The thermal instability of the warm absorber in NGC 3783
R. W. Goosmann, T. Holczer, M. Mouchet +5
We model the observed X-ray spectral continuum shape, ionic column densities, and absorption measure distribution (AMD) of the warm absorber in the Seyfert galaxy NGC 3783. We assu…
High resolution X-ray spectroscopy of the Seyfert 1 Mrk841: insights into the warm absorber and warm emitter
A. L. Longinotti, E. Costantini, P. O. Petrucci +6
The Seyfert 1 galaxy Mrk841 was observed five times between 2001 and 2005 by the XMM-Newton X-ray observatory. The source is well known for showing spectral complexity in the varia…
Thermal instability in X-ray photoionized media in Active Galactic Nuclei: II. Role of the thermal conduction in warm absorber
B. Czerny, L. Chevallier, A. C. Goncalves +2
A photoionized gas under constant pressure can display a thermal instability, with three or more solutions for possible thermal equilibrium. A unique solution of the structure of t…
How to estimate the distance to the Warm Absorber in AGN from photoionized models
Agata Różańska, Izabela Kowalska, Anabela Goncalves
We present a method that allows us to estimate the distance from the continuum source located in the center of AGN to the highly ionized gas called warm absorber. We compute a set…
Thermal instabilities in Active Galactic Nuclei: the case of thin vs. thick ionized media
A. C. Goncalves, S. Collin, A. -M. Dumont
We have studied the thermal instabilities in the context of Active Galactic Nuclei (AGN), addressing the cases of thin and thick (stratified) X-ray illuminated media. For that, we…
Soft-excess in ULX spectra: disc emission or wind absorption?
A. C. Goncalves, R. Soria
We assess the claim that Ultra-luminous X-ray sources (ULXs) host intermediate-mass black holes (BH) by comparing the cool disc-blackbody model with a range of other models, namell…
