Description
There are thousands of identified gamma-ray sources in our Milky Way. Many of these sources have been studied using the Fermi-LAT satellite, which is sensitive to photons in the energy range between 20 MeV and 300 GeV. Among the gamma-ray excesses detected with the Fermi-LAT, there are candidates that no one has observed before, which are designated unassociated. This study uses data from the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory to identify some of these Unassociated Fermi Objects (UFOs). The HAWC Observatory is sensitive to gamma rays in the range between 500 GeV and 100 TeV, the highest energy gamma rays ever detected. By correlating these two unique datasets, we will be not only identifying previously unassociated objects but will also be uncovering the most powerful accelerators in our Galaxy. Our results found at least one significant association from the gamma-ray source 3HWC J1837-066 from ~15 keV up to ~100 TeV. To pursue this study even further, we will study the energy spectrum measured by the three experiments to pinpoint the actual astrophysical object behind the gamma-ray emission. We will use these studies to prepare a Target-Of-Opportunity proposal to request observation time with the Swift-XRT instrument, which operates at even lower energy (from 0.2 to 10 keV).
