    Prevalence of endoparasites in stray and fostered dogs and cats in Northern Germany

    To get an overview of the current state of endoparasite prevalences in stray and not well-cared dogs and cats, faecal samples of 445 stray and foster dogs and 837 stray and foster cats were collected at their ...

    A Next Generation Microlensing Search: SuperMacho

    Past microlensing experiments such as the MACHO project have discovered the presence of a larger than expected number of microlensing events towards the Large Magellanic Cloud (LMC). These events could represe...

    Direct detection of a microlens in the Milky Way

    The nature of dark matter remains mysterious, with luminous material accounting for at most ∼25 per cent of the baryons in the Universe1,2. We accordingly undertook a survey looking for the microlensing of stars ...

    The MACHO Project 5.7 Year LMC Results

    The MACHO collaboration has analyzed 5.7years of photometry on approximately 11.7 million stars in the Large Magellanic Cloud (LMC) in a search for gravitational microlensing events. Two sets of cuts were used...

    Discovery of a planet orbiting a binary star system from gravitational microlensing

    The properties of the recently discovered1,2 extrasolar planets were not anticipated by theoretical work on the formation of planetary systems, most models for which were developed to explain our Solar System. In...

    Properties of LMC Planetary Nebulae and Parent Populations in the MACHO Database

    The MACHO microlensing experiment’s time-sampled photometry database contains blue and red lightcurves for nearly 9 million stars in the central bar region of the Large Magellanic Cloud (LMC). We have identifi...

    Bulge δ Scuti Stars in the Macho Database

    We describe the search for δ Scuti stars in the MACHO database of bulge fields. Concentrating on a sample of high amplitude δ Scutis, we examine the light curves and pulsation modes. We also discuss their spat...

    Statistical Issues in the MACHO Project

    The MACHO project is an ongoing survey project which collects photometric timeseries data on roughly 20 million stars in the LMC, SMC, and Galactic bulge. The data is irregularly time sampled, largely due to w...
