These images were created from Hubble data from proposals 12060 (PI: S. Faber, University of California, Santa Cruz) and 12099 (PI: A. Riess (STScI/JHU). The lead author on the paper is S. Rodney (JHU).
This image is a composite of separate exposures acquired by the WFC3 and ACS instruments on HST. Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
