SUMMARY:Discovery of gamma-ray Emission from Andromeda  Galaxy\, NPAC 
 (Nuclear/Particle/Astro/Cosmo) Forum\, Hakki Ogelman\, University of W
 isconsin at Madison
DESCRIPTION:2 years worth of archival FERMI-LAT data was used to searc

\nemission from the Andromeda galaxy\; the data sho
 w no noticeabla gamma-ray image.On-off source aperture photometry usin
 g a CO image template shows a 7 sigma excess in the on-source aperture
 s in comparison to the off-source apertures. yielding a flux of (4.95 
 +/- 0.71`)x10^(-8) photonscm^-2 s^-1 at energies E>100 MeV. The likely
  origin of this flux will be discussed in terms of the cosmic-ray cont
 ent and the interstellar gas at Andromeda.
