Deep multi-frequency radio imaging in the Lockman Hole using the GMRT and VLA: II. The spectral index of submillimetre galaxies
Edo Ibar, R. J. Ivison, P. N. Best +4
We have employed the GMRT and the VLA to map the Lockman Hole. At 610 and 1,400 MHz, we reach noise levels of 15 and 6 uJy/beam, respectively, with well-matched resolutions (~5").…
BLAST: the far-infrared/radio correlation in distant galaxies
R. J. Ivison, David M. Alexander, Andy D. Biggs +32
We investigate the correlation between far-infrared (FIR) and radio luminosities in distant galaxies, a lynchpin of modern astronomy. We use data from the Balloon-borne Large Apert…
AzTEC Half Square Degree Survey of the SHADES Fields -- I. Maps, Catalogues, and Source Counts
J. E. Austermann, J. S. Dunlop, T. A. Perera +45
We present the first results from the largest deep extragalactic millimetre-wavelength survey undertaken to date. These results are derived from maps covering over 0.7 deg^2, made…
Deep multi-frequency radio imaging in the Lockman Hole using the GMRT and VLA: I. The nature of the sub-mJy radio population
Edo Ibar, R. J. Ivison, A. D. Biggs +3
We describe multi-frequency data designed to probe the emission mechanism that dominates in faint radio sources. Our analysis is based on observations of the Lockman Hole using the…
A submillimetre galaxy at z=4.76 in the LABOCA survey of the Extended Chandra Deep Field South
Kristen Coppin, Ian Smail, David M. Alexander +30
We report on the identification of the highest redshift submm-selected source currently known: LESSJ033229.4-275619. This source was detected in the Large Apex BOlometer CAmera (LA…
