A Submillimetre Imaging Polarimeter at the James Clerk Maxwell Telescope
A polarimeter has been built for use with the Submillimetre Common-User Bolometer Array (SCUBA), on the James Clerk Maxwell Telescope (JCMT) in Hawaii. SCUBA is the first of a new generation of highly sensitive submillimetre cameras, and the UK/Japan Polarimeter adds a polarimetric imaging/photometry capability in the wavelength range 350 to 2000 μm. Early science results range from measuring t...
متن کاملThe JCMT Nearby Galaxies Legacy Survey V : The CO ( J = 3 - 2 ) Distribution and Molecular Outflow in NGC 4631
We have made the first map of CO(J=3-2) emission covering the disk of the edge-on galaxy, NGC 4631, which is known for its spectacular gaseous halo. The strongest emission, which we model with a Gaussian ring, occurs within a radius of 5 kpc. Weaker disk emission is detected out to radii of 12 kpc, the most extensive molecular component yet seen in this galaxy. From comparisons with infrared da...
متن کاملNon - Circular Motions in Disk Galaxies : Application to Ngc 2976
We present a new procedure to fit non-axisymmetric flow patterns to 2-D velocity maps of spiral galaxies. We concentrate on flows caused by bar-like or oval distortions to the total potential that may arise either from a non-axially symmetric halo or a bar in the luminous disk. We apply our method to high-quality CO and Hα data for the nearby, low-mass spiral NGC 2976 previously obtained by Sim...
متن کاملThe Fluid Dynamics of James Clerk Maxwell
We tend to think of Maxwell’s genius entirely in relation to his creation of electromagnetic theory (as summarised by Maxwell’s equations) on the one hand, and to his seminal development of the kinetic theory of gases (leading to the Maxwell-Boltzmann distribution, the derivation of transport coefficients like viscosity and thermal diffusivity for gases and associated validation of the continuu...
متن کاملTowards the automated reduction and calibration of SCUBA data from the James Clerk Maxwell Telescope
The Submillimetre Common User Bolometer Array (SCUBA) instrument has been operating on the James Clerk Maxwell Telescope (JCMT) since 1997. The data archive is now sufficiently large that it can be used to investigate instrumental properties and the variability of astronomical sources. This paper describes the automated calibration and reduction scheme used to process the archive data with part...
