Metallicity Gradients and Gas Flows in Galaxy Pairs
Lisa J. Kewley, David Rupke, H. Jabran Zahid +2
We present the first systematic investigation into the metallicity gradients in galaxy close pairs. We determine the metallicity gradients for 8 galaxies in close pairs using HII r…
A Galactic Center Origin for HE 0437-5439, the Hypervelocity Star near the Large Magellanic Cloud
Warren R. Brown, Jay Anderson, Oleg Y. Gnedin +4
We use Hubble Space Telescope imaging to measure the absolute proper motion of the hypervelocity star (HVS) HE 0437-5439, a short-lived B star located in the direction of the Large…
Empirical optical k-Corrections for redshifts <= 0.7
Eduard Westra, Margaret J. Geller, Michael J. Kurtz +2
The Smithsonian Hectospec Lensing Survey (SHELS) is a magnitude limited spectroscopically complete survey for R<=21.0 covering 4 square degrees. SHELS provides a large sample (15,5…
The Mass Profile of the Galaxy to 80 kpc
Oleg Y. Gnedin, Warren R. Brown, Margaret J. Geller +1
The Hypervelocity Star survey presents the currently largest sample of radial velocity measurements of halo stars out to 80 kpc. We apply spherical Jeans modeling to these data in…
Triggered Star Formation in Galaxy Pairs at z=0.08-0.38
Deborah Freedman Woods, Margaret J. Geller, Michael J. Kurtz +3
We measure the strength, frequency, and timescale of tidally triggered star formation at redshift z=0.08-0.38 in a spectroscopically complete sample of galaxy pairs drawn from the…
Comparison of Hectospec Virial Masses with SZE Measurements
Kenneth Rines, Margaret J. Geller, Antonaldo Diaferio
We present the first comparison of virial masses of galaxy clusters with their Sunyaev-Zel'dovich Effect (SZE) signals. We study 15 clusters from the Hectospec Cluster Survey (HeCS…
