XMM-Newton observations of the ultra-compact binary RX J1914+24
Gavin Ramsay, Pasi Hakala, Kinwah Wu +4
We present XMM-Newton observations of the 569 sec period system RX J1914+24 (V407 Vul). This period is believed to represent the binary orbital period making it an ultra-compact bi…
Compton Scattering of Fe KαLines from Accreting White Dwarfs
Z. Kuncic, K. Wu, J. G. Cullen
Compton scattering in the bulk accretion flow of the accretion column in magnetic cataclysmic variables (mCVs) can significantly shift photon energies in the X-ray emission lines r…
The star-forming environment of a ULX in NGC 4559: an optical study
Roberto Soria, Mark Cropper, Manfred Pakull +2
We have studied the candidate optical counterparts and the stellar population in the star-forming complex around a bright ULX in NGC4559, using HST/WFPC2, XMM-Newton/OM, and ground…
The Ultra-Luminous X-ray Source Population from the Chandra Archive of Galaxies
Douglas A. Swartz, Kajal K. Ghosh, Allyn F. Tennant +1
One hundred fifty-four discrete non-nuclear Ultra-Luminous X-ray (ULX) sources, with intrinsic X-ray luminosities >1e39 ergs/s, are identified in 82 galaxies observed with Chandra'…
XMM-Newton observations of polars in low accretion states
Gavin Ramsay, Mark Cropper, Kinwah Wu +3
We have made a series of snap-shot observations of 37 polars using XMM-Newton. We found that 16 of these systems were in a low, or much reduced, accretion state. Of those, 6 were n…
