• Bulges Of Nearby Galaxies With Spitzer: The Growth Of Pseudobulges In Disk Galaxies And Its Connection To Outer Disks 

    Fisher, David B.; Drory, Niv; Fabricius, Maximillian H. (2009-05)
    We study star formation rates (SFRs) and stellar masses in bulges of nearby disk galaxies. For this we construct a new SFR indicator that linearly combines data from the Spitzer Space Telescope and the Galaxy Evolution ...
  • The Central Dark Matter Distribution Of NGC 2976 

    Adams, Joshua J.; Gebhardt, Karl; Blanc, Guillermo A.; Fabricius, Maximillian H.; Hill, Gary J.; Murphy, Jeremy D.; van den Bosch, Remco C. E.; van de Ven, Glenn (2012-01)
    We study the mass distribution in the late-type dwarf galaxy NGC 2976 through stellar kinematics obtained with the Visible Integral Field ReplicableUnit Spectrograph Prototype and anisotropic Jeans models as a test of ...
  • Dwarf Galaxy Dark Matter Density Profiles Inferred From Stellar And Gas Kinematics 

    Adams, Joshua J.; Simon, Joshua D.; Fabricius, Maximillian H.; van den Bosch, Remco C. E.; Barentine, John C.; Bender, Ralf; Gebhardt, Karl; Hill, Gary J.; Murphy, Jeremy D.; Swaters, R. A.; Thomas, Jens; van de Ven, Glenn (2014-07)
    We present new constraints on the density profiles of dark matter (DM) halos in seven nearby dwarf galaxies from measurements of their integrated stellar light and gas kinematics. The gas kinematics of low-mass galaxies ...
  • Measuring Dark Matter Profiles Non-Parametrically In Dwarf Spheroidals: An Application To Draco 

    Jardel, John R.; Gebhardt, Karl; Fabricius, Maximillian H.; Drory, Niv; Williams, M. J. (2013-02)
    We introduce a novel implementation of orbit-based (or Schwarzschild) modeling that allows dark matter density profiles to be calculated non-parametrically in nearby galaxies. Our models require no assumptions to be made ...
