    A Correlation between Galaxy Light Concentration and Supermassive Black Hole Mass
    We present evidence for a strong correlation between the concentration of bulges and the mass of their central supermassive black hole (Mbh)-more concentrated...

    A Detection of Sgr A* in the Far Infrared
    We report the first detection of the Galactic Center massive black hole, Sgr A*, at 100 μm and 160 μm. Our measurements were obtained with PACS on board the...

    A late jet rebrightening revealed from multiwavelength monitoring of the black hole candidate XTE J1752-223
    We present optical monitoring of the black hole candidate XTE J1752-223 during its 2009-10 outburst and decay to quiescence. The optical light curve can be...

    A long-term optical-X-ray correlation in 4U 1957+11
    Three years of optical monitoring of the low-mass X-ray binary (LMXB) 4U 1957+11 is presented. The source was observed in V, R and i bands using the Faulkes...

    A lower limit to the accretion disc radius in the low-luminosity AGNNGC 1052 derived from high-angular resolution data
    We investigate the central sub-arcsec region of the low-luminosity active galactic nucleusNGC 1052, using a high-angular resolution data set that covers 10...

    A refined sub-grid model for black hole accretion and AGN feedback in large cosmological simulations
    In large-scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion on to black holes and AGN feedback are commonly used. Such...

    A TiO study of the black hole binary GRO J0422+32 in a very low state
    We present 53 simultaneous photometric (I band) and spectroscopic (6900-9500Å) observations of GRO J0422+32, taken during 1997 December. From these we determine...
