Using the UltraVISTA catalogs, we investigate the evolution in the 11.4 Gyr since z=3 of the progenitors of local ultra-massive galaxies (log(Mstar/M⊙)≈11.8; UMGs), providing a complete and consistent picture of how the most massive galaxies at z=0 have assembled. By...

We report the detection at 850 microns of the central source in SSA22-LAB1, the archetypal “Lyman-alpha Blob” (LAB), a 100 kpc scale radio-quiet emission-line nebula at z = 3.1. The flux density of the source, S 850 = 4.6 ± 1.1 mJy, implies the presence of...
Science
Method We present a new method to classify the broad-band optical–near-infrared spectral energy distributions (SEDs) of galaxies using three shape parameters (super-colours) based on a principal component analysis of model SEDs. As well as providing a compact...

We present the results of a study investigating the rest-frame ultraviolet (UV) spectral slopes of redshift z ≈ 5 Lyman-break galaxies (LBGs). By combining deep Hubble Space Telescope imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey and...
Science
The main aim of this work is to constrain the assembly history of high-redshift galaxies and the reliability of UV-based estimates of their physical parameters from an accurate analysis of a unique sample of z ~ 3 Lyman-break galaxies (LBGs). We analyse 14 LBGs at z ~...
Science
We study the evolution of the dust temperature of galaxies in the SFR- M* plane up to z ~ 2 using far-infrared and sub-millimetre observations from the Herschel Space Observatory taken as part of the PACS Evolutionary Probe (PEP) and Herschel Multi-tiered...
