Mass-to-Light versus Color Relations for Dwarf Irregular Galaxies
Kimberly A. Herrmann, Deidre A. Hunter, Hong-Xin Zhang +1
We have determined new relations between colors and mass-to-light ratios () for dwarf irregular (dIrr) galaxies, as well as for transformed . These…
Near-exponential surface densities as hydrostatic, nonequilibrium profiles in galaxy discs
Curtis Struck, Bruce G. Elmegreen
Apparent exponential surface density profiles are nearly universal in galaxy discs across Hubble types, over a wide mass range, and a diversity of gravitational potential forms. Se…
Ocular Shock Front in the Colliding Galaxy IC 2163
Michele Kaufman, Bruce G. Elmegreen, Curtis Struck +5
ALMA observations in the CO 1 - 0 line of the interacting galaxies IC 2163 and NGC 2207 at 2" x 1.5" resolution reveal how the encounter drives gas to pile up in narrow, ~ 1 kpc wi…
The properties, origin and evolution of stellar clusters in galaxy simulations and observations
C. L. Dobbs, A. Adamo, C. G. Few +16
We investigate the properties and evolution of star particles in two simulations of isolated spiral galaxies, and two galaxies from cosmological simulations. Unlike previous numeri…
Exponential Disks from Stellar Scattering: III. Stochastic Models
Bruce G. Elmegreen, Curtis Struck
Stellar scattering off irregularities in a galaxy disk has been shown to make an exponential radial profile, but no fundamental reason for this has been suggested. Here we show tha…
Long-Lived Spiral Structure for Galaxies with Intermediate Size Bulges
Kanak Saha, Bruce Elmegreen
Spiral structure in disk galaxies is modeled with nine collisionless N-body simulations including live disks, halos, and bulges with a range of masses. Two of these simulations mak…
