    The multiple routes of galaxy transformation across the cosmic epochs
    In the local universe most of the stellar mass is in passive galaxies, where star formation isabsent or at very low levels. Understanding what are the...

    The nature of gamma-ray binaries
    The improvement on the Imaging Air Cherenkov Technique led to the discovery of a new class of compact binaries: the gamma-ray binaries. This small class consist...

    The NIR counterpart to XTE J1747-274(=IGR J17473-2721)
    We report follow-up observations confirming the near-infrared (NIR) counterpart to the X-ray transient XTE J1747-274/IGR J17473-2721 (ATEL #467, #498). A Ks=16...

    The omnipresent flux-dependent optical dips of the black hole transient Swift J1357.2−0933
    Swift J1357.2-0933 is a black hole transient that is of particular interest due to the optical recurrent dips found during its first two outbursts (in 2011 and...

    The Optical Counterpart to XTE J1817-330.
    We report the counterpart to the X-ray transient and black hole candidate XTE J1817-330 (ATEL #714). Our observations consist of a series of 5s and 10s g'-band...

    The orbital period, black hole mass, and distance to the X-ray transient GRS 1716-249 ( =N Oph 93)
    We present evidence for a 0.278(8) d ( =6.7 h) orbital period in the X-ray transient GRS 1716-249 (=N Oph 93), based on a superhump modulation detected during...

    The quest for axions
    We introduce the strong CP problem and the existence of the Axion as a possible solution. We discuss the possibility that axions are the dark matter of the...
