Evolution of star formation in the UKIDSS Ultra Deep Survey Field - II : Star formation as a function of stellar mass between z=1.46 and z=0.63
(2015-12-01)
We present new results on the evolution of the cosmic star formation rate as a function of stellar mass in the SXDS-UDS field. We make use of narrow-band selected emission line galaxies in four redshift slices between z = ...
Cold dust emission from X-ray AGN in the SCUBA-2 Cosmology Legacy Survey : dependence on luminosity, obscuration & AGN activity
(2015-11-21)
We study the 850um emission in X-ray selected AGN in the 2 sq-deg COSMOS field using new data from the SCUBA-2 Cosmology Legacy Survey. We find 19 850um bright X-ray AGN in a high-sensitivity region covering 0.89 sq-deg ...
Deriving star formation histories from photometry using energy balance spectral energy distribution modelling
(2015-10-21)
Panchromatic spectral energy distribution (SED) fitting is a critical tool for determining the physical properties of distant galaxies, such as their stellar mass and star formation rate. One widely used method is the ...
H-ATLAS/GAMA : Quantifying the morphological evolution of the galaxy population using cosmic calorimetry
(2015-10-01)
Using results from the Herschel Astrophysical Terrahertz Large-Area Survey and the Galaxy and Mass Assembly project, we show that, for galaxy masses above approximately 1.0e8 solar masses, 51% of the stellar mass-density ...
Molecular and atomic gas in dust lane early-type galaxies - I : Low star-formation efficiencies in minor merger remnants
(2015-06-01)
In this work we present IRAM-30m telescope observations of a sample of bulge-dominated galaxies with large dust lanes, which have had a recent minor merger. We find these galaxies are very gas rich, with H2 masses between ...
