Identification of two bright z>3 submillimeter galaxy candidates in the COSMOS field

M. Aravena, J. D. Younger, G. G. Fazio +5

We present high-resolution interferometric Submillimeter Array (SMA) imaging at 890 microns (~2" resolution) of two millimeter selected galaxies -- MMJ100015+021549 and MMJ100047+0…

Mergers in Lambda-CDM: Uncertainties in Theoretical Predictions and Interpretations of the Merger Rate

Philip F. Hopkins, Darren Croton, Kevin Bundy +10

Different methodologies lead to order-of-magnitude variations in predicted galaxy merger rates. We examine and quantify the dominant uncertainties. Different halo merger rates and…

Deep, ultra-high-resolution radio imaging of submillimetre galaxies using Very Long Baseline Interferometry

A. D. Biggs, J. D. Younger, R. J. Ivison

We present continent-scale VLBI - obtained with the European VLBI Network (EVN) at a wavelength of 18cm - of six distant, luminous submm-selected galaxies (SMGs). Our images have a…

A physical model for the origin of the diffuse cosmic infrared background

Joshua D. Younger, Philip F. Hopkins

We present a physical model for origin of the cosmic diffuse infrared background (CDIRB). By utilizing the observed stellar mass function and its evolution as input to a semi-empir…

The physical scale of the far-infrared emission in the most luminous submillimetre galaxies II: evidence for merger-driven star formation

J. D. Younger, G. G. Fazio, M. L. N. Ashby +11

We present high-resolution 345 GHz interferometric observations of two extreme luminous (L_{IR}>10^{13} L_sun), submillimetre-selected galaxies (SMGs) in the COSMOS field with the…

Intense Star Formation within Resolved Compact Regions in a Galaxy at z=2.3

Mark Swinbank, Ian Smail, Steve Longmore +18

Massive galaxies in the early Universe have been shown to be forming stars at surprisingly high rates. Prominent examples are dust-obscured galaxies which are luminous when observe…
