Searching for broadband pulsed beacons from 1883 stars using neural networks

Vishal Gajjar, Dominic LeDuc, Jiani Chen +19

The search for extraterrestrial intelligence at radio frequencies has largely been focused on continuous-wave narrowband signals. We demonstrate that broadband pulsed beacons are e…

Re-Analysis of Breakthrough Listen Observations of FRB 121102: Polarization Properties of Eight New Spectrally Narrow Bursts

Jakob T. Faber, Vishal Gajjar, Andrew P. V. Siemion +15

We report polarization properties for eight narrowband bursts from FRB 121102 that have been re-detected in a high-frequency (4-8 GHz) Breakthrough Listen observation with the Gree…

Lens Flare: Magnified X-Ray Binaries as Passive Beacons in SETI

Brian C. Lacki

Low mass X-ray binaries (LMXBs) containing neutron stars are both extremely luminous and compact, emitting up to ~10^6 L_sun within a kilometer-scale boundary layer. This combinati…

SETI at Planck Energy: When Particle Physicists Become Cosmic Engineers

Brian C. Lacki

What is the meaning of the Fermi Paradox -- are we alone or is starfaring rare? Can general relativity be united with quantum mechanics? The searches for answers to these questions…
