An ALMA survey of sub-millimetre Galaxies in the Extended Chandra Deep Field South: the far-infrared properties of SMGs (2013)
Journal Article

We exploit Atacama Large Millimeter Array (ALMA) 870 μm observations of sub-millimetre sources in the Extended Chandra Deep Field South to investigate the far-infrared properties of high-redshift sub-millimetre galaxies (SMGs). Using the precisely lo... Read More about An ALMA survey of sub-millimetre Galaxies in the Extended Chandra Deep Field South: the far-infrared properties of SMGs.

13CO and C18O emission from a dense gas disc at z = 2.3: abundance variations, cosmic rays and the initial conditions for star formation (2013)
Journal Article

We analyse the spectral line energy distributions of 13CO and C18O for the J = 1→0 up to J = 7→6 transitions in the gravitationally lensed ultraluminous infrared galaxy SMM J2135−0102 at z = 2.3. This is the first detection of 13CO and C18O in a high...

An ALMA Survey of Submillimeter Galaxies in the Extended Chandra Deep Field-South: The AGN Fraction and X-Ray Properties of Submillimeter Galaxies (2013)
Journal Article

The large gas and dust reservoirs of submillimeter galaxies (SMGs) could potentially provide ample fuel to trigger an active galactic nucleus (AGN), but previous studies of the AGN fraction in SMGs have been controversial largely due to the inhomogen...

An extended Herschel drop-out source in the center of AS1063: a normal dusty galaxy at z = 6.1 or SZ substructures? (2013)
Journal Article

In the course of our 870 μm APEX/LABOCA follow-up of the Herschel Lensing Survey we have detected a source in AS1063 (RXC J2248.7-4431) that has no counterparts in any of the Herschel PACS/SPIRE bands, it is a Herschel “drop-out” with S870/S500 ≥ 0.5...

On the evolution and environmental dependence of the star formation rate versus stellar mass relation since z ˜ 2 (2013)
Journal Article

This paper discusses the evolution of the correlation between galaxy star formation rates (SFRs) and stellar mass (M*) over the last ∼10 Gyr, particularly focusing on its environmental dependence. We first present the mid-infrared (MIR) properties of... Read More about On the evolution and environmental dependence of the star formation rate versus stellar mass relation since z ˜ 2.

The SCUBA-2 cosmology legacy survey : blank-field number counts of 450-μm-selected galaxies and their contribution to the cosmic infrared background (2013)
Journal Article

The first deep blank-field 450 μm map (1σ ≈ 1.3 mJy) from the Submillimetre Common-User Bolometer Array-2 SCUBA-2 Cosmology Legacy Survey (S2CLS), conducted with the James Clerk Maxwell Telescope (JCMT) is presented. Our map covers 140 arcmin2 of the...

An ALMA survey of submillimetre galaxies in the Extended Chandra Deep Field South : high-resolution 870 μm source counts (2013)
Journal Article

We report the first counts of faint submillimetre galaxies (SMGs) in the 870-μm band derived from arcsecond-resolution observations with the Atacama Large Millimeter Array (ALMA). We have used ALMA to map a sample of 122 870-μm-selected submillimetre...

An ALMA survey of submillimeter galaxies in the Extended Chandra Deep Field South : source catalog and multiplicity (2013)
Journal Article

We present an Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 0 survey of 126 submillimeter sources from the LABOCA ECDFS Submillimeter Survey (LESS). Our 870 μm survey with ALMA (ALESS) has produced maps ~3× deeper and with a beam area ~20...

Mapping the clumpy structures within submillimeter galaxies using laser-guide star adaptive optics spectroscopy (2013)
Journal Article

We present the first integral-field spectroscopic observations of high-redshift submillimeter-selected galaxies (SMGs) using Laser-Guide Star Adaptive Optics. We target Hα emission of three SMGs at redshifts z ~ 1.4-2.4 with the OH-Suppressing Infrar...

Dust-obscured star formation in the outskirts of XMMU J2235.3-2557, a massive galaxy cluster at z = 1.4 (2013)
Journal Article

Star formation (SF) in the galaxy populations of local massive clusters is reduced with respect to field galaxies, and tends to be suppressed in the core region. Indications of a reversal of the SF–density relation have been observed in a few z > 1.4...
