    Everything that glitters is not gold: V1315 Cas is not a dormant black hole
    The quest for quiet or dormant black holes has been ongoing since several decades. Ellipsoidal variables possibly indicate the existence of a very high-mass...

    Evidence for a 20pc Disk at the Nucleus of Centaurus A
    We report Hubble Space Telescope NICMOS observations of the central region of NGC 5128 at 2.2 mu m and in Pa alpha . The continuum images show extended emission...

    Evidence for a black hole in the historical X-ray transient A 1524-61 (= KY TrA)
    We present Very Large Telescope spectroscopy, high-resolution imaging, and time-resolved photometry of KY TrA, the optical counterpart to the X-ray binary A...

    Evidence for a black hole in the X-ray transient XTE J1859+226
    We present the results of time-resolved optical photometry and spectroscopy of the X-ray transient XTE J1859+226 (V406 Vul). Photometric observations taken...

    Evidence for a compact jet dominating the broad-band spectrum of the black hole accretor XTE J1550-564
    The black hole X-ray binary XTE J1550-564 was monitored extensively at X-ray, optical and infrared wavelengths throughout its outburst in 2000. We show that it...

    Evidence for a deficit of young and old stars in the Milky Way inner in-plane disc
    We give independent proof of the deficit of stars in the in-plane central disc (2

    Evidence for a fundamental stellar upper mass limit from clustered star formation
    The observed masses of the most massive stars do not surpass about 150 Msolar. This may either be a fundamental upper mass limit which is defined by the physics...
