The multi-phase environment in the centre of Centaurus A
A. Borkar, T. P. Adhikari, A. Różańska +6
We study the multi-phase medium in the vicinity of the active galactic nucleus Centaurus A (Cen A). Combined high-resolution observations with the ALMA and Chandra observatories in…
Accurate Treatment of Comptonization in X-ray Illuminated Accretion Disks
Javier A. García, Ekaterina Sokolova-Lapa, Thomas Dauser +5
A large fraction of accreting black hole and neutron stars systems present clear evidence of the reprocessing of X-rays in the atmosphere of an optically-thick accretion disk. The…
Incoherent fast variability of X-ray obscurers. The case of NGC 3783
B. De Marco, T. P. Adhikari, G. Ponti +22
Context. Obscuration events caused by outflowing clumps or streams of high column density, low ionisation gas, heavily absorbing the X-ray continuum, have been witnessed in a numbe…
The high energy universe at ultra-high resolution: the power and promise of X-ray interferometry
Phil Uttley, Roland den Hartog, Cosimo Bambi +24
We propose the development of X-ray interferometry (XRI), to reveal the universe at high energies with ultra-high spatial resolution. With baselines which can be accommodated on a…
Orientation of the crescent image of M 87*
Krzysztof Nalewajko, Marek Sikora, Agata Różańska
The first image of the black hole (BH) M 87* obtained by the Event Horizon Telescope (EHT) has the shape of a crescent extending from the E to WSW position angles, while the observ…
Warm and thick corona for magnetically supported disk in GBHB
Dominik Gronkiewicz, Agata Różańska
This paper is devoted to self-consistent modeling of the magnetically supported accretion disk with optically thick warm corona based on first principles. In our model, we consider…
