String axiverse and gamma-ray spectral modulation of galactic pulsars
<!--HTML-->I discuss first the possible range of axion scales and couplings in string axiverse, and then the possibility to explain the recently noticed spectral modulation of gamma-rays from some galactic pulsars by the axion-photon-dark photon mixing realized in axiverse scenario.
