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…
Destriping Polarised data
B. Revenu, F. Couchot, J. Delabrouille +1
We show how to take advantage of a circle scanning strategy, such as that planned for the Planck mission, to get rid of low frequency noises for polarised data.
AGAPE: a Microlensing Search for Dark Matter by Monitoring Pixels
P. Gondolo, R. Ansari, M. Auriere +13
AGAPE is an observational search of massive compact halo objects (MACHOs) in the direction of M31 by means of a novel method: the gravitational microlensing of unresolved stars. Th…
AGAPE, a microlensing search in the direction of M31: status Report
R. Ansari, M. Auriere, P. Baillon +13
A status report of the microlensing search by the pixel method in the direction of M31, on the 2 meter telescope at Pic du Midi is given. Pixels are stable to a level better than 0…
Microlensing by brown dwarfs: the case of dark clusters
Alain Bouquet, Jean Kaplan, Jean-Manuel Verschaeve
Experiments are looking for diffuse brown dwarfs in the dark galactic halo through the gravitational lens effect. If brown dwarfs are clumped in dark clusters, the event rate is no…
Detection of brown dwarfs by the micro-lensing of unresolved stars
Paul Baillon, Alain Bouquet, Yannick Giraud-Héraud +1
The presence of brown dwarfs in the dark galactic halo could be detected through their gravitational lensing effect and experiments under way monitor about one million stars to obs…
