Abstract

The existence of light bosons may help to explain the strong-CP1 problem of quantum chromodynamics (QCD), the dark matter problem of cosmology and may be related to quintessence. Here we argue that low to medium resolution spectroscopy of magnetars, pulsars, and quasars, and the study of the radio light curves of magnetized pulsars can be used to search for photon-particle mixing features. In particular, these observations can be used as independent tests for the existence of light bosons, such as the axion, which are 3-5 orders more sensitive than current laboratory experiments over a broad particle mass range. Currently planned missions will make the astrophysical detection of light bosons observationally feasible.
