Measuring Galaxy Velocity Dispersions with Hectospec
Daniel Fabricant, Igor Chilingarian, Ho Seong Hwang +2
We describe a robust technique based on the ULySS IDL code for measuring velocity dispersions of galaxies observed with the MMT's fiber-fed spectrograph, Hectospec. This procedure…
Reducing Systematic Error in Cluster Scale Weak Lensing
Yousuke Utsumi, Satoshi Miyazaki, Margaret J. Geller +5
Weak lensing provides an important route toward collecting samples of clusters of galaxies selected by mass. Subtle systematic errors in image reduction can compromise the power of…
The Chemical Evolution of Star-Forming Galaxies Over the Last 11 Billion Years
H. Jabran Zahid, Margaret Geller, Lisa Kewley +3
We calculate the stellar mass-metallicity relation at five epochs ranging to z~2.3. We quantify evolution in the shape of the mass-metallicity relation as a function of redshift; t…
