论文摘要
最近，我们在圆形极化度和线性极化位置角度使用了Pulsar极化数据集，与已建立的理论，椭圆度参数和线性极化位置角有关，由未极化的光子累积，同时进行光子-Alp振荡，并在磁性介质内部进行磁磁介质。这为我们提供了参数值，例如ALP质量及其与光子的耦合。为了进一步测试这一点，我们现在改用不同的波段，除了早期的21 cm波长，并检查模型的有效性。在这里，我们在两个不同的波段中观察到的相同脉冲星的圆极化程度上使用了两个数据集。我们展示了存在ALP质量的复合产品变量及其与光子耦合的复合产品变量之间的相关性。我们还检查了我们的模型假设，即一种物理效应（即ALP-Photon混合）是否足以（忠实地估算ALP参数）。最后，我们通过描述可能包含在模型中的其他相关物理效应来解释脉冲星的圆极化程度，而与其观察的工作波长无关。
Recently, we have used, pulsar polarisation datasets, on circular polarisation degree & linear polarisation position angle, to relate with well established theories, on ellipticity parameter and linear polarisation position angles, accrued by unpolarised photons, while undergoing photon-ALP oscillations, inside a magnetised medium. This has given us parameter values such as ALP mass and its coupling to photons. To further test this, we now switch to different wavebands, other than earlier 21 cm wavelength, and check for the validity of our model. Here we use two data sets on circular polarisation degree of identical pulsars observed in two different wavebands. We show, correlation between these two new sets of data and our model using the composite product variable of ALP mass and its coupling to photons, exist. We also check whether our model hypothesis that one physical effect, namely ALP-photon mixing is sufficient to, estimate ALP parameters, faithfully, or not. We conclude by describing other pertinent physical effects that may be included into our model to explain the circular polarisation degree of pulsars, independent of its operating wavelength of observation.
