Inelastic scattering effects on polarization predictions for cold and warm atmospheres in the X-rays
J. Podgorný, L. Marra, M. Dovčiak +8
X-ray polarization models of accreting compact objects often assume the so-called Chandrasekhar-Sobolev polarization prescription for elastic Thomson scattering in electron-scatter…
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…
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…
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-…
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…
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…
Polarisation properties of X-ray emission from accreting supermassive black holes
Jakub Podgorný
This dissertation elaborates on X-ray polarisation features of astrophysical environments near accreting black holes. Although the work was originally assigned to supermassive blac…
X-ray polarization from parsec-scale components of active galactic nuclei: observational prospects
J. Podgorný, F. Marin, M. Dovčiak
We present a broad analysis of X-ray polarimetric observational prospects for radio-quiet active galactic nuclei (AGN), focusing on the role of parsec-scale components. We provide…
Spectral and polarization properties of reflected X-ray emission from black hole accretion discs
Jakub Podgorný, Michal Dovčiak, Frédéric Marin +2
X-ray polarimetric missions planned for this decade will significantly enhance our knowledge of compact accreting sources. Observations of the X-ray polarization signal from active…
