    Microlensing events of the LMC are better explained by stars within the LMC than by MACHOs
    The recently reported microlensing events of the Large Magellanic Cloud (LMC) have caused much excitement, and have been interpreted as due to 'dark objects'...

    Microlensing-based search for extragalactic MACHOs
    In this talk we first make a review on gravitational lensing and microlensing as an introduction, followed by a discussion on the most recent work of our group...

    Multiple stellar populations in Magellanic Cloud clusters - III. The first evidence of an extended main sequence turn-off in a young cluster: NGC 1856
    Recent studies have shown that the extended main-sequence turn-off (eMSTO) is a common feature of intermediate-age star clusters in the Magellanic Clouds (MCs)...

    Multiple stellar populations in Magellanic Cloud clusters - VI. A survey of multiple sequences and Be stars in young clusters
    The split main sequences (MSs) and extended MS turnoffs (eMSTOs) detected in a few young clusters have demonstrated that these stellar systems host multiple...

    Multiple stellar populations in Magellanic Cloud clusters – V. The split main sequence of the young cluster NGC 1866
    One of the most unexpected results in the field of stellar populations of the last few years is the discovery that some Magellanic Cloud globular clusters...

    Multiple stellar populations in Magellanic Cloud clusters. I. An ordinary feature for intermediate age globulars in the LMC?
    Context: The discovery of multiple main sequences (MS) in the massive clusters NGC 2808 and Omega Centauri, along with multiple subgiant branches in NGC 1851...

    Multiple stellar populations in Magellanic Cloud clusters. II. Evidence also in the young NGC 1844?
    We used Hubble Space Telescope observations to study the young cluster NGC 1844 in the Large Magellanic Cloud (LMC). We estimated the fraction and the mass...

    Multiplicity among the cool supergiants in the Magellanic Clouds
    The characterization of multiplicity of high-mass stars is of fundamental importance to understand their evolution, the diversity of observed core-collapse...

    Multiplicity of the red supergiant population in the young massive cluster NGC 330
    Context. The multiplicity properties of massive stars are one of the important outstanding issues in stellar evolution. Quantifying the binary statistics of all...
