The Discovery of an X-ray/UV Stellar Flare from the Late-K/Early-M Dwarf LMC 335
B. T. H. Tsang, C. S. J. Pun, R. Di Stefano +2
We report the discovery of an X-ray/UV stellar flare from the source LMC 335, captured by XMM-Newton in the field of the Large Magellanic Cloud. The flare event was recorded contin…
The deep XMM-Newton Survey of M 31
H. Stiele, W. Pietsch, F. Haberl +5
Aims. M 31 has been completely imaged for the first time obtaining a luminosity lower limit ~10^35 erg s-1 in the 0.2-4.5 keV band. Our XMM-Newton EPIC survey combines archival obs…
The first two transient supersoft X-ray sources in M 31 globular clusters and the connection to classical novae
M. Henze, W. Pietsch, F. Haberl +12
Classical novae (CNe) have been found to represent the major class of supersoft X-ray sources (SSS) in our neighbour galaxy M 31. We determine properties and evolution of the two f…
An extremely luminous X-ray outburst at the birth of a supernova
A. M. Soderberg, E. Berger, K. L. Page +40
Massive stars end their short lives in spectacular explosions, supernovae, that synthesize new elements and drive galaxy evolution. Throughout history supernovae were discovered ch…
A deep XMM-Newton survey of M 31
H. Stiele, W. Pietsch, F. Haberl
The deep homogeneous survey of the large Local-Group spiral galaxy M 31 is a milestone project for X-ray astronomy, as it allows a detailed X-ray inventory of an archetypal low-sta…
The Spectrum of the Black Hole X-ray Nova V404 Cygni in Quiescence as Measured by XMM-Newton
C. K. Bradley, R. I. Hynes, A. K. H. Kong +3
We present XMM observations of the black hole X-ray nova V404 Cygni in quiescence. Its quiescent spectrum can be best fitted by a simple power-law with slope 2. The spectra are con…
