Three band submillimetre mapping of the Lagoon Nebula

Tothill, N. F. H. and White, Glenn J. (2000). Three band submillimetre mapping of the Lagoon Nebula. In: Imaging at Radio through Submillimeter Wavelengths ASP Conference Proceedings, Vol. 217, 06-09 Dec 1999, Tucson.



The Lagoon Nebula, M8, has been mapped at 450 μm, 850 μm, and 1.3 mm, using SCUBA and the IRAM 30-m telescope. The large-scale maps (~20' × 10') show clumpy structures surrounding the H II region, extending as far as M8E. The core sizes are around 15" - 30" (0.1 - 0.3 pc), with temperatures of 10 - 40 K. The mass spectrum of the cores is derived, together with estimates of the likely errors. The problems of measuring cores in regions of high-mass star formation are noted.
