Abstract [en]

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 [2015] 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.
