BLIPSS — Breakthrough Listen Investigation for Periodic Spectral Signals — Cornell University + SETI Institute + breakthrough-listen collaboration. Lead akshay-suresh (Cornell graduate student), advisor vishal-gajjar.

Search design

  • Telescope: Green Bank Telescope (GBT).
  • Band: 4–8 GHz.
  • Target: Galactic Center — dense stellar population maximizes line-of-sight count of potentially habitable systems and is a strategic beacon site for a galaxy-spanning civilization.
  • Signal class: periodic spectral signals — trains of narrowband pulses (sub-FM-channel bandwidth, periodic temporal structure). Distinct from pulsars (broadband) and from classical continuous-wave (CW) narrowband SETI.
  • Validation: algorithm recovers known pulsars with expected periodicities before being applied to production GBT scans.

Output

  • Paper: Suresh et al., “A 4–8 GHz Galactic Center Search for Periodic Technosignatures,” accepted Astronomical Journal.
