Reconstruction of HI power spectra with radio-interferometers to study dark energy
R. Ansari, J. -M. Le Goff, Ch. Magneville +5
Among the tools available for the study of the dark energy driving the expansion of the Universe, Baryon Acoustic Oscillations (BAO) and their effects on the matter power spectrum…
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…
A Proposal to Search for Transparent Hidden Matter Using Optical Scintillation
Marc Moniez
It is proposed to search for scintillation of extragalactic sources through the last unknown baryonic structures. Appropriate observation of the scintillation process described her…
Study of a Strategy for Parallax Microlensing Detection Towards the Magellanic Clouds
S. Rahvar, M. Moniez, R. Ansari +1
In this article, we have investigated the possibility to distinguish between different galactic models through the microlensing parallax studies. We show that a systematic search f…
Possible use of the dedicated MARLY one meter telescope for intensive supernovae studies
M. Moniez, O. Perdereau
The EROS2 microlensing search will end at the end of 2002. Apart of this microlensing search, EROS has discovered ~70 supernovae during 8 periods partially dedicated to a SN search…
AgapeZ1: a Large Amplification Microlensing Event or an Odd Variable Star Towards the Inner Bulge of M31
R. Ansari, M. Auriere, P. Baillon +14
AgapeZ1 is the brightest and the shortest duration microlensing candidate event found in the Agape data. It occured only 42" from the center of M31. Our photometry shows that the h…
