This page features mock observations for HST and JWST from supercomputer simulations, roughly the same size as the Hubble Ultra Deep Field region, or individual fields of more recent UDF-style campaigns (like the XDF, HUDF09/12, and the Frontier Fields). You can use your mouse cursor to zoom into individual regions and check out the simulated galaxy populations. Data is from the HST Ultra Deep Field (XDF release). Models are from the Illustris Project and Moving Mesh Cosmology project. Appears to work best in Firefox.

The above figure is derived from Figure 1bc of Vogelsberger et al. 2014, Nature, 509, 177–182 (08 May 2014; doi:10.1038/nature13316). HST Data were obtained from the Mikulski Archive for Space Telescopes (MAST). STScI is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555. Support for MAST for non-HST data is provided by the NASA Office of Space Science via grant NNX13AC07G and by other grants and contracts.



For now, just an example, in roughly R, Z, J bands (HST ACS/F435W, ACS/F850LP, WFC3/F160W). Works okay in Firefox, but seems to have trouble with scrolling in Chrome or Safari.



Same field, in roughly F115W, F200W, F356W filters for JWST's NIRCAM. Nearby universe has been subtracted.
