Submillimetre source counts: first results from SCUBA
The SCUBA submillimetre camera has opened up new possibilities for tracing the evolution of active star formation in dusty galaxies to high redshift, with profound implications for our understanding of the star formation history of the Universe and the contribution from galaxies to the anisotropy of the microwave sky. We review results from several submillimetre surveys started during SCUBA’s f...
متن کاملSCUBA Deep Fields and Source Confusion
Deep submillimetre(submm)-wave surveys made over the last three years using the SCUBA camera at the 15-m James Clerk Maxwell Telescope (JCMT) have revealed a new population of very luminous high-redshift galaxies. The properties of this population, and their contribution to the intensity of the extragalactic background radiation field are described briefly, especially in the context of the SCUB...
متن کاملAn 850μm SCUBA map of the Groth Strip and reliable source extraction
We present an 850μm map and list of candidate sources in a sub-area of the Groth Strip observed using SCUBA. The map consists of a long strip of adjoining jigglemaps covering the southwestern 70 arcmin of the original WFPC2 Groth Strip to an average 1 σ rms noise level of ≃ 3.5mJy. We initially detect 7 candidate sources with signal-to-noise ratios (SNRs) between 3.0 and 3.5 σ and 4 candidate s...
متن کاملObservational limits to source confusion in the millimetre/submillimetre waveband
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 Array (SCUBA) on the James Clerk Maxwell Telescope (JCMT). The results indicate that a large number of distant galaxies are radiating strongly in this waveband. Here we discuss their significance for source confusion i...
متن کاملThe SCUBA Legacy Catalogues: Submillimetre Continuum Objects Detected by SCUBA
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 r...
