Multi-wavelength study of Mrk 421 during a TeV flare
A. Gokus, A. Kreikenbohm, K. Leiter +31
The blazar Mrk 421 shows frequent, short flares in the TeV energy regime. Due to the fast nature of such episodes, we often fail to obtain sufficient simultaneous information about…
Hunting for the nature of the enigmatic narrow-line Seyfert 1 galaxy PKS 2004-447
M. Berton, G. Peluso, P. Marziani +19
Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that, in some cases, can harbor powerful relativistic jets. One of them, PKS 2004-447, shows gamma…
The EXTraS Project: Exploring the X-ray transient and variable sky
A. De Luca, R. Salvaterra, A. Belfiore +29
Temporal variability in flux and spectral shape is ubiquitous in the X-ray sky and carries crucial information about the nature and emission physics of the sources. The EPIC instru…
Virtual Data Cosmos -- Information Design in Modern Astronomy
Annika Kreikenbohm
Where do cosmic X-rays come from? Every new unidentified X-ray source could potentially revolutionize our understanding of the universe. The international collaborative astronomy p…
3D mapping of the neutral X-ray absorption in the local interstellar medium: The Gaia and XMM-Newton synergy
Efraín Gatuzz, S. Rezaei Kh., Timothy R. Kallman +4
We present a three-dimensional map of the hydrogen density distribution in the Galactic interstellar medium. The hydrogen equivalent column densities were obtained from the Explori…
Extended X-ray emission in PKS 1718649
T. Beuchert, A. Rodríguez-Ardila, V. A. Moss +15
PKS 1718649 is one of the closest and most comprehensively studied candidates of a young active galactic nucleus (AGN) that is still embedded in its optical host galaxy. The com…
