Exponential galaxy discs as the quasi-stationary distribution in a Markov chain model simulating stellar scattering
Jian Wu, Curtis Struck, Bruce G. Elmegreen +1
Previous models have shown that stochastic scattering of stars in a two-dimensional galaxy disc can generate a time-independent surface density distribution that is an exponential…
Diverse Molecular Structures Across The Whole Star-Forming Disk of M83: High fidelity Imaging at 40pc Resolution
Jin Koda, Akihiko Hirota, Fumi Egusa +23
We present high-fidelity CO(1-0) imaging of molecular gas across the full star-forming disk of M83, using ALMA's 12m, 7m, and TP arrays and the MIRIAD package. The data have a mass…
Orbits and action changes during star-clump encounters responsible for the origin of exponential discs in dwarf galaxies
Jian Wu, Curtis Struck, Bruce G. Elmegreen +1
Previous studies found that stellar scattering by massive clumps can lead to the formation of exponential profiles in galaxy discs, but details on how a star is moved around have n…
The Dense Gas Mass Fraction and the Relationship to Star Formation in M51
Mark Heyer, Benjamin Gregg, Daniela Calzetti +15
Observations of 12CO J=1-0 and HCN J=1-0 emission from NGC 5194 (M51) made with the 50~meter Large Millimeter Telescope and the SEQUOIA focal plane array are presented. Using the H…
A Search for correlations between turbulence and star formation in THINGS galaxies
Bruce G. Elmegreen, Zorayda Martinez, Deidre A. Hunter
The spatial range for feedback from star formation varies from molecular cloud disruption on parsec scales to supershells and disk blowout on kiloparsec scales. The relative amount…
The Environments of CO Cores and Star Formation in the Dwarf Irregular Galaxy WLM
Haylee N. Archer, Deidre A. Hunter, Bruce G. Elmegreen +5
The low metallicities of dwarf irregular galaxies (dIrr) greatly influence the formation and structure of molecular clouds. These clouds, which consist primarily of H, are typi…
