    Antitruncation of Disks in Early-Type Barred Galaxies
    The disks of spiral galaxies are commonly thought to be truncated: the radial surface brightness profile steepens sharply beyond a certain radius (3-5 inner...

    Are C60 Molecules Detectable in Circumstellar Shells of R Coronae Borealis Stars?
    The hydrogen-poor, helium-rich, and carbon-rich character of the gas around R Coronae Borealis (RCB) stars has been suggested to be a site for formation of C60...

    Are Fossil Groups Early-forming Galaxy Systems?
    Using the Illustris cosmological simulation, we investigate the origin of fossil groups in the {M}200={10}13{--}{10}13.5 {M}⊙ {h}-1 mass regime. We examine the...
