UDFj-39546284 is a high-redshift Lyman-break galaxy discovered by the Hubble Space Telescope in infrared Hubble Ultra-Deep Field (HUDF) observations in 2009.
Hubble finds a new contender for galaxy distance record
2011年1月26日 · The dim object, called UDFj-39546284, is likely to be a compact galaxy of blue stars that existed 480 million years after the Big Bang, only four percent of the Universe’s current age. It is tiny. Over one hundred such mini-galaxies would be needed to …

Astronomers have used Hubble to spot what they think is the furthest and one of the very earliest galaxies ever seen in the Universe. Candidate galaxy UDFj-39546284 appears as a faint red blob in this ultra deep field exposure taken with the NASA/ESA Hubble Space Telescope.
Distant Galaxy Is Record Breaker | Science | AAAS
2011年1月26日 · Bouwen's co-author Marijn Franx of Leiden Observatory adds that UDFj-39546284 is just a candidate galaxy as long as its distance has not been confirmed by direct spectroscopic measurements of the object's redshift. In principle, it could be an extremely red mini-galaxy much closer to Earth.

2011年1月26日 · These images zoom into the Hubble telescope's HUDF WFC3/IR image around the galaxy UDFj-39546284, which scientists say is 13.2 billion years old - the oldest, farthest galaxy yet discovered.
PHOTOMETRIC CONSTRAINTS ON THE REDSHIFT OF z ∼ 10 CANDIDATE UDFj ...
2013年2月15日 · The sharp break in the SED of UDFj-39546284 and blue spectral slope redward of the break is suggestive of a z ∼ 10–12 galaxy. The best-fit photometric redshift for UDFj-39546284 using all the data, including the deep IRAC and K s-band constraints, is z = 11.8 ± 0.3.
