"... In case this would hold, an extragalactic origin would
seem unlikely, as high (random) DMs would be added by
intergalactic dust. A more likely option could be a galactic
source producing quantized chirped signals, but this
seems most surprising. If both of these options could be
excluded, only an artificial source (human or non-human)
must be considered, particularly since most bursts have
been observed in only one location (Parkes radio telescope).
A re-assessment of man-made phenomena, such
as perytons (Burke-Spolaor et al. 2011), would then
be required. Failing some observational bias, the suggestive
correlation with terrestrial time standards seems
to nearly clinch the case for human association of these
peculiar phenomena.
In the end we only claim interesting features which
further data will verify or refute. ..."
