Cores and Cusps in the Dwarf Spheroidals
N. W. Evans, J. An, M. G. Walker
We consider the problem of determining the structure of the dark halo of nearby dwarf spheroidal galaxies (dSphs) from the spherical Jeans equations. Whether the dark halos are cus…
On Multiple Einstein Rings
M. C. Werner, J. An, N. W. Evans
A number of recent surveys for gravitational lenses have found examples of double Einstein rings. Here, we investigate analytically the occurrence of multiple Einstein rings. We pr…
Classical novae from the POINT-AGAPE microlensing survey of M31 -- II. Rate and statistical characteristics of the nova population
M. J. Darnley, M. F. Bode, E. Kerins +17
We report the results of our statistical study of the POINT-AGAPE CNe catalogue. The first Sloan and analysis of the MMRD relationship in M31 is performed using the resul…
Automated Detection of Classical Novae with Neural Networks
S. Feeney, V. Belokurov, N. W. Evans +9
The POINT-AGAPE collaboration surveyed M31 with the primary goal of optical detection of microlensing events, yet its data catalogue is also a prime source of lightcurves of variab…
POINT-AGAPE Pixel Lensing Survey of M31 : Evidence for a MACHO contribution to Galactic Halos
S. Calchi Novati, S. Paulin-Henriksson, J. An +15
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…
The POINT-AGAPE survey II: An Unrestricted Search for Microlensing Events towards M31
V. Belokurov, J. An, N. W. Evans +16
An automated search is carried out for microlensing events using a catalogue of 44554 variable superpixel lightcurves derived from our three-year monitoring program of M31. Each st…
