Description
Most of the matter in the universe is invisible and is known as dark matter (DM). Weakly Interacting Massive Particles (WIMPs) are possible theoretical candidates to explain DM. Hypothetically, WIMPs can be detected indirectly by their annihilation or decay products. A possible product is gamma ray. Many DM profile models predict higher density of WIMPs near the Galactic center. In this work, we consider monochromatic gamma-ray emission from the Galactic center region measured by the Large Area Telescope (LAT), the main instrument onboard the Fermi Gamma-ray Space Telescope. We present preliminary results of the analysis of gamma-ray spectral lines to search for DM annihilation or decay signals using the latest version of the LAT data.
