Fast variability of tera-electron volt gamma rays from the radio galaxy M87 (2006)
Journal Article
The detection of fast variations of the tera–electron volt (TeV) (1012 eV) -ray flux, on time scales of days, from the nearby radio galaxy M87 is reported. These variations are about 10 times as fast as those observed in any other wave band and imply... Read More about Fast variability of tera-electron volt gamma rays from the radio galaxy M87.

Chandra monitoring observations of the ultraluminous X-ray source NGC 5204 X-1. (2006)
Journal Article
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..

Discovery of very high energy γ-ray emission from the BL Lacertae object H 2356-309 with the HESS Cherenkov telescopes (2006)
Journal Article
The extreme synchrotron BL Lac object H 2356-309, located at a redshift of z = 0.165, was observed from June to December 2004 with a total exposure of $\approx$40 h live-time with the HESS (High Energy Stereoscopic System) array of atmospheric-Cheren...

Astronomy & Astrophysics, 448(2), L43-L47. https://doi.org/10.1051/0004-6361%3A200600014The 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...
