Dust-driven wind as a model of Broad Absorption Line quasars
Mohammad Hassan Naddaf, Mary Loli Martinez-Aldama, Paola Marziani +3
We test a scenario claiming that the broad absorption line (BAL) phenomenon in quasars (QSOs) is not a temporary stage of their life. In this scenario, we see the BAL effect only i…
A possible mechanism for multiple changing look phenomenon in Active Galactic Nuclei
M. Sniegowska, B. Czerny, E. Bon +1
Changing-look phenomenon observed now in a growing number of active galaxies challenges our understanding of the accretion process close to a black hole. We propose a simple explan…
Increasing the Discovery Space in Astrophysics - A Collation of Six Submitted White Papers
G. Fabbiano, M. Elvis, A. Accomazzi +46
We write in response to the call from the 2020 Decadal Survey to submit white papers illustrating the most pressing scientific questions in astrophysics for the coming decade. We p…
What shapes the Absorption Measure Distribution in AGN outflows
T. P. Adhikari, A. Różańska, K. Hryniewicz +2
The Absorption Measure Distribution (AMD) in the X-ray outflows of Seyfert active galactic nuclei (AGN) describes the distribution of absorbing column density as a function of ioni…
On the warm absorber in AGN outflow
T. P. Adhikari, A. Rozanska, M. Sobolewska +1
Warm absorber (WA) is an ionised gas present in the line of sight to the AGN central engine. The effect of the absorber is imprinted in the absorption lines observed in X-ray spect…
The mass of the black hole in RE J1034+396
B. Czerny, B. You, A. Kurcz +6
The black hole mass measurement in active galaxies is a challenge, particularly in sources where the reverberation method cannot be applied. We aim to determine the black hole mass…
