Where within the 3C 84 jet are -rays produced?

Georgios F. Paraschos, Ioannis Liodakis, Svetlana Jorstad +49

The location of -ray creation and emission within extra-galactic jets is a matter of active debate. One particularly well-suited source to pinpoint the location is the nearby,…

Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry

Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97

RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…

Polarization of reflected X-ray emission from the Sgr A molecular complex: multiple flares, multiple sources?

Ildar Khabibullin, Eugene Churazov, Riccardo Ferrazzoli +100

The extended X-ray emission observed in the direction of several molecular clouds in the central molecular zone of our Galaxy exhibits spectral and temporal properties consistent w…

Super-Eddington Accretion Geometry: a Remarkable Stability of the Hidden Ultraluminous X-Ray Source Cygnus X-3

Romana Mikušincová, Alexandra Veledina, Fabio Muleri +112

We report on the average and orbital phase-resolved polarization of Cyg X-3 in the hard state during the 2023 Imaging X-ray Polarimetry Explorer (IXPE) observational campaign. We f…

Detection of Compton scattering in the jet of 3C 84

Ioannis Liodakis, Sudip Chakraborty, Frédéric Marin +77

3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low frequency radi…

X-ray Polarization Detection of the Pulsar Wind Nebula in G21.5-0.9 with IXPE

Niccolò Di Lalla, Nicola Omodei, Niccolò Bucciantini +98

We present the X-ray polarization observation of G21.5-0.9, a young Galactic supernova remnant (SNR), conducted with the Imaging X-ray Polarimetry Explorer (IXPE) in October 2023,…
