Scientific paper

I discuss current and future applications of pixel lensing: the microlensing
of unresolved stars. Pixel lensing is the tool of choice for studying the Macho
dark matter content of external galaxies like Andromeda (M31), and is at the
heart of an ambitious new proposal to undertake a census of low-mass stars and
brown dwarfs in the M31 bulge.
