The nature of the unidentified GeV source 4FGL J1842.5-0359
Abstract
A bright X-ray source within the error ellipse of the unidentified Fermi source 4FGL J1842.5-0359 has been serendipitously detected with XMM-Newton. The spectra of the X-ray and gamma-ray sources suggest that they are associated with a high-mass gamma-ray binary. This interpretation is supported by the presence of a NIR source within the error circle of the X-ray source. To verify the apparent positional coincidence of the X-ray and NIR sources, we request a short high-resolution ACIS observation.
