The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. [...]

POINT-AGAPE Pixel Lensing Survey of M31 : Evidence for a MACHO contribution to Galactic Halos / Calchi Novati, Sebastiano ; Paulin-Henriksson, S. ; An, J. ; Baillon, P. ; Belokurov, V. ; Carr, Bernard J. ; Creze, M. ; Evans, N.W. ; Giraud-Heraud, Y. ; Gould, A. et al.
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 simulation of the observations and the analysis. [...]

The POINT-AGAPE survey is an optical search for gravitational microlensing events towards the Andromeda Galaxy (M31). As well as microlensing, the survey is sensitive to many different classes of variable stars and transients. [...]

The POINT-AGAPE Survey I: The Variable Stars in M31 / An Jun Hong ; Evans, y N W ; Hewett, P C ; Baillon, Paul ; Calchi-Novati, S ; Carr, B J ; Creze, M ; Giraud-Héraud, Yannick ; Gould, A ; Jetzer, P et al.
The POINT-AGAPE collaboration has been monitoring M31 for three seasons 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 Anomaly in the Candidate Microlensing Event PA-99-N2 / POINT-AGAPE Collaboration
The lightcurve of PA-99-N2, one of the recently announced microlensing candidates towards M31, shows small deviations from the standard Paczynski form. We explore a number of possible explanations, including correlations with the seeing, the parallax effect and a binary lens. [...]

Microlensing search towards M31 / Calchi Novati, S. ; Iovane, G. (Salerno U. ; INFN, Salerno) ; Marino, A.A. (Capodimonte Observ. ; INFN, Salerno) ; Auriere, M. (Midi-Pyrenees Observ.) ; Baillon, P.

(Salerno U. ; INFN, Salerno) et al.
We present the first results of the analysis of data collected during the 1998-99 observational campaign at the 1.3 meter McGraw-Hill Telescope, towards the Andromeda galaxy (M31), aimed to the detection of gravitational microlensing effects as a probe of the presence of dark matter in our and in M31 halo. The analysis is performed using the pixel lensing technique, which consists in the study of flux variations of unresolved sources and has been proposed and implemented by the AGAPE collaboration.
