Orbital X-Ray Variability of the Microquasar LS 5039
V. Bosch-Ramon, J. M. Paredes, M. Ribo +3
The properties of the orbit and the donor star in the high mass X-ray binary microquasar LS 5039 indicate that accretion processes should mainly occur via a radiatively driven wind…
Observations of Selected AGN with H.E.S.S
F. Aharonian et al.
A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
Determination of stellar shape in microlensing event MOA 2002-BLG-33
N. J. Rattenbury, F. Abe, D. P. Bennett +30
We report a measurement of the shape of the source star in microlensing event MOA 2002-BLG-33. The lens for this event was a close binary whose centre-of-mass passed almost directl…
Further evidence for the presence of a neutron star in 4U 2206+54. INTEGRAL and VLA observations
P. Blay, M. Ribo, I. Negueruela +5
The majority of High Mass X-ray Binaries (HMXBs) behave as X-ray pulsars, revealing that they contain a magnetised neutron star. Among the four HMXBs not showing pulsations, and th…
Radiodetection of Cosmic Ray Extensive Air Showers
D. Ardouin, A. Belletoile, D. Charrier +12
We present the characteristics and performance of a demonstration experiment devoted to the observation of ultra high- energy cosmic ray extensive air showers using a radiodetectio…
Extracting clean supernova spectra
S. Blondin, J. R. Walsh, B. Leibundgut +1
We use a new technique to extract the spectrum of a supernova from that of the contaminating background of its host galaxy, and apply it to the specific case of high-redshift Type…
