Probable intermediate mass black holes in NGC4559: XMM-Newton spectral and timing constraints
Mark Cropper, Roberto Soria, Richard F. Mushotzky +3
We have examined X-ray and optical observations of two ultra-luminous X-ray sources, X7 and X10 in NGC4559, using XMM-Newton, Chandra and HST. The UV/X-ray luminosity of X7 exceeds…
Spin up in RX J0806+15 - the shortest period binary
Pasi Hakala, Gavin Ramsay, Kinwah Wu +4
RX J0806+15 has recently been identified as the binary system with the shortest known orbital period. We present a series of observations of RX J0806+15 including new optical obser…
Electron-cyclotron maser emission from white-dwarf pairs and white-dwarf planetary systems
Andrew J. Willes, Kinwah Wu
By analogy to Jovian radio emissions powered by the electromagnetic interaction between Jupiter and its moons, we propose that close magnetic-nonmagnetic white-dwarf pairs and whit…
The radio flaring behaviour of GRO J1655-40: an analogy with extragalactic radio sources?
J. A. Stevens, D. C. Hannikainen, Kinwah Wu +2
At radio frequencies, the current evidence for the microquasar-quasar connection is based on imaging observations showing that relativistic outflows/jets are found in both classes…
