چکیده

We present the SCUBA Legacy Catalogues, two comprehensive sets of continuum maps (and catalogues) using data at 850 μm and 450 μm of the various astronomical objects obtained with the Submillimetre Common User Bolometer Array (SCUBA). The Fundamental Map Dataset contains data only where superior atmospheric opacity calibration data were available. The Extended Map Dataset is comprised of data regardless of the quality of the opacity calibration. Each Dataset contains 1.2 × 1.2 maps at locations where data existed in the JCMT archive, imaged using the matrix inversion method. The Fundamental Dataset is comprised of 1423 maps at 850 μm and 1357 maps at 450 μm. The Extended Dataset is comprised of 1547 maps at 850 μm. Neither Dataset includes high sensitivity, single chop SCUBA maps of “cosmological fields” nor solar system objects. Each Dataset was used to determine a respective Object Catalogue, consisting of objects identified within the respective 850 μm maps using an automated identification algorithm. The Fundamental and Extended Map Object Catalogues contain 5061 and 6118 objects respectively. Objects are named based on their respective J2000 position of peak 850 μm intensity. The Catalogues provide for each object the respective maximum 850 μm intensity, estimates of total 850 μm flux and size, and tentative identifications from the SIMBAD Database. Where possible, the Catalogues also provide for each object its maximum 450 μm intensity and total 450 μm flux, and flux ratios.

The Hubble Deep Field North SCUBA Super-map – I. Submillimetre maps, sources and number counts

We investigate the emission of submillimetre-wave radiation from galaxies in a 165 arcmin2 region surrounding the Hubble Deep Field North. The data were obtained from dedicated observing runs from our group and others using the SCUBA camera on the James Clerk Maxwell Telescope (JCMT), and combined using techniques specifically developed for low signal-to-noise ratio source recovery. The resulti...

SCUBA Observations of the Host Galaxies of Gamma-Ray Bursts

In recent years, a population of galaxies with huge infrared luminosities and dust masses has been discovered in the submillimetre. Observations suggest that the AGN contribution to the luminosities of these submillimetre-selected galaxies is low; instead their luminosities are thought to be mainly due to strong episodes of star formation following merger events. Our current understanding of GR...

Millimetre continuum observations of southern massive star formation regions . II . SCUBA observations of cold cores and the dust grain emissivity index ( β )

We report the results of a submillimetre continuum emission survey targeted toward 78 star formation regions, 72 of which are devoid of methanol maser and UC HII regions, identified in the SEST/SIMBA millimetre continuum survey of Hill et al. (2005). At least 45 per cent of the latter sources, dubbed ‘mm-only’, detected in this survey are also devoid of mid infrared MSX emission. The 450 and 85...

Testing the connection between the X - ray and submillimetre backgrounds using Chandra

The powerful combination of the Chandra X-ray telescope, the SCUBA submillimetre-wave camera and the gravitational lensing effect of the massive galaxy clusters A 2390 and A 1835 has been used to place stringent X-ray flux limits on six faint submillimetre SCUBA sources and deep submillimetre limits on three Chandra sources which lie in fields common to both instruments. One further source is m...

Fourier Transform Spectroscopy of the submillimetre continuum emission from hot molecular cores

We have used a Fourier Transform Spectrometer on the James Clerk Maxwell Telescope to study the submillimetre continuum emission from dust in three hot molecular cores (HMC). The spectral index β of the dust emission for these sources has been determined solely within the 30GHz wide 350GHz (850μm) passband to an accuracy comparable to those determined through multi-wavelength observations. We f...
