论文摘要
我们介绍了前景，这是一种生成的星系光谱分布（SED）套件，封装了许多天体物理领域中SED方法的最佳实践。潜在客户有两个流行的恒星人口图书馆（BC03和Emiles）的家庭，以及构建恒星形成和金属历史的各种方法。它通过使用Charlot＆Fall衰减模型对灰尘进行建模，并使用Dale远红外模板重新排放。它还具有通过包含一个简单的AGN和热圆环模型来对AGN进行建模的能力。最后，它利用映射-III摄影表来产生线排放功能。我们通过应用于鲨鱼星系组半分析代码来测试前景的生成和反转效用，并通过这些结果告知，最终的紫外线对远红外光度目录产生了拟合，该目录由银河系和大规模组装调查（GAMA）产生。作为前景测试的一部分，我们还产生了一系列简单的光度恒星质量近似值，涵盖了观察到的框架和静止框架光度法的一系列过滤器。
We introduce ProSpect, a generative galaxy spectral energy distribution (SED) package that encapsulates the best practices for SED methodologies in a number of astrophysical domains. ProSpect comes with two popular families of stellar population libraries (BC03 and EMILES), and a large variety of methods to construct star formation and metallicity histories. It models dust through the use of a Charlot & Fall attenuation model, with re-emission using Dale far-infrared templates. It also has the ability to model AGN through the inclusion of a simple AGN and hot torus model. Finally, it makes use of MAPPINGS-III photoionisation tables to produce line emission features. We test the generative and inversion utility of ProSpect through application to the Shark galaxy formation semi-analytic code, and informed by these results produce fits to the final ultraviolet to far-infrared photometric catalogues produces by the Galaxy and Mass Assembly Survey (GAMA). As part of the testing of ProSpect, we also produce a range of simple photometric stellar mass approximations covering a range of filters for both observed frame and rest frame photometry.
