We present the AGAPE astrometric and photometric catalogue of 1579 variable stars in a 14'x10' field centred on M31. This work is the first survey devoted to variable stars in the bulge of M31. [...]

The Point-Agape survey : No Need for Machos in M31 ?
/ POINT-AGAPE Collaboration
We have carried out a survey of the Andromeda galaxy for unresolved microlensing (pixel lensing). We present a subset of four short timescale microlensing candidates with high ratio of signal to noise, by imposing severe selection criteria: the source flux variation exceeds the flux of a R=21 magnitude star and the full-width half-maximum timescale is less than 25 days. [...]

A Candidate M31/M32 Intergalactic Microlensing Event
/ POINT-AGAPE Collaboration
We report the discovery of a microlensing candidate projected 2'54" from the center of M32, on the side closest to M31. The blue color (R-I= 0.00 +/- 0.14) of the source argues strongly that it lies in the disk of M31, while the proximity of the line of sight to M32 implies that this galaxy is the most likely host of the lens.

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. [...]

AGAPEROS : Searches for microlensing in the LMC with the Pixel Method; 2, Selection of possible microlensing events
/ Melchior, A.L. (Queen Mary, U. of London ; College de France) ; Afonso, C (CEA, DSM, Saclay ; DAPNIA, Saclay) ; Ansari, R (Orsay, LAL) ; Aubourg, E.

Astrophys.) ; Bouquet, A. (College de France) ; Brehin, S. (CEA, DSM, Saclay ; DAPNIA, Saclay) et al.
We apply the pixel method of analysis (sometimes called ``pixel lensing'') to a small subset of the EROS-1 microlensing observations of the bar of the Large Magellanic Cloud (LMC). The pixel method is designed to find microlensing events of unresolved source stars and had heretofore been applied only to M31 where essentially all sources are unresolved. [...]

AGAPEROS : Searches for microlensing in the LMC with the Pixel Method; 1, Data treatment and pixel light curves production
/ Melchior, A.-L. (Queen Mary, U. of London ; College de France ; Fermilab) ; Afonso, C. (DAPNIA, Saclay) ; Ansari, R. (Orsay, LAL) ; Aubourg, E. (DAPNIA, Saclay) ; Baillon, P. (CERN) ; Bareyre, P.

The presence and abundance of MAssive Compact Halo Objects (MACHOs) towards the Large Magellanic Cloud (LMC) can be studied with microlensing searches. The 10 events detected by the EROS and MACHO groups suggest that objects with 0.5 Mo could fill 50% of the dark halo. [...]
