How to Reconcile the Observed Velocity Function of Galaxies with Theory
Alyson M. Brooks, Emmanouil Papastergis, Charlotte R. Christensen +4
Within a Lambda Cold Dark Matter (LCDM) scenario, we use high resolution cosmological simulations spanning over four orders of magnitude in galaxy mass to understand the deficit of…
Constraining the age of the NGC 4565 HI Disk Warp: Determining the Origin of Gas Warps
David J. Radburn-Smith, Roelof S. de Jong, David Streich +7
We have mapped the distribution of young and old stars in the gaseous HI warp of NGC 4565. We find a clear correlation of young stars (<600 Myr) with the warp, but no coincident ol…
Timescales on which Star Formation Affects the Neutral ISM
Adrienne M. Stilp, Julianne J. Dalcanton, Steven R. Warren +5
Turbulent neutral hydrogen (HI) line widths are often thought to be driven primarily by star formation (SF), but the timescale for converting SF energy to HI kinetic energy is uncl…
Drivers of HI Turbulence in Dwarf Galaxies
Adrienne M. Stilp, Julianne J. Dalcanton, Evan D. Skillman +3
Neutral hydrogen (HI) velocity dispersions are believed to be set by turbulence in the interstellar medium (ISM). Although turbulence is widely believed to be driven by star format…
Global HI Kinematics in Dwarf Galaxies
Adrienne M. Stilp, Julianne J. Dalcanton, Steven R. Warren +3
HI line widths are typically interpreted as a measure of ISM turbulence, which is potentially driven by star formation. In an effort to better understand the possible connections b…
The ACS Nearby Galaxy Survey Treasury IV. The Star Formation History of NGC 2976
Benjamin F. Williams, Julianne J. Dalcanton, Adrienne Stilp +8
We present resolved stellar photometry of NGC 2976 obtained with the Advanced Camera for Surveys (ACS) as part of the ACS Nearby Galaxy Survey Treasury (ANGST) program. The data co…
