| Abstract: We use 13 years of data collected by the Large Area Telescope (LAT) aboard Fermi to search for a cumulative signal from undetected Globular Clusters. We aim to associate the gamma-rays detected with LAT with our globular clusters using a stacked population of 36 high latitude targets not detected in the Fermi Point Source Catalog (4FGL). So far, Fermi has detected 32 Globular Clusters (GCs) which make them a feasible target for studies of gamma-rays. Control fields used in this analysis were selected from a library of fields randomly distributed across the sky by matching the Galactic distribution of the target clusters. We find that the stacked population of undetected globular clusters has a significant separation in cumulative likelihood from the stack of control fields. We also investigate correlations between the stack luminosity and detected cluster observables, such as distance, absolute magnitude (i.e., mass), and stellar encounter rate. |
