Lighting up the dark and dim in the Andromeda Galaxy
Eamonn Kerins
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…
MACHOs and the clouds of uncertainty
Eamonn Kerins
I review proposals for explaining the current gravitational microlensing results from the EROS and MACHO surveys towards the Magellanic Clouds. Solutions involving massive compact…
Searching for MACHOs in Andromeda with INT
Eamonn Kerins
Two teams are using the Isaac Newton Telescope to conduct a microlensing search for massive compact halo objects (MACHOs) in Andromeda. We discuss both the motivation of the survey…
MACHO versus HST: how bright can dark matter be?
E. J. Kerins
Recent results from gravitational microlensing experiments, such as MACHO, indicate that a substantial fraction of the Galactic dark matter (DM) is in compact form, with a typical…
