Shell Galaxies, Dynamical Friction, and Dwarf Disruption
Ivana Ebrova, Bruno Jungwiert, Gabriela Canalizo +2
Using N-body simulations of shell galaxies created in nearly radial minor mergers, we investigate the error of collision dating, resulting from the neglect of dynamical friction an…
Shell Galaxies: Dynamical Friction, Gradual Satellite Decay and Merger Dating
Ivana Ebrova, Bruno Jungwiert, Gabriela Canalizo +2
With the goal to refine modelling of shell galaxies and the use of shells to probe the merger history, we develop a new method for implementing dynamical friction in test-particle…
Galaxy Zoo Green Peas: Discovery of A Class of Compact Extremely Star-Forming Galaxies
Carolin N. Cardamone, Kevin Schawinski, Marc Sarzi +14
We investigate a class of rapidly growing emission line galaxies, known as "Green Peas", first noted by volunteers in the Galaxy Zoo project because of their peculiar bright green…
Galaxy Zoo : 'Hanny's Voorwerp', a quasar light echo?
Chris Lintott, Kevin Schawinski, William Keel +17
We report the discovery of an unusual object near the spiral galaxy IC 2497, discovered by visual inspection of the Sloan Digital Sky Survey (SDSS) as part of the Galaxy Zoo projec…
Low-Energy Astrophysics: Stimulating the Reduction of Energy Consumption in the Next Decade
P. J. Marshall, N. Bennert, E. S. Rykoff +27
In this paper we address the consumption of energy by astronomers while performing their professional duties. Although we find that astronomy uses a negligible fraction of the US e…
A Search for H2O Megamasers in High-z Type-2 AGNs
Nicola Bennert, Richard Barvainis, Christian Henkel +1
We report a search for H2O megamasers in 274 SDSS type-2 AGNs (0.3 < z < 0.83), half of which can be classified as type-2 QSOs from their [OIII] 5007 luminosity, using the Robert C…
