A massive x-ray outflow from the quasar PDS 456 (2003)
Journal Article
Reeves, J., O'Brien, P., & Ward, M. (2003). A massive x-ray outflow from the quasar PDS 456. Astrophysical Journal Letters, 593(2), L65-L68. https://doi.org/10.1086/378218

We report on XMM-Newton spectroscopic observations of the luminous radio-quiet quasar PDS 456. The hard X-ray spectrum of PDS 456 shows a deep absorption trough (constituting 50% of the continuum) at energies above 7 keV in the quasar rest frame, whi...

The unusual supernova remnant surrounding the ultraluminous X-ray source IC 342 X-1 (2003)
Journal Article
Roberts, T., Goad, M., Ward, M., & Warwick, R. (2003). The unusual supernova remnant surrounding the ultraluminous X-ray source IC 342 X-1. Monthly Notices of the Royal Astronomical Society, 342(3), 709-714. https://doi.org/10.1046/j.1365-8711.2003.06593.x

We report the results of an observation of a large-diameter (110 pc) supernova remnant (SNR) found to encircle the position of the ultraluminous X-ray source (ULX) IC 342 X-1. The inferred initial energy input to the SNR is at least 2-3 times greater... Read More about The unusual supernova remnant surrounding the ultraluminous X-ray source IC 342 X-1.

A Chandra observation of the interacting pair of galaxies NGC 4485/4490 (2002)
Journal Article
Roberts, T., Warwick, R., Ward, M., & Murray, S. (2002). A Chandra observation of the interacting pair of galaxies NGC 4485/4490. Monthly Notices of the Royal Astronomical Society, 337(2), 677-692. https://doi.org/10.1046/j.1365-8711.2002.05950.x

We report the results of a 20-ks Chandra ACIS-S observation of the galaxy pair NGC 4485/4490. This is an interacting system containing a late-type spiral with an enhanced star formation rate (NGC 4490), and an irregular companion that possesses a dis...

Chandra observations of the luminous infrared galaxy NGC 3256 (2002)
Journal Article
Lira, P., Ward, M., Zezas, A., Alonso-Herrero, A., & Ueno, S. (2002). Chandra observations of the luminous infrared galaxy NGC 3256. Monthly Notices of the Royal Astronomical Society, 330(2), 259-278. https://doi.org/10.1046/j.1365-8711.2002.05014.x

We present a detailed analysis of high-resolution Chandra observations of the merger system NGC 3256, the most infrared-luminous galaxy in the nearby universe. The X-ray data show that several discrete sources embedded in complex diffuse emission con... Read More about Chandra observations of the luminous infrared galaxy NGC 3256.
