A Huge Drop in X-ray Luminosity of the Non-Active Galaxy RXJ1242.6-1119A, and First Post-Flare Spectrum - Testing the Tidal Disruption Scenario
S. Komossa, J. Halpern, N. Schartel +3
It has been suggested that an unavoidable consequence of the existence of supermassive black holes, and the best diagnostic of their presence in non-active galaxies, would be occas…
QZ Serpentis: A Dwarf Nova with a 2-Hour Orbital Period and an Anomalously Hot, Bright Secondary Star
J. R. Thorstensen, W. H. Fenton, J. O. Patterson +3
We present spectroscopy and time-series photometry of the dwarf nova QZ Ser. The spectrum shows a rich absorption line spectrum of type K4 +- 2. K-type secondary stars are generall…
A Possible X-ray and Radio Counterpart of the High-Energy Gamma-ray Source 3EG J2227+6122
J. P. Halpern, E. V. Gotthelf, K. M. Leighly +1
The identity of the persistent EGRET sources in the Galactic plane is largely a mystery. For one of these, 3EG J2227+6122, our complete census of X-ray and radio sources in its err…
