The XDF Paper

The XDF team has published a paper titled "The HST eXtreme Deep Field XDF: Combining all ACS and WFC3/IR Data on the HUDF Region into the Deepest Field Ever" discussing the methods used to produce the XDF dataset.

The paper can be downloaded from ADS or arXiv.org


The XDF Data Release v1.0

The XDF team has release the XDF v1.0 data products on the MAST HST data archive. These data include all optical and infrared data taken by Hubble covering the original Hubble Ultra-Deep Field (HUDF) program.

The data can be downloaded from the MAST High Level Science Products page XDF Data Release 1.0

  • Hubble Goes to the eXtreme to Assemble Farthest Ever View of the Universe
  • NASA - Hubble Science
  • Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field.

  • Hubble's Deepest View of Universe Unveils Never-Before-Seen Galaxies
  • Hubble Site - NewsCenter
  • NASA's Hubble Space Telescope has made the deepest image of the universe ever taken in near-infrared light. The faintest and reddest objects in the image are galaxies that formed 600 million years after the Big Bang. No galaxies have been seen before at such early times. The new deep view, taken in late August 2009, also provides insights into how galaxies grew in their formative years early in the universe's history.
