X-Ray Polarization from the Gamma-Ray Binary LS I +61 303

Philip Kaaret, Sudip Chakraborty, Daniel Golonka +5

The gamma-ray emitting binary stellar system LS I +61 303 was observed with the Imaging X-ray Polarimetry Explorer (IXPE) on two successive orbits over orbital phases of 0.74 to 1.…

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,…

First X-ray polarimetric view of a Low-Luminosity Active Galactic Nucleus: the case of NGC 2110

Sudip Chakraborty, Ajay Ratheesh, Daniele Tagliacozzo +20

Low-Luminosity Active Galactic Nuclei (LLAGN) provides a unique view of Comptonization and non-thermal emission from accreting black holes in the low-accretion rate regime. However…

AstroSat timing and spectral analysis of the accretion-powered millisecond X-ray pulsar IGR J17591--2342

Akshay Singh, Andrea Sanna, Sudip Bhattacharyya +5

IGR J17591--2342, a transient accretion-powered millisecond X-ray pulsar, was discovered during its 2018 outburst. Here, we present a timing and spectral analysis of the source usi…
