New XMM-Newton analysis of three bright X-ray sources in M31 globular clusters, including a new black hole candidate
R. Barnard, H. Stiele, D. Hatzidimitriou +6
We present detailed analysis of three globular cluster X-ray sources in the XMM-Newton extended survey of M31. The X-ray counterpart to the M31 globular cluster Bo 45 (XBo 45) was…
NGC300 X-1 and IC10 X-1: a new breed of black hole binary?
R. Barnard, J. S. Clark, U. C. Kolb
[ABRIDGED] IC10 X-1 has recently been confirmed as a black hole (BH) + Wolf-Rayet (WR) X-ray binary, and NGC300 X-1 is thought to be. IC10 X-1 and NGC300 X-1 have similar X-ray pro…
An X-ray spectral survey of the disc of M31 with XMM-Newton
L. Shaw Greening, R. Barnard, U. Kolb +2
We present the results of a complete spectral survey of the X-ray point sources detected in five XMM-Newton observations along the major axis of M31 but avoiding the central bulge,…
A multi-coloured survey of NGC 253 with XMM-Newton: testing the methods used for creating luminosity functions from low-count data
R. Barnard, L. Shaw Greening, U. Kolb
NGC 253 is a local, star-bursting spiral galaxy with strong X-ray emission from hot gas, as well as many point sources. We have conducted a spectral survey of the X-ray population…
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…
A Multi-coloured survey of NGC 253 with XMM-Newton
R. Barnard, L. Shaw Greening, U. Kolb
There is a large body of work that has used the excellent Chandra observations of nearby galaxies with neglible low mass X-ray binary (LMXB) populations. This has culminated in a `…
On the artificial nature of aperiodic variability in XMM-Newton observations of M31 X-ray sources and the ultraluminous X-ray source NGC 4559 ULX-7
R. Barnard, S. Trudolyubov, U. C. Kolb +3
Context: Power density spectra (PDS) that are characteristic of low mass X-ray binaries (LMXBs) have been previously reported for M31 X-ray sources, observed by XMM-Newton. However…
Cumulative luminosity functions of the X-ray point source population in M31
L. Shaw Greening, C. Tonkin, R. Barnard +2
We present preliminary results from a detailed analysis of the X-ray point sources in the XMM-Newton survey of M31. These sources are expected to be mostly X-ray binaries. We have…
XMM-Newton reveals ~100 new LMXBs in M31 from variability studies
R. Barnard, L. Shaw Greening, C. Tonkin +2
We have conducted a survey of X-ray sources in XMM-Newton observations of M31, examining their power density spectra (PDS) and spectral energy distributions (SEDs). Our automated s…
The X-ray Properties of M101 ULX-1 = CXOKM101 J140332.74+542102
K. Mukai, M. Still, R. H. D. Corbet +2
We report our analysis of X-ray data on M101 ULX-1, concentrating on high state Chandra and XMM-Newton observations. We find that the high state of M101 ULX-1 may have a preferred…
Discovery of disc precession in the M31 dipping X-ray binary Bo 158
R. Barnard, S. B. Foulkes, C. A. Haswell +3
We present results from three XMM-Newton observations of the M31 low mass X-ray binary XMMU J004314.4+410726.3 (Bo 158), spaced over 3 days in 2004, July. Bo 158 was the first dipp…
Identifying a black hole X-ray transient in M31 with XMM-Newton and Chandra
R. Barnard, U. Kolb, J. P. Osborne
Stochastic variability in two out of four XMM-Newton observations of XMMU J004303+4115 along with its power spectra and X-ray luminosities suggest a low-mass X-ray binary (LMXB) wi…
RX J0042.3+4115: a stellar mass black hole binary identified in M31
R. Barnard, J. P. Osborne, U. Kolb +1
Four XMM-Newton X-ray observations of the central region of the Andromeda Galaxy (M31) have revealed an X-ray source that varies in luminosity over \~1--3, 10^{38} erg s^{-1} betwe…
