CONCERTO at APEX: Installation and Technical Commissioning
We describe the deployment and first tests on sky of CONCERTO, a large field-of-view (18.6 arc-min) spectral-imaging instrument. The instrument operates in the range 130–310 GHz from the APEX 12-metres telesco...

Open AccessDetection of companion galaxies around hot dust-obscured hyper-luminous galaxy W0410-0913
The phase transition between galaxies and quasars is often identified with the rare population of hyper-luminous, hot dust-obscured galaxies. Galaxy formation models predict these systems to grow via mergers, ...

A massive core for a cluster of galaxies at a redshift of 4.3
Massive galaxy clusters have been found that date to times as early as three billion years after the Big Bang, containing stars that formed at even earlier epochs1–3. The high-redshift progenitors of these galaxy...

Galaxy growth in a massive halo in the first billion years of cosmic history
Two extremely massive galaxies are seen 800 million years after the Big Bang, showing the rapid growth of early structure and marking the most massive halo known in that era.

Dusty starburst galaxies in the early Universe as revealed by gravitational lensing
A spectroscopic redshift survey of extraordinarily bright millimetre-wave-selected sources of carbon monoxide line emission — originating from star-forming molecular gas — shows that at least ten of these sour...

Intense star formation within resolved compact regions in a galaxy at z = 2.3
The individual star-forming regions of the massive galaxies in the early Universe, at redshifts of around z = 2, are beyond the reach of even the largest of today's telescopes. But with help from gravitational le...
