Tidal disruption events and quasi periodic eruptions
Natalie A. Webb, Didier Barret, Olivier Godet +4
Tidal disruption events (TDEs) occur when a star passes close to a massive black hole, so that the tidal forces of the black hole exceed the binding energy of a star and cause it t…
XMM2ATHENA, the H2020 project to improve XMM-Newton analysis software and prepare for Athena
Natalie A. Webb, Francisco J. Carrera, Axel Schwope +31
XMM-Newton, a European Space Agency observatory, has been observing the X-ray, ultra-violet and optical sky for 23 years. During this time, astronomy has evolved from mainly studyi…
On the diversity of the jet production efficiency in Swift/BAT AGNs
Katarzyna Rusinek, Marek Sikora, Dorota Kozieł-Wierzbowska +1
We address the very large diversity of the jet production efficiency in active galactic nuclei (AGNs) by using data on low redshift AGNs selected from the Swift/BAT catalog and hav…
Long-term optical spectroscopic variations in blazar 3C 454.3
Krzysztof Nalewajko, Alok C. Gupta, Mai Liao +3
Characterisation of the long-term variations in the broad line region in a luminous blazar, where Comptonisation of broad-line emission within a relativistic jet is the standard sc…
Comparison of SEDs of very massive radio-loud and radio-quiet AGN
Maitrayee Gupta, Marek Sikora, Katarzyna Rusinek
The main objective of this work is to establish and interpret the dominant spectral components and their differences in radio-loud (RL) and radio-quiet (RQ) AGN with very massive b…
Comparison of hard X-ray spectra of luminous radio galaxies and their radio-quiet counterparts
Maitrayee Gupta, Marek Sikora, Katarzyna Rusinek +1
We study the differences in X-ray properties of luminous radio galaxies and their radio-quiet counterparts. In order to avoid biases associated with the dependence of X-ray propert…
