The ROSAT Deep Cluster Survey: Constraints on Cosmology
S. Borgani, P. Rosati, R. Della Ceca +2
We use the ROSAT Deep Cluster Survey (RDCS) to trace the evolution of the cluster abundance out to and constrain cosmological models. We resort to a phenomenological…
The First Five Minutes of a Core Collapse Supernova: Multidimensional Hydrodynamic Models
K. Kifonidis, T. Plewa, H. -Th. Janka +1
We present results of high-resolution two-dimensional simulations which follow the first five minutes of a core collapse supernova explosion in a 15 solar mass blue supergiant prog…
Reflection and noise in Cygnus X-1
M. Gilfanov, E. Churazov, M. Revnivtsev
We analyzed RXTE/PCA observations of Cyg X-1 from 1996-1998. We found a tight correlation between the characteristic noise frequencies (e.g. the break frequency nu_br) and the spec…
Survey of Large Planetary Nebulae in Decay
Thomas Rauch, Elise Furlan, Florian Kerber +1
The Planetary Nebulae (PNe) return nuclear processed stellar material back to the interstellar medium (ISM) and thus have an important influence on the chemical evolution of our Ga…
New bright soft X-ray selected ROSAT AGN II. Optical emission line properties
D. Grupe, K. Beuermann, K. Mannheim +1
We present the emission line properties of a sample of 76 bright soft X-ray selected ROSAT Active Galactic Nuclei. All optical counterparts are Seyfert 1 galaxies with rather narro…
Further Evidence that Some Quasars Originate in Nearby Galaxies: NGC3628
Eric Flesch, Halton Arp
NGC3628 is a well-studied starburst/low level AGN galaxy in the Leo Triplet noted for its extensive outgassed plumes of neutral hydrogen. Catalogued QSOs are shown to be concentrat…
