SLOTT-AGAPE (Systematic Lensing Observation at Toppo Telescope-Andromeda Gravitational Amplification Pixel Lensing Experiment) is a new collaboration project among international partners from England, France, Germany, Italy and Switzerland that intends to perform mi-crolensing observation by using M31 as target. The MACHOs search is made thanks to the pixel(More)
Aims. We seek to probe the Galactic bulge IMF starting from microlensing observations. Methods. We analyse the recent results of the microlensing campaigns carried out towards the Galactic bulge presented by the EROS, MACHO and OGLE collaborations. In particular, we study the duration distribution of the events. We assume a power law initial mass function,(More)
We study the possibility to detect extrasolar planets in M31 through pixel-lensing observations. Using a Monte Carlo approach, we select the physical parameters of the binary lens system, a star hosting a planet, and we calculate the pixel-lensing light curve taking into account the finite source effects. Indeed, their inclusion is crucial since the sources(More)
(2015). Spitzer microlens measurement of a massive remnant in a well-separated binary. ABSTRACT We report the detection and mass measurement of a binary lens OGLE-2015-BLG-1285La,b, with the more massive component having M 1 > 1.35 M e (80% probability). A main-sequence star in this mass range is ruled out by limits on blue light, meaning that a primary in(More)
— In the framework of the search of dark matter in galactic halos in form of massive compact halo object (MACHOs), we discuss the status of microlens-ing observations towards the Magellanic Clouds and the Andromeda galaxy, M31. The detection of a few microlensing events has been reported, but an unambiguous conclusion on the halo content in form on MACHOs(More)
The POINT-AGAPE collaboration is carrying out a search for gravitational microlensing toward M31 to reveal galactic dark matter in the form of MACHOs (Massive Astrophysical Compact Halo Objects) in the halos of the Milky Way and M31. A high-threshold analysis of 3 years of data yields 6 bright, short–duration microlensing events, which are confronted to a(More)
For the purposes of identifying microlensing events, the POINT-AGAPE collaboration has been monitoring the Andromeda galaxy (M31) for three seasons (1999-2001) with the Wide Field Camera on the Isaac Newton Telescope. In each season, data are taken for one hour per night for roughly sixty nights during the six months that M31 is visible. The two 33 ′ ×33 ′(More)
