Projects
Research at the observatory spans many fields of radio astronomy. This research is performed by the staff at the observatory in conjunction with professors, postdoctoral researchers and graduate students from various institutions. As a university-operated observatory, graduate student research with the instruments at Owens Valley has been extensive—setting the observatory apart from national radio astronomy facilities. Long-term commitments of observing time have been available to students enabling more innovative and comprehensive projects than would have been possible at a national observatory. Typically 5-7 graduate students are supported with fellowships and have done a significant fraction of their Ph.D. research with the observatory instruments. Projects have ranged from purely observational research with the existing instrumentation to the design, development, and use of new instrumentation.
OVRO-LWA
The Owens Valley Long Wavelength Array is a low frequency (15-85 MHz) all-sky imaging and beam-forming array with focus on the auroral radio emission from exoplanets, prompt counterparts to gravitational wave events, extended airshowers produced by cosmic-rays and the 21-cm power spectrum in the Cosmic Dawn epoch.
DSA
The Deep Synoptic Array is a 110-dish array that will localize hundreds of fast radio bursts (FRBs) to their host galaxies. The DSA will enable transformational advances in our understanding of the origins of FRBs, and of the unseen baryons in the CGM and IGM. An expanded version of this project with 2000 antennas…

40-meter
In 2007, the 40-m Telescope embarked on a new research campaign. In support of the Fermi Gamma-ray Space Telescope, launched in 2008, the OVRO 40-m Telescope is monitoring more than 1800 blazars about twice per week.
COMAP
COMAP is an intensity mapping experiment using carbon monoxide (CO) lines to trace the distribution of star-forming galaxies in the Epoch of Galaxy Assembly and the Epoch of Reionization. Ancillary science includes line and continuum surveys of regions of the Galaxy and studies of the anomalous microwave emission (AME).
SPRITE
The Stokes Polarimetric Radio Interferometer for Time-domain Experiments will use 5 of the 10m CARMA antennas. Will observe different types of transient objects 1mm/3mm full polarization and wide bandwidth. Currently seeking funding.
EHT
The Event Horizon Telescope is an international collaboration that links radio dishes across the globe to create an Earth-sized interferometer. It has been used to measure the size of the emission regions of the two supermassive black holes with the largest apparent event horizons: SgrA* at the center of the Milky Way and M87 in the center of the Virgo A galaxy.
