Testing the clump model of SiO maser emission
M. D. Gray, R. J. Ivison, E. M. L. Humphreys +1
Building on the detection of J=7-6 SiO maser emission in both the v=1 and v=2 vibrational states towards the symbiotic Mira, R Aquarii, we have used the James Clerk Maxwell Telesco…
A hyperluminous galaxy at z = 2.8 found in a deep submillimetre survey
Rob Ivison, Ian Smail, J. -F. Le Borgne +5
We present a detailed study of SMM 02399-0136, a hyperluminous, active galaxy selected from a sub-mm survey of the distant Universe. This galaxy is the brightest source in the fiel…
Observational limits to source confusion in the millimetre/submillimetre waveband
A W Blain, R J Ivison, Ian Smail
The first observations to detect a population of distant galaxies directly in the submillimetre waveband have recently been made using the new Submillimetre Common-User Bolometer A…
The simultaneous detection of 22- and 321-GHz H2O maser emission towards the symbiotic Mira R Aquarii
Rob Ivison, J. A. Yates, P. J. Hall
We report high spatial and spectral resolution measurements of masers towards R Aqr and H1-36, both of which are examples of the sub-class of symbiotic stars that contain a long-pe…
No C+ emission from the z=3.137 damped Lyman-alpha absorber towards PC1643+4631A
Rob Ivison, A. P. Harrison, I. M. Coulson
We describe a search for redshifted [C II] in a z=3.137 damped Ly-alpha absorption system that has a large neutral hydrogen column density and which was controversially reported to…
Dust in high-z radio-loud AGN
Andrea Cimatti, Wolfram Freudling, Huub Roettgering +2
We present continuum observations of a small sample of high-redshift, radio-loud AGN (radio galaxies and quasars) aimed at the detection of thermal emission from dust. Seven AGN we…
