No Compact Radio Emission from the Proposed Blazar Candidate Counterpart for the Fermi Source 4FGL J1848.7-0129.

FREY S., PERGER K. and GABANYI K.E.

Abstract (from CDS):

By assessing available radio data, we argue that the recently proposed new counterpart for the Fermi γ-ray source 4FGL J1848.7-0129 is unlikely to be a blazar. The radio source coincident with a Chandra X-ray point source is extended on ∼10″ angular scale, has no detected compact component (3 GHz flux density ≲1 mJy), and its radio spectrum is steep. These properties contradict to what is expected for blazars with relativistically beamed radio jet emission.
