Abstract Detail
14 January, 2006 - 2:35 PM ALMA as spectrometerA. Wootten (NRAO) The Atacama Large Millimeter Array is a
large international telescope project under construction in northern
Chile on a site at Chajnantor of 5 km elevation. The excellent
atmospheric transmission at that site in the millimeter and
sub-millimeter wavelength ranges will allow ALMA to provide detailed
images of the sources of the the Cosmic Microwave Background and the
Cosmic Far-Infrared Background radiation, near the wavelengths of the
two strongest peaks in the spectral energy distribution of the
Universe (ALMA will cover a broad total spectral wavelength range from
10mm to 0.3 mm or shorter wavelengths), For any given receiver on ALMA
within this wide band, 16 GHz of spectral information will be
processed. This capability gives ALMA sensitive capability for
measuring the redshifts of objects of uncertain distance, as well as
for serendipitous study of the physical conditions in galaxies owing
to the simultaneous measurement of other spectral line diagnostics. Download presentation
