Energy-dependent periodicities of LS I +61${}^{\circ }$ 303 in the GeV band

M. Chernyakova, D. Malyshev, A. Neronov +1

LS I +61${}^{\circ }$303 is a rare representative of the gamma-ray binaries with a compact object known to be a pulsar. We report on the periodicity and spectral analysis of this source…
