I dont know how reputable the independant is, or the Journal of Publications of the Astronomical Society of the Pacific (probably not very). But theyre saying in their paper that this signal is 'probably aliens'. Seems like a rather big call to make, failing any other evidence. They do mention the authors, the university they hail from, and the journal they published in. Im overseas at the moment, so i havent gone scrounging for its citation index.
