Welcome to Caltech Observational Cosmology!
Our group develops novel
instrumentation in order to study the birth and evolution of the universe. Here are the projects that we are currently involved in:
|
ACBAR
(Arcminute Cosmology Bolometer Array Receiver) ACBAR is currently imaging the CMB at multiple frequencies with 4' resolution from the Viper telescope at the South Pole.
|
|
BICEP
(Background Imaging of Cosmological Extragalactic Polarization) BICEP will map degree-scale CMB polarization from the South Pole.
|
|
Bolocam
A a large format, mm-wave camera used at the Caltech Sub-millimeter Observatory to achieve high mapping speed and 1' resolution.
|
|
Boomerang
The final flight of Boomerang is complete! In January of 2003, Boomerang flew
an exact prototype of the polarized 143 GHz Planck HFI focal plane, resulting in the first bolometric detection of CMB polarization. The first round of analyses of the B03 data are complete, papers and spectra have been made public 7/21/05.

|
Planck Surveyor HFI
We are responsible for building the bolometric detectors for the High Frequency Instrument on the Planck Surveyor. Planck will map the entire sky with 5' resolution in 2007/2008.

|
Spider
Spider is a balloon borne observatory designed to probe the epoch of Inflation
through measurements of the CMB polarization on
the largest angular scales. Large format planar arrays and
wide area sky coverage enable a definitive measurement of the signature of
inflationary gravitational waves in CMB.
