Giant Elliptical Galaxies seen forming in the early Universe

Dusty Galaxies From Early Universe In Throes Of Intense Burst Of Star
Formation
"For many years it has been thought that these giant elliptical galaxies
formed most of their stars at very early times in the Universe, within
the first billion years after the Big Bang. However, very few examples
of these very distant and very bright dusty sources have been found in
submillimetre surveys, until the LESS collaboration completed their
survey of a Full Moon-sized patch of sky in the southern hemisphere
constellation of Fornax. Their survey is the largest and deepest of its
kind in submillimetre radiation and reveals over a hundred galaxies that
are forming stars at a prodigious rate.

Working with their new map, the team identified one of the submillimetre
sources as being associated with a star forming galaxy which is seen
just 1 billion years after the Big Bang. This remarkable galaxy shows
the signatures of both intense star formation and obscured black hole
growth when the Universe was only 10 percent of its current age. Dr.
Coppin and the LESS team suggest that there could be far more
submillimetre galaxies lurking at these early times than had previously
been thought. Dr Coppin comments, “The discovery of a larger number of
such active galaxies at such an early time would be at odds with current
galaxy formation models”."

Cool. Is this a new instrument that has come online?

You mean the APEX telescope in the Atacama Desert of Chile? I don't know
how new it is, but it should be relatively new. New enough that I think
they blew it up in the Quantum of Solace James Bond movie. :-)

Bond is really hard on telescopes.
