Interests
- Current Projects
- Sundry contributions to the Keck CMB polarization experiment to be
sent to the South Pole late 2010. Direct descendant of the BICEP
experiment, sister to BICEP-II (the eldest), and SPIDER (the youngest).
- POLAR-1, a prototype South Pole CMB polarization telescope, aimed at
mapping the lensing contribution to the B-mode CMB polariation.
- SISP - Stanford Imaging Spectropolarimeter: an optical transition-edge
sensor, photon counting, spectrally sensitive polarimeter. An upgreade
of OpTES, the instrument developed by Prof. Blas Cabrera's group
in collaboration with Prof. Roger Romani, who provides the astronomical
motivation with pulsars and other rapidly variable, compact targets.
- QUIET (Q/U Imaging Experiment) ,
a new cosmic microwave background telescope project that replaced
CBI in Chile.
The Church group at Stanford have been responsible for the telescope.
See Pictures at an
Integration at Caltech where we integrated the telescope,
deck, and Q-band receiver in Spring of 2008.
- Upgrades at the Stanford Student Observatory
- Recent Projects
- Measuring the Sunyaev-Zeldovich effect with SuZIE-II ("Sunyaev-Zeldovich
Infrared Experiment", though "infrared" is a stretch).
See
http://www.stanford.edu/~schurch/suzie.html
- Building the next generation SZ instrument:
SuZIE-III.
At right is a picture of the cryostat under construction.
July 2006: first observing run.
See also Sarah's
page.
- Optical and mechanical assistance with QUaD ( QUEST on DASI),
a CMB polarization experiement now deployed at the South Pole.
- Stanford Cluster Search
Realistically, this project has ended, though there is still one
more candidate, with a redshift estimated at 1.0 or greater, to be
confirmed.
- High redshift QSO properties
- Other Instrumentation
- see first light images from
Ingrid
the infrared camera for William Herschel Telescope that I worked
on while at RGO, taken over by
Chris Packham and the team at La Palma in the Canary Islands.
(or just see M100 which I
pinched from Chris' web site.)
- Optical imaging spectroscopy: new design concept, hopefully
to be implemented soon in hardware. Goal: galaxy cluster
velocity distribution in one observation.
