TL;DR: In this article, an analysis of the maximum magnitude versus rate of decline (MMRD) relationship in M31 is performed using the resulting POINT-AGAPE CN catalogue, and good fits are produced to the MMRD in two filters.

TL;DR: In this article, the authors report the results of their statistical study of the POINT-AGAPE CNe catalogue and conclude that the true global nova rate of M31 is at least 50% higher than was previously thought.

TL;DR: In this paper, the locations, periods and amplitudes of 35414 variable stars in M31 were calculated as a byproduct of the Point-AGAPE collaboration's microlensing search.

The Anomaly in the Candidate Microlensing Event PA-99-N2
J. An,Nick Evans,Eamonn Kerins,P. Baillon,S. Calchi-Novati,Bernard Carr,M. Creze,Y. Giraud-Heraud,Andrew Gould,Paul C. Hewett,Ph. Jetzer,J. Kaplan,S. Paulin-Henriksson,Stephen Smartt,Yiannis Tsapras,David Valls-Gabaud +15 more
TL;DR: In this article, the authors explore a number of possible explanations, including correlations with the seeing, the parallax effect and a binary lens, and find that the observations are consistent with an unresolved RGB or AGB star in M31 being microlensed by a binar lens.

Classical novae from the POINT-AGAPE microlensing survey of M31 -- I. The nova catalogue
M. J. Darnley,Michael F. Bode,E. Kerins,A. M. Newsam,Jin H. An,P. Baillon,S. Calchi Novati,Bernard Carr,M. Creze,Nick Evans,Y. Giraud-Heraud,Andrew Gould,Paul C. Hewett,Ph. Jetzer,J. Kaplan,S. Paulin-Henriksson,Stephen J. Smartt,C. S. Stalin,Yiannis Tsapras +18 more
TL;DR: The POINT-AGAPE survey is an optical search for gravitational microlensing events towards the Andromeda Galaxy (M31). As well as micro-lensing, the survey is sensitive to many different classes of variable stars and transients.
