论文摘要
我们研究了来自不确定的红移活跃的银河核（AGN）ver J0521+211的光子轴基粒子（ALP）振荡对TEV伽马射线光谱不规则的影响。伽马射线光谱通过Fermi-Lat和Veritas在2013年和2014年通过三个磁通状态进行测量。我们将合并的约束对ALP参数（$ M_A，G_A，G_ {Aγ} $）进行了这些状态，并与这些状态进行测试，并测试对Alp terfagalactic背景光（EBL）的吸收效果，并对Redshift limits Seneaim效应。 $ z_0 \ sim \ mathcal {o}（0.1-0.3）$。 ver J0521+211设置的99％$ \ rm c.l. $ photon-alp组合约束约合在$ g_ {aγ} \ gtrsim 2.0 \ times 10^{ - 11} { - 11} \ rm \ rm \，gev^{-1} $ for $ 1.0 \ times $ 1.0 \ times10 \ times10^}}}}} {-9} {-9} {-9}} \ Lessim 1.0 \ times10^{ - 7} \，{\ rm ev} $。我们发现红移极限方案与光子-ALP约束之间没有明确的联系。被低估和高估的红移都会影响约束结果。
We investigate the photon-axionlike particle (ALP) oscillation effects on TeV gamma-ray spectral irregularities from the uncertain redshift active galactic nuclei (AGN) VER J0521+211. The gamma-ray spectra are measured by Fermi-LAT and VERITAS with the three flux states in 2013 and 2014. We set the combined constraints on the ALP parameter ($m_a, g_{aγ}$) space with these states and test the extragalactic background light (EBL) absorption effect on ALP constraints with the redshift limit scenarios $z_0\sim\mathcal{O}(0.1-0.3)$. The 99% $\rm C.L.$ photon-ALP combined constraints set by VER J0521+211 are roughly at $g_{aγ} \gtrsim 2.0\times 10^{-11} \rm \, GeV^{-1}$ for $1.0\times10^{-9} \, {\rm eV} \lesssim m_a \lesssim 1.0\times10^{-7} \, {\rm eV}$. We find no clear connection between the redshift limit scenarios and the photon-ALP constraints. Both the underestimated and overestimated redshifts can affect the constraint results.
