Searching for similarities in the accretion flow of Seyfert 1 galaxies and cataclysmic variables based on flare profiles of IRAS 13224-3809, 1H 0707-495, Mrk 766 and MV Lyr
A. Dobrotka, H. Negoro, P. Bezak
AIMS: We studied fast variability of three selected AGNs, IRAS 13224-3809, 1H 0707-495 and Mrk 766, and the cataclysmic variable MV Lyr observed by XMM-Newton and Kepler spacecraft…
Multicomponent Power Density Spectra of Kepler AGNs, an instrumental artifact or a physical origin?
A. Dobrotka, P. Bezak, M. Revalski +1
We analysed the light curves of four active galactic nuclei (AGN) from the Kepler field, and find multicomponent power density spectra with characteristic frequencies that are surp…
New structures of Power Density Spectra for four Kepler AGNs
A. Dobrotka, V. Antonuccio-Delogu, I. Bajcicakova
Many nearby AGNs display a significant short-term variability. In this work we re-analyze photometric data of four active galactic nuclei observed by Kepler in order to study the f…
Obscuration effects in Super-Soft-Source X-ray spectra
J. -U. Ness, J. P. Osborne, M. Henze +11
Super-Soft-Source (SSS) X-ray spectra are blackbody-like spectra with effective temperatures ~3-7x10^5 K and luminosities of 10^{35-38} erg/s. SSS grating spectra display atmospher…
From X-ray dips to eclipse: Witnessing disk reformation in the recurrent nova USco
J. -U. Ness, B. E. Schaefer, A. Dobrotka +9
The 10th recorded outburst of the recurrent eclipsing nova USco was observed simultaneously in X-ray, UV, and optical by XMM-Newton on days 22.9 and 34.9 after outburst. Two full p…
