Searching for blazars among the fermi-LAT unidentified sources in the galactic plane
We have searched the WISE mid-IR catalog to identify counterparts of yet unassociated bright FermiLAT γ-ray sources located in the Galactic plane. These GeV sources could have a galactic origin, most likely, or they could be extragalactic objects such as blazars, or even a new type of γ-ray emitter....

| Sumario: | We have searched the WISE mid-IR catalog to identify counterparts of yet unassociated bright FermiLAT γ-ray sources located in the Galactic plane. These GeV sources could have a galactic origin, most likely, or they could be extragalactic objects such as blazars, or even a new type of γ-ray emitter. The key to understand these objects and determine their physical nature is the identification of their counterparts at other wavelengths. Due to the deficit of blazars discovered so far in the Galactic plane, it is expected that many of the unassociated Fermi sources are blazar. We have searched into these γ-ray unidentified sources looking for non-thermal emission in the IR. We have found only 1 out of 10 γ-ray Fermi sources to have a WISE blazar candidate within their position error regions. © 2013 Sociedade Brasileira de Fisica. All Rights Reserved. |
