Connecting Transitions in Galaxy Properties to Refueling
Sheila J. Kannappan, David V. Stark, Kathleen D. Eckert +12
We relate transitions in galaxy structure and gas content to refueling, here defined to include both the external gas accretion and the internal gas processing needed to renew rese…
The Fueling Diagram: Linking Galaxy Molecular-to-Atomic Gas Ratios to Interactions and Accretion
David V. Stark, Sheila J. Kannappan, Lisa H. Wei +4
To assess how external factors such as local interactions and fresh gas accretion influence the global ISM of galaxies, we analyze the relationship between recent enhancements of c…
The Distance to the Massive Galactic Cluster Westerlund 2 from a Spectroscopic and HST Photometric Study
Carlos A. Vargas Alvarez, Henry A. Kobulnicky, David R. Bradley +4
We present a spectroscopic and photometric determination of the distance to the young Galactic open cluster Westerlund 2 using WFPC2 imaging from the Hubble Space Telescope and gro…
