SETI follow-up observations
Student paper other, 10 credits / 15 HE creditsStudent thesis
The G-HAT team (G-HAT: Glimpsing Heat from Alien Technologies) compiled a catalogue of 93 galaxies that could host Kardashev-III civilizations [Griffith et al., 2015], using data from the WISE space telescope. Their method was based on the detection of the civilization's "waste heat": as any physical process takes place, heat is being released to the environment and it can be detected as an excess of the IR flux of the object. Garrett  combined the data from the G-HAT catalogue with the 20cm flux from the NRAO VLA Sky Survey (NVSS) and 9 objects with an anomalous flux excess at IR wavelengths were identied. This work is based on the the needed follow-up observations for each of those 9 sources.
This work is divided into three parts: in the first part we explain the theory of the "waste heat" search method, in the second part we give details about our submitted proposal for a submillimeter follow-up observation of NGC0814, using the Atacama Pathnder EXperiment (APEX) and in the third part we present a strategy for the required follow-up observations for the rest of the candidates.
