| 英文摘要 | We searched for the gamma-ray signal from M33, one of the largest galaxies in the Local Group, using the Pass8 data from the Fermi Large Area Telescope (LAT). No statistically significant gamma-ray emission has been detected in the direction of M33, and we report a new upper limit of the high-energy (>100 MeV) photon flux of 2.3 x 10(-9) ph cm(-2) s(-1), which is stricter than previous constraints and implies a cosmic ray density for M33 that is lower than that suggested previously. The current limit is still, however, in agreement with the correlation of star formation rate and gamma-ray luminosity inferred from the Local group galaxies and a few nearby starburst galaxies. |
