These particles could be detected through their mixing with photons in external electromagnetic fields. Here, we provide a short review over ALP searches that utilize astrophysical $\\gamma$-ray observations. We summarize current bounds as well as future sensitivities and discuss the possibility that ALPs alter the $\\gamma$-ray opacity of the Universe.", "revisions": [ { "version": "v1", "updated": "2016-11-23T13:36:03.000Z" } ], "analyses": { "keywords": [ "axionlike particles", "gamma-ray observations", "external electromagnetic fields", "cold dark matter", "common prediction" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
