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…
Research Science and Education: The NSF's Astronomy and Astrophysics Postdoctoral Fellowship
Dara Norman, Marcel Agueros, Timothy M. Brown +29
The NSF's Astronomy and Astrophysics Postdoctoral Fellowship (AAPF) is exceptional among the available postdoctoral awards in Astronomy and Astrophysics. The fellowship is one of t…
The environmental dependence of neutral hydrogen content in spiral galaxies
Jesse Miner, Jim Rose, Sheila Kannappan
We present a study of the relationship between the deficiency of neutral hydrogen and the local three-dimensional number density of spiral galaxies in the Arecibo catalog of global…
Systematic Uncertainties in Stellar Mass Estimation for Distinct Galaxy Populations
Sheila J. Kannappan, Eric Gawiser
We show that different stellar-mass estimation methods yield overall mass scales that disagree by factors up to ~2 for the z=0 galaxy population, and more importantly, relative mas…
SN 2005cg: Explosion Physics and Circumstellar Interaction of a Normal Type Ia Supernova in a Low-Luminosity Host
Robert Quimby, Peter Hoeflich, Sheila J. Kannappan +5
We present the spectral evolution, light curve, and corresponding interpretation for the "normal-bright" Type Ia Supernova 2005cg discovered by ROTSE-IIIc. The host is a low-lumino…
