The eROSITA X-ray telescope on SRG
P. Predehl, R. Andritschke, V. Arefiev +90
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the primary instrument on the Spectrum-Roentgen-Gamma (SRG) mission, which was successfully launched on July 1…
Simultaneous fits in ISIS on the example of GRO J1008-57
Matthias Kühnel, Sebastian Müller, Ingo Kreykenbohm +9
Parallel computing and steadily increasing computation speed have led to a new tool for analyzing multiple datasets and datatypes: fitting several datasets simultaneously. With thi…
The Goodness of Simultaneous Fits in ISIS
Matthias Kühnel, Sebastian Falkner, Christoph Grossberger +15
In a previous work, we introduced a tool for analyzing multiple datasets simultaneously, which has been implemented into ISIS. This tool was used to fit many spectra of X-ray binar…
The Gamma-Ray Emitting Radio-Loud Narrow-Line Seyfert 1 Galaxy PKS 2004-447 II. The Radio View
R. Schulz, A. Kreikenbohm, M. Kadler +20
Gamma-ray detected radio-loud narrow-line Seyfert 1 (g-NLS1) galaxies constitute a small but interesting sample of the gamma-ray loud AGN. The radio-loudest g-NLS1 known, PKS 2004-…
The Gamma-Ray Emitting Radio-Loud Narrow-Line Seyfert 1 Galaxy PKS 2004-447 I. The X-Ray View
Annika Kreikenbohm, Robert Schulz, Matthias Kadler +11
As part of the TANAMI multiwavelength progam, we discuss new X-ray observations of the -ray and radio-loud Narrow Line Seyfert galaxy (-NLS1) PKS 2004-447. The active galaxy…
The EVN view of the highly variable TeV active galaxy IC 310
R. Schulz, M. Kadler, E. Ros +9
Very-high-energy -ray observations of the active galaxy IC 310 with the MAGIC telescopes have revealed fast variability with doubling time scales of less than 4.8min. This impli…
TANAMI monitoring of Centaurus A: The complex dynamics in the inner parsec of an extragalactic jet
C. Müller, M. Kadler, R. Ojha +24
Centaurus A is the closest radio-loud active galaxy. Very Long Baseline Interferometry (VLBI) enables us to study the jet-counterjet system on milliarcsecond (mas) scales, providin…
TANAMI Blazars in the IceCube PeV Neutrino Fields
F. Krauß, M. Kadler, K. Mannheim +39
The IceCube Collaboration has announced the discovery of a neutrino flux in excess of the atmospheric background. Due to the steeply falling atmospheric background spectrum, events…
The unusual multiwavelength properties of the gamma-ray source PMNJ1603-4904
Cornelia Müller, M. Kadler, R. Ojha +27
We investigate the nature and classification of PMNJ1603-4904, a bright radio source close to the Galactic plane, which is associated with one of the brightest hard-spectrum gamma-…
mm-VLBI observations of the active galaxy 3C 111 in outburst
Robert Schulz, Matthias Kadler, Eduardo Ros +7
The broad-line radio galaxy 3C 111 exhibited a major flux density outburst in 2007. Here, we present imaging and preliminary kinematic results of the jet, based on three millimetre…
