CANDELS Dwarf Galaxies

The CANDELS team identified 69 dwarf galaxies that are undergoing intense bursts of star formation. The dwarf galaxies were found in two regions of the sky called the Great Observatories Deep Survey-South and the UKIDSS Ultra Deep Survey (part of the UKIRT Infrared Deep Sky Survey). Each dwarf is shown centered in cutouts made from near-infrared (I, J, and H band) images acquired by Hubble's Wide Field Camera 3 and Advanced Camera for Surveys. The light from these galaxies has been traveling for about 9 billion years. Many of the stars in nearby dwarf galaxies may have formed in similar starbursts around the same time. The background shows a wider near-infrared view of the CANDELS Ultra Deep Survey field.

About the data

GOODS South Deep (top) The image was created from Hubble WFC3 data from proposal 11359 , R. O'Connell (University of Virginia) and collaborators, combined with Hubble ACS GOODS v2.0 data, which includes data from proposal 9425 : M. Giavalisco (University of Massachusetts) et al., and proposal 10340 : A. Riess (JHU and STScI). The science team for this release is led by A. van der Wel (Max Planck Institute for Astronomy, Heidelberg, Germany), and the images were produced by A. Koekemoer (STScI).

Ultra Deep Survey (bottom) This image was created from HST data from proposal 12064 : S. Faber (University of California, Santa Cruz), et al. The science team for this release is led by A. van der Wel (Max Planck Institute for Astronomy, Heidelberg, Germany), and the images were produced by A. Koekemoer (STScI).
