XMM-Newton observations of the first unidentified TeV gamma-ray source TeV J2032+4130
D. Horns, A. I. D. Hoffmann, A. Santangelo +2
(abridged) The first unidentified very high energy gamma ray source (TeV J2032+4130) in the Cygnus region has been the subject of intensive search for a counterpart source at other…
X-RED: A Satellite Mission Concept To Detect Early Universe Gamma Ray Bursts
Mirko Krumpe, Deirdre Coffey, Georg Egger +14
Gamma ray bursts (GRBs) are the most energetic eruptions known in the Universe. Instruments such as Compton-GRO/BATSE and the GRB monitor on BeppoSAX have detected more than 2700 G…
Light and heavy metal abundances in hot central stars of planetary nebulae
K. Werner, A. I. D. Hoffmann, D. Jahn +5
We present new results from our spectral analyses of very hot central stars achieved since the last IAU Symposium on planetary nebulae held in Canberra 2001. The analyses are mainl…
Iron Abundance in Hydrogen-Rich Central Stars of Planetary Nebulae
A. I. D. Hoffmann, I. Traulsen, T. Rauch +3
We report on an on-going analysis of high-resolution UV spectra of hot hydrogen-rich central stars of planetary nebulae (CSPN), obtained with the Hubble Space Telescope and FUSE. S…
HST and FUSE Spectroscopy of Hot Hydrogen-Rich Central Stars of Planetary Nebulae
I. Traulsen, A. I. D. Hoffmann, T. Rauch +3
High-resolution UV spectra, obtained with HST and FUSE, enable us to analyse hot hydrogen-rich central stars in detail. Up to now, optical hydrogen and helium lines have been used…
