The Breakthrough Listen Initiative : Overview Milky Way Galactic Plane 1 Million Nearby Stars 100 Galaxies Survey Commitment : 10 years, 100 million dollars. 1 day of Breakthrough Listen = 1 year of any previous search All data accessible to the scientific community and the public.

“A SILICON - VALLEY APPROACH TO THE S EARCH FOR A DVANCED L IFE ”

The Breakthrough Listen Initiative : Telescopes Automated Planet Finder - Lick Observatory PS Howard Isaacson (UC Berkeley) • Search for extremely narrow emission lines from artificial lasers • Extremely high resolution “ Levy Spectrometer ” • 374 - 950 nm, λ / Δλ = 10 5 • 10% Green Bank Telescope - Green Bank, WV PS Emilio Enriquez (UC Berkeley / Radboud) • Radio search focusing on targeted and raster observations • Nearly continuous frequency coverage 300 MHz - 100 GHz • Flexible IF system can deliver up to 10 GHz dual-pol analog bandwidth • Extremely radio quiet (Federally protected radio quiet zone) • ~20% Parkes Telescope - New South Wales, Australia PS Daniel Price (UC Berkeley / Swinburne) • Radio search focusing on surveys • Southern hemisphere location gives great access to galactic plane • Multi-beam receiver allows very efficient L-band (1.2 - 1.5 GHz) galactic plane surveys (Parkes Multibeam Receiver) • Wide-band single-pixel and Phased Array Feed upgrades possible. • ~20%

The Breakthrough Listen Initiative : Telescopes Automated Planet Finder - Lick Observatory PS Howard Isaacson (UC Berkeley) Green Bank Telescope - Green Bank, WV PS Emilio Enriquez (UC Berkeley / Radboud) • 12 GHz baseband data recorder (450 Gbps) • 8 PB Storage • 65x GPUs (high resolution spectroscopy ++ ) Parkes Telescope - New South Wales, Australia PS Daniel Price (UC Berkeley / Swinburne) • 5 GHz Baseband Data Recorder (190 Gbps) • 3.3 PB Storage • 28x GPUs (high resolution spectroscopy ++ )

10 - 100 GHz : Completely unexplored part of the radio spectrum, a singular capability of GBT. Nearby Stars, Nearby Galaxies, Galactic Center Multi-beam surveys of Galactic Plane and Galactic Center. Nearby star and galaxy observations with new ultra- wide-band feed (Oct 2018) Additional observations of nearby stars to probe intermittency, cores of nearby galaxies.

10 GHz + Radio SETI • Greatly diminished ISM impairments (Cordes and Lazio, Messerschmitt et al.) • Cost effectiveness of beacons (Benford et al.) • Channel capacity and information (Morrison et al)

10 + GHz Radio SETI • Extragalactic “ free-space ” microwave window? Brian Lacki 2018
