Submillimetre Detection of the z=2.83 Lyman-Break Galaxy, Westphal-MM8, and Implications for SCUBA2
(2009-03-12)
We present confusion limited submillimetre (submm) observations with the SCUBA camera on the JCMT of the z=2.83 Lyman-break galaxy (LBG), Westphal-MM8, reaching an 850um sensitivity even greater than that achieved in the ...
Understanding the nature of the optically faint radio sources and their connection to the submillimeter population
(2002-05-10)
We present a sample of 43 submillimeter sources detected (at >3 sigma), drawn from our program to follow-up optically faint radio sources with SCUBA. These sources already have associated radio and in many cases optical ...
Constraining Star Formation and AGN in z~2 Massive Galaxies using High Resolution MERLIN Radio Observations
(2009-05-21)
We present high spatial resolution MERLIN 1.4GHz radio observations of two high redshift (z~2) sources, RGJ123623 (HDF147) and RGJ123617 (HDF130), selected as the brightest radio sources from a sample of submillimetre-faint ...
Adaptive optics near-IR imaging of NGC2992 - unveiling core structures related to radio figure-8 loops
(2000-05-11)
We present near-IR adaptive optics, VLA radio and HST optical imaging of the nearby Seyfert galaxy NGC2992. Spiral structure and an extension to the West are traced down to the core region at the limiting resolution of our ...
Near-IR adaptive optics imaging of nuclear spiral structure in the Seyfert galaxy, NGC3227
(2002-04-04)
We present high spatial resolution, near-IR images in J, H, K of the nucleus of NGC3227, obtained with the Adaptive Optics bonnette on CFHT. The ~0.15 arcsec (17pc) resolution allows structures to be probed in the core ...
An upper limit to [C II] emission in a z ~= 5 galaxy
(2005-05-01)
Low-ionization-state far-infrared (FIR) emission lines may be useful diagnostics of star-formation activity in young galaxies, and at high redshift may be detectable from the ground. In practice, however, very little is ...
Restframe Optical Spectroscopic Classifications for Submillimeter Galaxies
(2006-11-10)
We report the results of a systematic near-infrared spectroscopic survey using the Subaru, VLT and Keck Telescopes of a sample of high redshift Ultra-luminous Infrared Galaxies (ULIRGs) mainly composed of submillimeter-selected ...
Submillimetre and far-infrared spectral energy distributions of galaxies: the luminosity-temperature relation and consequences for photometric redshifts
(2003-01)
The spectral energy distributions (SEDs) of dusty high-redshift galaxies are poorly sampled in frequency and spatially unresolved. Their form is crucially important for estimating the large luminosities of these galaxies ...
SCUBA observations of Hawaii 167
(2000-11)
We present the first submillimetre observations of the z=2.36 broad absorption line system Hawaii 167. Our observations confirm the hypothesis that Hawaii 167 contains a massive quantity of dust, the optical depth of which ...
