The COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) survey will use the LRIS spectrograph on Keck-I to observe the Lyman-alpha forest of neutral hydrogen absorption in closely-spaced quasars and galaxies. This will allow us to create an unprecedented map of the cosmic web …
The nature of Dark Energy is one of the greatest mysteries in science today. It was discovered in 1998, when scientists found that the expansion of the universe is accelerating. We call the force driving this expansion Dark Energy, but beyond that we know very little. The Large Synoptic Survey Telescope (LSST) will produce a unique dataset of billions of galaxies, which will allow us to measure how Dark Energy behaves over time with unprecedented precision. The LSST dataset will also enable us to tackle several other questions in cosmology and fundamental physics.
The LSST Dark Energy Science Collaboration (LSST DESC) will prepare for and carry out a variety of cosmological analyses with the LSST survey. In advance of LSST's first observations, DESC will help prepare for LSST science analysis, make synergistic connections with ongoing cosmological surveys and provide the dark energy community with state of the art analysis tools.
The CARMA EDGE survey will provide a measurement of the distribution of molecular gas in a statistically significant sample of over one hundred galaxies. The survey targets the J = 1-0 transition of CO and its 13CO isotopologue, which trace the bulk of the cold, star-forming gas. Paired with matched IFU mapping of the entire optical spectrum, this survey enables studies of resolved star formation efficiencies and histories, gas and stellar kinematics, nebular extinctions, and ionized gas properties across the Hubble sequence. The EDGE survey is designed to move the field of millimeter-wave interferometry from the piecemeal collection of case studies into the realm of large samples.
The Panchromatic Hubble Andromeda Treasury (PHAT) used the Hubble Space Telescope (HST) to take pictures of our neighboring galaxy Andromeda, which is 2.5 million light years away from us. The exquisite spatial resolution of the HST resolved Andromeda into individual stars, meaning that we are able to study it at the same level of detail as our own Milky Way.
The Automated Planet Finder (APF) is a robotic 2.4-meter optical telescope stationed at Lick Observatory designed to assist with the search for extrasolar planets. The APF operates by targeting preprogrammed stars and observing them nightly over the course of several months in efforts to detect stellar motion and locate habitable planets.
NExSS is a cross-divisional initiative from NASA to create a research coordination network (RCN) with an emphasis on studying extrasolar planets and the potential for habitability. An RCN is a virtual structure to support groups of investigators to communication and coordinate research and educational activity. At Berkeley our contributions are the observations of extrasolar planets via direct imaging, the transit technique, and Doppler spectroscopy, plus the theoretical study of planet formation and subsequent evolution.

The Breakthrough Listen Initiative, funded by the Breakthrough Prize Foundation, is the most powerful, comprehensive and intensive scientific search ever undertaken for signs of intelligent life beyond Earth. The project is using the Green Bank radio telescope in West Virginia and the Parkes Telescope in Australia to search for radio transmissions from advanced civilizations. In addition, the Automated Planet Finder at Lick Observatory is being used to search for optical laser transmissions from other technological civilizations.
OPAL is the Outer Planet Atmospheres Legacy program. For the remainer of Hubble's lifetime, OPAL images the giant planets every year to study their dynamics, weather, and climate.
The Gemini Planet Imager (GPI) is a new science instrument that exploits the latest generation of adaptive optics technology, coronagraphy and detectors. We have successfully commissioned GPI at the Gemini South telescope in Chile and in 2014 we started a three year science program called GPIES (GPI Exoplanet Survey) that will survey 600 stars for the presence of young giant planets.
