PSETI Seminar Michael Garrett March 2, 2023 Abstract: I will present some of the SETI research results and teaching activities I have been leading at the University of Manchester, UK, over the last few years. In terms of research, the focus has been on four main activities: (i) placing new constraints on the prevalence of extraterrestrial transmitters in the Milky Way and beyond by taking into account both foreground and break ground stars/galaxies surveyed by the Breakthrough Listen programme (Wlodarczyk-Sroka set al. 2020, Garrett & Siemion 2022) (ii) recent progress in SETI follow-up observations using long-baseline interferometers (Wandia et al. 2023 submitted), (iii) simulations of Earth radio leakage associated with growing mobile communication systems (Saide et al. 2023) and (iv) searching for Kardashev Type III civilisations via extreme outliers in the radio-MIR correlation (Chen & Garrett 2021). With respect to teaching, we have been running an interdisciplinary, under-graduate course at Manchester: “Are We Alone ?” - The Search for Extraterrestrial Life. This attracts students from all faculties, covering a wide range of different astrophysical, biological, social and cultural topics associated with SETI.
