SETI's blind spot: Technological Acceleration and fleeting technosignatures
Michael A. Garrett
The search for extraterrestrial intelligence (SETI) has traditionally framed the detection challenge with a focus on the parameter in the Drake equation - the communicative lif…
Searching for Extraterrestrial Intelligence with the SKA
Chenoa D. Tremblay, Alex Andersson, Joe Bright +19
The search for technosignatures (also known as the Search for Extraterrestrial Intelligence or SETI) depends critically on our ability to distinguish artificial signals from the ri…
Radio Activity from the Rapidly Rotating T dwarf 2MASS 2228-4310
Kelvin Wandia, Michael A. Garrett, Aaron Golden +7
We present the detection of 2MASS J22282889-4310262 (2M2228), a T6/T6.5 brown dwarf, using the Karl G. Jansky Very Large Array (VLA) archival data observed at C band (4-8 GHz) over…
Upper Limits on Radio Emission from the K2-18 System
Kelvin Wandia, Chenoa Tremblay, Michael A. Garrett +11
Stellar and planetary magnetic fields play a crucial role in the habitability of a planet and the integrity of its atmosphere. The recently claimed detection of biosignatures, meth…
Simulating the Stellar Bycatch: Constraining the Prevalence of Extraterrestrial Transmitters within Radio SETI Surveys
Louisa A. Mason, Michael A. Garrett, Andrew P. V. Siemion
Searches for radio technosignatures place constraints on the prevalence of extraterrestrial transmitters in our Galaxy and beyond. It is important to account for the complete stell…
Radio Emission from a Nearby M dwarf Binary
Kelvin Wandia, Michael A. Garrett, Robert J. Beswick +7
We present the detection of the binary system 2MASS J02132062+3648506 AB using the Karl G. Jansky Very Large Array (VLA) archive data observed at 4-8 GHz. The system is a triple co…
