these folks went looking for a signal, and found it. Hidden in noise, it is a simple beacon, but you have to use a Fourier transform to pick it out.
The really strange thing is that is only found in the same spectral class stars as our sun.
To the authors, this suggests a beacon for contact.
To me, this suggests a targeting light, a probe wavefront that marks a system as biologically active, and marked for destruction by a machine culture. There is location info in the database, so it could be modeled, to see if it looks like a bootstrap wave, and would be curious if there is a string of supernovas behind it.
Since most of the found signals are in halo stars, it is more likely an invasion from another galaxy, then a local population.
Signals probably from Extraterrestrial Intelligence. Analysis of 2.5 million SDSS spectra found signals predicted in a previous publication in only 234 stars overwhelmingly in the F2 to K1 spectral range
And there are weird things happening in galactic clusters too. As i posted in the open thread, a super dense cluster is the only way to stop a hypervelocity attack on a home base whether a planetary or Dyson structure. You can’t hit something something at a % of C, if there are a bunch of stars in the way.

The rise times of all of the flares were less than one minute, and the flares then decayed over about an hour.One source flared once to a peak luminosity of 9 × 1040 erg per second; the other flared five times to 1040 erg per second.
Spectral signal in halo stars, ETI suspected.
