A New Kind of Nova
J. L. Sokoloski, S. J. Kenyon, A. K. H. Kong +10
We performed extensive, multi-wavelength observations of the prototypical symbiotic star Z Andromedae between 2000 and 2003, during a large eruption. The rise to optical maximum oc…
GRS 1915+105: The first three months with INTEGRAL
D. C. Hannikainen, O. Vilhu, J. Rodriguez +19
GRS 1915+105 is being observed as part of an Open Time monitoring program with INTEGRAL. Three out of six observations from the monitoring program are presented here, in addition t…
Entropy Evolution of the Gas in Cooling Flow Clusters
Christian R. Kaiser, James J. Binney
We emphasise the importance of the gas entropy in studying the evolution of cluster gas evolving under the influence of radiative cooling. On this basis, we develop an analytical m…
AGN as cosmic thermostats
Christian R. Kaiser, Marcus Brueggen, James J. Binney
We present a simple analytical model and the results of numerical simulations supporting the idea of periodical heating of cluster gas by AGN outflows. We show why, under this assu…
Modelling Oscillations in GRS 1915+105 Jet Emission
Ross S. Collins, Christian R. Kaiser, Simon J. Cox
We have studied time variability in the flux from the flat spectrum synchrotron radiation of the Blandford & Konigl (1979) model for relativistic, conical jets. The resulting model…
Outbursts of Classical Symbiotics: Multi-Wavelength Observations of the 2000-2001 Outburst of Z Andromedae
J. L. Sokoloski, S. J. Kenyon, A. K. H. Kong +11
We describe the first results from a program of multi-wavelength monitoring of symbiotic binary stars in outburst. The prototypical symbiotic star Z Andromedae was observed extensi…
