The Calibration of Mid-Infrared Star Formation Rate Indicators
D. Calzetti, R. C. Kennicutt, C. W. Engelbracht +25
With the goal of investigating the degree to which the mid-infrared emission traces the star formation rate (SFR), we analyze Spitzer 8 um and 24 um data of star-forming regions in…

We present imaging data and photometry for the COSMOS survey in 15 photometric bands between 0.3um and 2.4um. These include data taken on the Subaru 8.3m telescope, the KPNO and CT…
The effects of environment on morphological evolution between 0<z<1.2 in the COSMOS Survey
P. L. Capak, R. G. Abraham, R. S. Ellis +4
We explore the evolution of the morphology density relation using the COSMOS-ACS survey and previous cluster studies. The Gini parameter measured in a Petrosian aperture is found t…
