Chandra monitoring observations of the ultraluminous X-ray source NGC 5204 X-1. (2006)
Journal Article
Roberts, T., Kilgard, R., Warwick, R., Goad, M., & Ward, M. (2006). Chandra monitoring observations of the ultraluminous X-ray source NGC 5204 X-1. Monthly Notices of the Royal Astronomical Society, 371(4), 1877-1890. https://doi.org/10.1111/j.1365-2966.2006.10821.x

We report the results of a two-month campaign conducted with the Chandra X-ray observatory to monitor the ultraluminous X-ray source (ULX) NGC 5204 X-1. This was composed of a 50-ks observation, followed by ten 5-ks follow-ups spaced initially at ∼3,... Read More about Chandra monitoring observations of the ultraluminous X-ray source NGC 5204 X-1..

First detection of a VHE gamma-ray spectral maximum from a cosmicsource: HESS discovery of the Vela X nebula (2006)
Journal Article
Aharonian, F., Akhperjanian, A., Bazer-Bachi, A., Beilicke, M., Benbow, W., Berge, D., …Ward, M. (2006). First detection of a VHE gamma-ray spectral maximum from a cosmicsource: HESS discovery of the Vela X nebula. Astronomy & Astrophysics, 448(2), L43-L47. https://doi.org/10.1051/0004-6361%3A200600014

The Vela supernova remnant (SNR) is a complex region containing a number of sources of non-thermal radiation. The inner section of this SNR, within 2 degrees of the pulsar PSR B0833-45 , has been observed by the HESS $\gamma$-ray atmospheric Cherenko...
