XMM-Newton observations of Sagittarius A East
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle +1
We present an analysis of a recent XMM-Newton observation of Sgr A East, a supernova remnant located close to the Galactic Centre. Very high quality X-ray spectra reveal many emiss…
An XMM-Newton view of M101: I. The luminous X-ray source population
L. P. Jenkins, T. P. Roberts, R. S. Warwick +2
We present the first results of an XMM-Newton EPIC observation of the luminous X-ray source population in the supergiant spiral galaxy M101. We have studied the properties of the f…
A new population of X-ray transients in the Galactic Centre
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle +1
A comparison of the XMM-Newton and Chandra Galactic Centre (GC) Surveys has revealed two faint X-ray transients with contrasting properties. The X-ray spectrum of XMM J174544-2913.…
Sgr A East and its surroundings observed in X-rays
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle
We report the results of an XMM-Newton observation of Sgr A East and its surroundings. The X-ray spectrum of Sgr A East is well represented with a two-temperature plasma model with…
On characterising the variability properties of X-ray light curves from active galaxies
S. Vaughan, R. Edelson, R. S. Warwick +1
We review some practical aspects of measuring the amplitude of variability in `red noise' light curves typical of those from Active Galactic Nuclei (AGN). The quantities commonly u…
XMM-Newton observation of the brightest X-ray flare detected so far from SgrA*
D. Porquet, P. Predehl, B. Aschenbach +5
We report the high S/N observation on October 3, 2002 with XMM-Newton of the brightest X-ray flare detected so far from SgrA* with a duration shorter than one hour (~ 2.7 ks). The…
