Abstract (from CDS):

In the third Fermi catalogue (3FGL) there are 16 gamma-ray globular clusters. Following an analysis of the recently released Pass 8 data from the Fermi Large Area Telescope (LAT), we report the discovery of significant gamma-ray emission from M15 and NGC 6397, confirm that NGC 5904 is a gamma-ray-emitter and provide evidence of gamma-ray emission from NGC 6218 and 6139. Interestingly, in the globular clusters M15, NGC 6397 and 5904, millisecond pulsars (MSPs) have been found in the radio or X-ray, which strongly support the MSP origin of the gamma-ray emission. Owing to the relatively low luminosity of the gamma-ray emission, however, we do not find any evidence for gamma-ray pulsation or flux variability in these sources.
