Once in a while funny stuff happens. Neutrinos travel faster than light....and then they don't. There is at present a signal in the FermiLat data of ~ 130 billion electron volts from the Milky Way's center. Lots of high energy photons...not a lot of good explanations why. A mystery that intrigues experimentalists and theorists alike...or maybe not. The authors double check the instruments...and so far there is a funny collection of high energy photons near the Earth's limb,too. Mystery deepens...see: http://arxiv.org/abs/1209.4562

And yet, the very next paper: http://arxiv.org/abs/1209.4562 says that no systematic effect has been found.
The 130 GeV signal is new, exciting, statistically significant, and still in doubt. I'm interested in all papers pro and con. This is the most exciting thing in astronomy to day.

Oops... You were actually referring to this: http://arxiv.org/abs/1209.4548 paper... but we both linked to the second one.

Where on earth's limb, as in tangentially from a line passing through the galactic core?

I hope it doesn't get stronger as we get closer to December 21. :)
