Sampled over l range of 160-170 or .25-1.15 degrees

Mount includes rotation of aperture plane along line of sight

Slide 15

WMAP

Wilkinson Microwave Anisotropy Probe

Launched 2001 to map CMB radiation with higher resolution, sensitivity, and accuracy than COBE

MAXIMA

http://cosmology.berkeley.edu/group/cmb/image/maxima_map.gif

Millimeter Anisotropy eXperiment Imaging Array

angular power spectrum with a unique set of "acoustic peaks" between the angular scales of 2 degrees and 10'

can provide precise estimates of cosmological constants

Slide 17

Plank

Part of the first European mission to study the “birth” of the Universe

Construction to be finished in 2005

Launched in the same rocket with Herschel in 2007

Will observe the Cosmic Microwave Background (left over radiation from the Big Bang)

Slide 19

The South Pole Telescope (SPT)

An 8-meter precision submillimeter-wave telescope

Distant galaxy clusters through detection of their Sunyaev-Zel’dovich effect (SZE)

Dark Energy will be observed in great detail

1,000 Bolometers (heat detectors) measure the temperature differences up to 10 millionths of a degree

Mapping large areas of the sky will be very beneficial to modern astronomers

Slide 21

The Very Small Array (VSA)

Will be built as an Inferometer, due to the changing weather patterns and the basic noise of the instruments that are experienced

Uses radio signals received by each antenna

Construction finished in 1999 now in Tenerife
