SCUBA observations of Hawaii 167
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 is sufficient to completely extinguish our ultraviolet view of a central, buried quasar. Hawaii 167’s submillimetre luminosity and associated dust mass are similar to the ult...
متن کاملSCUBA observations of MAMBO sources
We have observed 23 sources from the MAMBO 1200μm survey with SCUBA at 850μm, detecting 19 of the sources. The sources generally have low values for the ratio of 850μm to 1200μm flux. Two possible explanations for the low values are either that the sources are at very high redshifts or that the global properties of the dust in the MAMBO sources are different from the global properties of dust i...
متن کاملSCUBA Observations of NGC 1275
Deep SCUBA observations of NGC 1275 at 450μm and 850μm along with the application of deconvolution algorithms have permitted us to separate the strong core emission in this galaxy from the fainter extended emission around it. The core has a steep spectral index and is likely due primarily to the AGN. The faint emission has a positive spectral index and is clearly due to extended dust in a patch...
متن کاملSCUBA observations of NGC 6946 ⋆
We present sub-millimetre images of the spiral galaxy NGC 6946 at 450 and 850 µm. The observations have been carried out using the scan/map imaging mode of the Sub-millimetre Common User Bolometer Array (SCUBA) at the James Clark Maxwell Telescope (JCMT). The comparison with a 12 CO(2-1) line emission map from IRAM and with an U-band image, clearly shows that the 850 µm emission is associated w...
متن کاملImplications of SCUBA observations for the Planck Surveyor
We investigate the implications for the Planck Surveyor of the recent sub-millimetre number counts obtained using the SCUBA camera. Since it observes at the same frequency as one of the higher frequency science channels on Planck, SCUBA can provide constraints on the point-source contribution to the CMB angular power spectrum, which require no extrapolation in frequency. We have calculated the ...
