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 Relationship Between Molecular Gas and Star Formation in Low-Mass E/S0 Galaxies
Lisa H. Wei, Stuart N. Vogel, Sheila J. Kannappan +3
We consider the relationship between molecular-gas and star-formation surface densities in 19 morphologically defined E/S0s with stellar mass <~ 4x10^10 M_sun, paying particular at…
Gas Mass Fractions and Star Formation in Blue-Sequence E/S0 Galaxies
L. H. Wei, S. J. Kannappan, S. N. Vogel +1
Recent work has identified a population of low-redshift E/S0 galaxies that lie on the blue sequence in color vs. stellar mass parameter space, where spiral galaxies typically resid…
Extended Light in E/S0 Galaxies and Implications for Disk Rebirth
Amanda J. Moffett, Sheila J. Kannappan, Seppo Laine +3
The recent discovery of extended ultraviolet (XUV) disks around a large fraction of late-type galaxies provides evidence for unexpectedly large-scale disk building at recent epochs…
Cold Gas in Blue-Sequence E/S0s: Galaxies in Transition
Lisa H. Wei, Sheila J. Kannappan, Stuart N. Vogel +1
We examine the HI+H_2 content of blue-sequence E/S0s -- a recently identified population of galaxies that are morphologically early type, but reside alongside spiral galaxies in co…
