes upper limits on the linear polarization degree of both prompt and afterglow emission in the soft X-ray energy band. GR…
Handling Background in IXPE polarimetric data
Alessandro Di Marco, Paolo Soffitta, Enrico Costa +18
IXPE (Imaging X-ray Polarimetry Explorer) is a Small Explorer mission by NASA and ASI, launched on December 9 2021, dedicated to investigating X-ray polarimetry allowing ang…
A strong X-ray polarization signal from the magnetar 1RXS J170849.0-400910
Silvia Zane, Roberto Taverna, Denis Gonzalez Caniulef +99
Magnetars are the most strongly magnetized neutron stars, and one of the most promising targets for X-ray polarimetric measurements. We present here the first Imaging X-ray Polarim…
Compton Polarimetry
Ettore Del Monte, Sergio Fabiani, Mark Pearce
Photons preferentially Compton scatter perpendicular to the plane of polarisation. This property can be exploited to design instruments to measure the linear polarisation of hard X…
X-ray polarimetry reveals the magnetic field topology on sub-parsec scales in Tycho's supernova remnant
Riccardo Ferrazzoli, Patrick Slane, Dmitry Prokhorov +97
Supernova remnants are commonly considered to produce most of the Galactic cosmic rays via diffusive shock acceleration. However, many questions about the physical conditions at sh…
