我们考虑了高红移1a型超新星的光子通过与星系间介质中的伪标量轴子场混合而变暗。我们使用对数正态概率分布和冻结在磁场中的磁场和电子密度模型。假设磁场是在早期宇宙中产生的，我们无法获得足够的调光，以便在不违反调光频率依赖的界限的情况下解释表观加速度。我们还表明，任何导致光学光度降低的轴子混合也会导致来自中间红移物体的紫外线偏振显著降低，这可能在未来被检测到。
We consider the dimming of photons from high redshift type 1a supernovae through mixing with a pseudoscalar axion field in the intergalactic medium. We model the magnetic field and electron density using a log-normal probability distribution and frozen in magnetic fields. Assuming the magnetic fields are produced in the early universe we are unable to obtain sufficient dimming in order to explain the apparent acceleration without violating the bounds on the frequency dependence of the dimming. We also show that any axion mixing leading to a reduction in optical luminosities would also lead to a significant reduction in the polarisation of UV light from intermediate redshift objects which may be detected in the future.
