Key Points
- A search for technosignatures was conducted around 11,680 stars using the Green Bank Telescope.
- The detections were confirmed to be of anthropogenic origin.
- The efficiency of the SETI pipeline used in the search was assessed.
- The selection of trial drift rates is important in accommodating line-of-sight accelerations.
- The study involved searching in the frequency range of 1.15-1.73 GHz, excluding a specific range.
- The efficiency of radio SETI pipelines is influenced by the drift rates of signals.
- The use of the Drake Figure of Merit (DFM) was discussed to assess search volume characteristics.
- The assumption of a uniform distribution of transmitters on the sky was mentioned as a disadvantage.

A search for technosignatures around 11,680 stars was conducted using the Green Bank Telescope at 1.15-1.73 GHz. The telescope was pointed in the directions of 62 TESS Objects of Interest, capturing radio emissions
This excerpt discusses a search for technosignatures, which are indicators of extraterrestrial technology, around 11,680 stars. The detections were inspected and confirmed to be of anthropogenic origin. The efficiency of the SETI pipeline used in the
In a search for technosignatures, the authors used the GAIA catalog to identify 11,680 known stars, with 8,091 having positive parallaxes. They observed these stars and their planetary systems with the GBT during four
The study focuses on the search for technosignatures around 11680 stars. The selection of trial drift rates is important in accommodating line-of-sight accelerations due to spins and orbits of exoplanets. The study can handle accelerations due
The study involved searching for technosignatures in the frequency range of 1.15-1.73 GHz, excluding the range of 1.20-1.34 GHz. The data used to estimate the efficiency of the search process was
The efficiency of radio SETI pipelines in detecting signals is influenced by the drift rates of the signals. Signals with higher drift rates have lower dechirping efficiency and are more challenging to recover. The performance of the pipeline decreases as the drift rate increases
The recovered signal-to-noise (S/N) values for a BL-like process imitating the Breakthrough Listen (BL) pipeline were lower than the injected values due to Doppler smearing. The UCLA SETI pipeline detected signals (MLc1
The text describes the use of the Drake Figure of Merit (DFM) to assess the search volume characteristics of surveys for technosignatures. The DFM measures the effectiveness of a search based on factors such as transmitter power, search area,
The authors discuss the search for technosignatures around 11,680 stars using the Green Bank Telescope (GBT) and Parkes Observatory. They mention the disadvantage of assuming a uniform distribution of transmitters on the sky, but note that this assumption
The efficiency of the BL-like process for detecting technosignatures is estimated to be 5.7% for certain drift rates, suggesting that previous estimates of search volumes and the number of transmitters need revisions. The UCLA SETI pipeline has a
This document provides characteristics of primary sources observed in 2020-2021 and 2022-2023 as part of a search for technosignatures around TESS exoplanets. The characteristics include the TESS Object of Interest (TO
This document contains a list of references to various papers and datasets related to the search for technosignatures. The references include studies conducted using the Green Bank Telescope to search for technosignatures in different planetary systems, such as those in the Kepler
