The Genesis of the Milky Way's Thick Disk via Stellar Migration
Sarah R. Loebman, Rok Roskar, Victor P. Debattista +3
The separation of the Milky Way disk into a thin and thick component is supported by differences in the spatial, kinematic and metallicity distributions of their stars. These diffe…
Misaligned Angular Momentum in Hydrodynamic Cosmological Simulations: Warps, Outer Discs, and Thick Discs
Rok Roškar, Victor P. Debattista, Alyson M. Brooks +5
We present a detailed analysis of a disc galaxy forming in a high-resolution fully cosmological simulation to investigate the nature of the outer regions of discs and their relevan…
IFU Spectroscopy of the Stellar Disk Truncation Region of NGC 6155
Peter Yoachim, Rok Roškar, Victor P. Debattista
Like the majority of spiral galaxies, NGC 6155 exhibits an exponential surface brightness profile that steepens significantly at large radii. Using the VIRUS-P IFU spectrograph, we…
The NGC 404 Nucleus: Star Cluster and Possible Intermediate Mass Black Hole
Anil C. Seth, Michele Cappellari, Nadine Neumayer +8
We examine the nuclear morphology, kinematics, and stellar populations in nearby S0 galaxy NGC 404 using a combination of adaptive optics assisted near-IR integral-field spectrosco…
Long-lived double-barred galaxies in N-body simulations
Juntai Shen, Victor Debattista
Many barred galaxies harbor small-scale secondary bars in the center. The evolution of such double-barred galaxies is still not well understood, partly because of a lack of realist…
The ACS Nearby Galaxy Survey Treasury V. Radial Star Formation History of NGC 300
Stephanie M. Gogarten, Julianne J. Dalcanton, Benjamin F. Williams +13
We present new Hubble Space Telescope (HST) observations of NGC 300 taken as part of the ACS Nearby Galaxy Survey Treasury (ANGST). Individual stars are resolved in these images do…
