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

Finding Distant Galaxies

A short movie showing how the observed spectrum of star-forming galaxies changes as we observe it at higher and higher redshift. Redshift is denoted here in this movie as "z". Note how the break in the spectrum shifts to redder and redder wavelengths as a result of this redshifting effect. To be able to identify galaxies at the highest redshifts (and thus near the beginning of the universe), it is necessary to be able to measure the fluxes of sources at near-infrared wavelengths (>1 micron). High-redshift galaxies are frequently found by noting a significant break in the spectrum as seen through a set of discrete filters.
