Compass and Scale Image for 'El Gordo'
El Gordo, ACT-CL J0102-4915
9.7 billion light-years (3 billion parsecs)
The Hubble data are from proposal 12755: J. Hughes (Rutgers University), F. Menanteau (Rutgers University/University of Illinois, Urbana-Champaign), L. Infante and L.F. Barrientos (Ponticia Universidad Catolica de Chile), and R. Mandelbaum (Carnegie Mellon University), and archival data from proposal 12477: F. High (University of Chicago) et al.
F606W ((V), F625W (r), F775W (i), F814W (I), and F850LP (z)
This composite image includes exposures acquired by the ACS instruments on the Hubble Space Telescope. 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:
Blue: F625W (r)
Green: F775W (i)
Red: F850LP (z)
Cyan: Derived Mass
