Abstract We report the results from our analysis of the Fermi Large Area Telescope data for the Fermi unassociated source 2FGL J1906.5+0720, which is a high-ranked candidate pulsar. In order to better study our target, we first update the ephemeris for PSR J1907+0602, which is used to help remove any possible contamination due to strong emission from this nearby pulsar. From our analysis, 2FGL J1906.5+0720 is confirmed to have a significant low-energy cut-off at ∼ 1 GeV in its emission (14 σ–18 σ significance), consistent with those seen in young pulsars. We search for pulsations but no spin frequency signals are found in a frequency range of 0.5–32 Hz. No single model can fully describe the source's overall Fermi γ-ray spectrum, and the reason for this is the excess emission detected at energies of ≥ 4 GeV. The high-energy component possibly indicates emission from a pulsar wind nebula, when considering 2FGL J1906.5+0720 as a young pulsar. We conclude that 2FGL J1906.5+0720 is likely a pulsar based on the emission properties we have obtained, and observations at other energies are needed in order to confirm its pulsar nature.
