Axion limits from the 10-year gamma-ray emission 1ES 1215+303
We present the limits on photon to axionlike particle (ALP) coupling from the 10-year period observations of the TeV BL Lacertae blazar 1ES1215+303 (with redshift z=0.130). The contemporaneous gamma-ray spectra are measured by the collaborations Fermi-LAT and VERITAS with five flux phases from 2008...

| description | We present the limits on photon to axionlike particle (ALP) coupling from the 10-year period observations of the TeV BL Lacertae blazar 1ES1215+303 (with redshift z=0.130). The contemporaneous gamma-ray spectra are measured by the collaborations Fermi-LAT and VERITAS with five flux phases from 2008 to 2017, including four low states and one flare. Using these flux phases, we show the spectral energy distributions (SEDs) under the null/ALP hypotheses and set the combined limit on ALP. The 95% C.L. combined limit set by 1ES1215+303 with the 10-year gamma-ray data is roughly at the photon-ALP coupling constant gaγ≳1.5×10−11,GeV−1 for the ALP mass 5.0×10−10eV≲ma≲1.0×10−7eV. |
