Recent evidence for Gamma-ray Line Emission from Fermi-LAT:
WIMP or artifact?

Meng Su

Harvard CfA

The recent claims of a gamma-ray line in the Galactic center at 130 GeV have generated excitement, not least because it could be a signal of dark matter annihilation. I will summarize the current state of the observations of the Galactic center, galaxy clusters, and unassociated halo objects. I will also discuss possible systematic of the Fermi-LAT instrument that might contaminate the line detection.
