    Gemini South Traces the Flow of Gas into the Grasp of the Black Hole in NGC 1097
    An international team led by Kambiz Fathi of the Rochester Institute of Technology (RIT) and Thaisa Storchi-Bergmann of the Instituto de Fisica in Porto Alegre, Brazil recently mapped the gas velocity field and structure within the circumnuclear ring of the SBb LINER/Seyfert 1 galaxy NGC 1097 in unprecedented detail. Using the Gemini Multi-object Spectrograph (GMOS) integral field unit (IFU) on Gemini South, in conjunction with HST/ACS observations, the team found clear evidence of radial streaming motions associated with spiral structures that extend to within ~10 parsecs (~33 lightyears) of the unresolved (<3.5 parsecs (<11.4 lightyears)) nucleus. These motions have been interpreted as evidence that a large-scale ''fueling chain'' transports gas from the outer regions of the galaxy's nucleus directly into the nuclear starburst and supermassive black hole. ...

    Gemini South Tracks Optical Microflares Around Black Hole in Binary System
    Binary stars evolve in interesting ways. The more massive star in a pair evolves faster and may explode as a supernova if its original mass is greater than about 7 times the mass of our Sun. The result is that either a neutron star or a black hole is found orbiting the lower-mass companion star - as is the case with A0620-00. This system consists of an X-ray novae star, powered by the sporadic accretion material from its companion, a K5 main-sequence star....
