Irradiation models for ULXs and fits to optical data
C. M. Copperwheat, M. Cropper, R. Soria +1
We have constructed a model which describes the optical emission from ultraluminous X-ray sources (ULXs), and have used it to constrain the parameters of seven ULX systems. Our mod…
X-ray flares from the ultra-luminous X-ray source in NGC 5408
R. Soria, C. Motch, A. M. Read +1
We have studied an ultra-luminous X-ray source (ULX) in the dwarf galaxy NGC 5408 with a series of XMM-Newton observations, between 2001 July and 2003 January. We find that its X-r…
XMM-Newton RGS spectroscopy of LMC X-3
M. J. Page, R. Soria, K. Wu +3
We present soft X-ray spectroscopy of the black hole binary LMC X-3 from the XMM-Newton Reflection Grating Spectrometer. The observations span the full range of spectral states see…
X-ray emission line gas in the LINER galaxy M81
M. J. Page, A. A. Breeveld, R. Soria +5
We present the soft X-ray spectrum of the LINER galaxy M81 derived from a long observation with the XMM RGS. The spectrum is dominated by continuum emission from the active nucleus…
X-ray sources in the starburst spiral galaxy M83: nuclear region and discrete source population
Roberto Soria, Kinwah Wu
Chandra has resolved the starburst nuclear region of the face-on grand-design spiral M83. Eighty-one point sources are detected above 3.5 sigma in the ACIS S3 image, and 15 of them…
