X-ray polarization of reflected thermal emission

J. Podgorný, M. Dovčiak, R. Goosmann +5

We compute rest-frame reflection spectra and the corresponding energy-dependent linear polarization degree and angle for (un)polarized single-temperature blackbody spectra impingin…

Polarization properties of thermal accretion disk emission. I. Direct radiation

L. Marra, J. Podgorný, R. Taverna +4

The X-ray polarimetric observing window re-opening is shedding new light on our current understanding of compact accreting sources. This is true, in particular, for stellar-mass bl…

Recovery of the X-ray polarisation of Swift J1727.81613 after the soft-to-hard spectral transition

J. Podgorný, J. Svoboda, M. Dovčiak +34

We report on the detection of X-ray polarisation in the black-hole X-ray binary Swift J1727.81613 during its dim hard spectral state by the Imaging X-ray Polarimetry Explorer (I…

Shape and ionization of equatorial matter near compact objects from X-ray polarization reflection signatures

J. Podgorný

Motivated by the success of the IXPE mission, we elucidate what can be inferred about 3D matter structures forming about the equatorial plane of accreting compact objects from 0.1-…

Exploring MAXI J1744-294: IXPE insights into a Newly Discovered X-ray Transient

Lorenzo Marra, Romana Mikušincová, Federico M. Vincentelli +33

We present the first IXPE spectro-polarimetric observation of the black hole candidate MAXI J1744294, a transient X-ray source discovered during a bright 2025 outburst in the Ga…

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…
