An XMM-Newton view of the luminous X-ray source population of M101. (2004)
Journal Article
Jenkins, L., Roberts, T., Warwick, R., Kilgard, R., & Ward, M. (2004). An XMM-Newton view of the luminous X-ray source population of M101. Memorie Della Società Astronomica Italiana, 75(3),

We present the first results of an XMM n EPIC observation of the luminous X-ray source population in the face-on supergiant spiral galaxy M101. We have studied the X-ray spectral and temporal properties of the most luminous sources in M101 at the tim... Read More about An XMM-Newton view of the luminous X-ray source population of M101..

High-resolution imaging of the He II λ4686 emission line nebula associated with the ultraluminous X-ray source in Holmberg II (2004)
Journal Article
Kaaret, P., Ward, M., & Zezas, A. (2004). High-resolution imaging of the He II λ4686 emission line nebula associated with the ultraluminous X-ray source in Holmberg II. Monthly Notices of the Royal Astronomical Society, 351(3), L83-L88. https://doi.org/10.1111/j.1365-2966.2004.08020.x

We present Hubble Space Telescope images of the He iii region surrounding the bright X-ray source in the dwarf irregular galaxy Holmberg II. Using Chandra, we find a position for the X-ray source of (J2000) with an uncertainty of 0.6 arcsec. We ident...

Chandra observations of five ultraluminous X-ray sources in nearby galaxies (2004)
Journal Article
Roberts, T., Warwick, R., Ward, M., & Goad, M. (2004). Chandra observations of five ultraluminous X-ray sources in nearby galaxies. Monthly Notices of the Royal Astronomical Society, 349(4), 1193-1210. https://doi.org/10.1111/j.1365-2966.2004.07626.x

We report the results of a programme of dual-epoch Chandra ACIS-S observations of five ultraluminous X-ray sources (ULXs) in nearby spiral galaxies. All five ULXs are detected as unresolved, point-like X-ray sources by Chandra, though two have faded... Read More about Chandra observations of five ultraluminous X-ray sources in nearby galaxies.

An XMM-Newton view of M101 - I. The luminous X-ray source population. (2004)
Journal Article
Jenkins, L., Roberts, T., Warwick, R., Kilgard, R., & Ward, M. (2004). An XMM-Newton view of M101 - I. The luminous X-ray source population. Monthly Notices of the Royal Astronomical Society, 349(2), 404-424. https://doi.org/10.1111/j.1365-2966.2004.07546.x

We present the first results of an XMM–Newton EPIC observation of the luminous X-ray source population in the face-on supergiant spiral galaxy M101. We have studied the spectral and temporal properties of the 14 most luminous sources, all of which ha... Read More about An XMM-Newton view of M101 - I. The luminous X-ray source population..
