论文摘要
我们提出了Zodipy，这是一种现代且易于使用的Python包装，用于建模由任意太阳系观察者看到的十二生座发射，可用于去除天文学数据中的热发射和散射的阳光。该代码实现了Cobe漫射红外背景实验（DIRBE）星际尘埃模型和Planck扩展，该模型允许在1.25-240 $ $ M范围内的红外波长和30-857 GHz范围内的微波频率下进行红外波长的黄道发射预测。预测的黄道排放可能被推断为内置模型未涵盖的频率和波长，以产生未来实验的预测。 Zodipy试图通过为社区提供易于使用的界面来测试当前和将来的模型，从而实现新的星际尘埃模型的开发。我们证明了如何通过为Dirbe实验创建模拟的黄道十二片发射时间播放来使用该软件，并表明这些软件与与Dirbe Zodiacal Light Predict toction Software一起生成的相应的时间流相一致。正如Dirbe所预测的那样，我们还制作了黄道十二生纳发射的图形，并将其与Dirbe校准的个体观测值（CIO）进行了比较。
We present ZodiPy, a modern and easy-to-use Python package for modeling the zodiacal emission seen by an arbitrary Solar System observer, which can be used for the removal of both thermal emission and scattered sunlight from interplanetary dust in astrophysical data. The code implements the COBE Diffuse Infrared Background Experiment (DIRBE) interplanetary dust model and the Planck extension, which allows for zodiacal emission predictions at infrared wavelengths in the 1.25-240 $μ$m range and at microwave frequencies in the 30-857 GHz range. The predicted zodiacal emission may be extrapolated to frequencies and wavelengths not covered by the built-in models to produce forecasts for future experiments. ZodiPy attempts to enable the development of new interplanetary dust models by providing the community with an easy-to-use interface for testing both current and future models. We demonstrate how the software can be used by creating simulated zodiacal emission timestreams for the DIRBE experiment and show that these agree with corresponding timestreams produced with the DIRBE Zodiacal Light Prediction Software. We also make binned maps of the zodiacal emission as predicted to be observed by DIRBE and compare them with the DIRBE calibrated individual observations (CIO).
