H-alpha Velocity Fields of Normal Spiral Disks
David R. Andersen, M. A. Bershady, L. S. Sparke +4
We present H-alpha velocity fields for a sample of nearly face--on spiral galaxies observed with DensePak on the WIYN telescope. We combine kinematic inclinations and position angl…
Starbursts and the Evolution of Gas-Rich Galaxies
John S. Gallagher, Christopher J. Conselice, Lynn D. Matthews +1
Moderately luminous starbursts in the nearby universe often occur in disk galaxies that are at most subject to mild external perturbations. An investigation of this type of galaxy…
Patterns of Super Star Cluster Formation in `Clumpy' Starburst Galaxies
J. S. Gallagher, N. L. Homeier, C. J. Conselice +1
We present preliminary results from a Hubble Space Telescope (HST) WFPC2 investigation of spatial and temporal distributions of star clusters in the clumpy irregular galaxy NGC 767…
The Properties of Young Clusters in M82
L. J. Smith, J. S. Gallagher
We present a detailed study of two luminous super star clusters in the starburst galaxy M82. Spectra, covering 3250-8790 A at a resolution of 1.6 A, were obtained at the 4.2 m Will…
Physical morphology and triggers of starburst galaxies
C. J. Conselice, M. A. Bershady, J. S. Gallagher
We present a method of determining the likely triggering mechanisms for luminous, nearby starbursts based on their optical asymmetry and (B-V) color -- what we term as indices of `…
