    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...

    Are Gas-rich Ultra-diffuse Galaxies and Field Dwarfs Distinct?
    We explore the differences in gas-rich field ultra-diffuse galaxies (UDGs) and diffuse classical dwarf galaxies using an extensive atomic gas (H I) follow-up...
