We present results from two radio and two optical SETI programs
at the University of California, Berkeley:
The SERENDIP IV sky survey searches for narrow band radio signals at the 305 meter Arecibo Observatory in Puerto Rico. The program uses a 168 million channel spectrum analyzer, running in "piggyback" mode, using a dedicated receiver to take data 24 hours a day, year round.
Berkeley's most recent SETI project is SETI@home, which uses desktop computers of over a million volunteers to analyze 40 Terabytes of data from Arecibo Observatory. SETI@home is the largest supercomputer on the planet, currently averaging 20 Teraflops.
The SEVENDIP optical search searches for ns timescale pulses at visible wavelengths. The target list includes nearby F, G, K and M stars, plus a few globular cluster and galaxies. The pulse search utilizes Berkeley's 30 inch automated telescope at Leuschner Observatory.
The other Berkeley optical SETI program searches for narrow band coherent
signals in high resolution stellar spectra taken by Marcy and his colleagues as
part of their on-going search for planets at Lick, Keck, and the
SETI, spectrum analyzer, distributed computing, pulse detector.
Principal Author Biography
Dan Werthimer is director of the SERENDIP SETI program and chief
scientist of SETI@home at the University of California, Berkeley. He was
associate professor in the engineering and physics departments of San Francisco
State University and has been a visiting professor at Beijing Normal University,
the University of St. Charles in Marseille, Eotvos University in Budapest, and
taught at universities in Peru, Egypt, Ghana, Ethiopia, Zimbabwe, Uganda and
Kenya. Werthimer has published numerous scientific papers in the
fields of SETI, radio astronomy, instrumentation and science education, and is
editor of the book "Astronomical and Biochemical Origins and the Search for
Life in the Universe".
