A new method for classifying galaxy SEDs from multiwavelength photometry

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...

The colour distribution of galaxies at redshift five

Science

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...

Constraints on the star-formation rate of z ~ 3 LBGs with measured metallicity in the CANDELS GOODS-South field

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 ~...

The evolution of the dust temperatures of galaxies in the SFR-M* plane up to z ~ 2

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...

The bright end of the galaxy luminosity function at z~7: before the onset of mass quenching?

Science

We present the results of a new search for bright star-forming galaxies at redshift z ≃ 7 within the UltraVISTA second data release (DR2) and UKIDSS (UKIRT Infrared Deep Sky Survey) UDS (Ultra Deep Survey) DR10 data, which together provide 1.65 deg2 of near-infrared...
