纺纱粉尘排放光谱解析近似的推导

Derivation of an Analytical Approximation of the Spectrum of Spinning Dust Emission

Matthew Stevenson

摘要:

提出了旋转尘埃发射光谱的解析函数。它是通过仔细的近似应用程序得出的,每一步都经过了数值计算的测试。这种方法确保了准确性,同时提供了直观的物理图像。最后的结果可能是有用的拟合异常微波发射观测,作为证明了与普朗克观测英仙座分子云。人们希望,这将导致更广泛的考虑旋转尘埃模型时,解释微波连续观测,它将提供一个标准的框架,解释和比较各种异常的微波发射观测。

英文摘要:

An analytical function for the spectrum of spinning dust emission is presented. It is derived through the application of careful approximations, with each step tested against numerical calculations. This approach ensures accuracy while providing an intuitive picture of the physics. The final result may be useful for fitting of anomalous microwave emission observations, as is demonstrated by a comparison with the Planck observations of the Perseus Molecular Cloud. It is hoped that this will lead to a broader consideration of the spinning dust model when interpreting microwave continuum observations, and that it will provide a standard framework for interpreting and comparing the variety of anomalous microwave emission observations.
