A ULX in NGC 4559: a "mini-cartwheel" scenario?
Roberto Soria, Mark Cropper, Manfred Pakull
We have studied an ultraluminous X-ray source (ULX) in NGC 4559 with XMM-Newton, and its peculiar star-forming environment with HST/WFPC2. The X-ray source is one of the brightest…
Twisted accretion curtains in the intermediate polar FO Aquarii
P. A. Evans, Coel Hellier, Gavin Ramsay +1
We report on a ~37-ks XMM-Newton observation of the intermediate polar FO Aquarii, presenting X-ray and UV data from the EPIC and OM cameras. We find that the system has changed fr…
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…
XMM-Newton Observations of PSR B1706-44
Katherine E. McGowan, Silvia Zane, Mark Cropper +5
We report on the XMM-Newton observations of the young, 102 ms pulsar PSR B1706-44. We have found that both a blackbody plus power-law and a magnetized atmospheric model plus power-…
XMM-Newton observations of three short period polars: V347 Pav, GG Leo and EU UMa
Gavin Ramsay, Mark Cropper, K. O. Mason +2
We present phase-resolved XMM_Newton data of three short period polars: V347 Pav, GG Leo and EU UMa. All three systems show one dominant accretion region which is seen for approxim…
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…
