Hunting for treasures among the fermi unassociated sources: A multiwavelength approach
journal contribution
posted on 2023-05-17, 21:57 authored by Acero, F, Donato, D, Ojha, R, Stevens, J, Edwards, PG, Ferrara, E, Blanchard, J, James LovellJames Lovell, Thompson, DJThe Fermi Gamma-Ray Space Telescope has been detecting a wealth of sources where the multiwavelength counterpart is either inconclusive or missing altogether. We present a combination of factors that can be used to identify multiwavelength counterparts to these Fermi unassociated sources. This approach was used to select and investigate seven bright, high-latitude unassociated sources with radio, UV, X-ray, and γ-ray observations. As a result, four of these sources are candidates to be active galactic nuclei, and one to be a pulsar, while two do not fit easily into these known categories of sources. The latter pair of extraordinary sources might reveal a new category subclass or a new type of γ-ray emitter. These results altogether demonstrate the power of a multiwavelength approach to illuminate the nature of unassociated Fermi sources.
