Multi-component SED fitting of VANDELS star-forming galaxies with BAGPIPES

用风笛对z&gt；2.4处恒星形成星系的多组分SED拟合(VANDELS光谱+光度法)(Carnall等人。2018)，基于单个物体和光谱+光度堆栈。SED拟合将根据从堆叠的UV光谱中提取的金属丰度和粉尘测量结果进行限制(例如，Cullen等人，2018、2019年)。目标是将恒星形成星系的典型SFH限制为红移和恒星质量的函数，并与爱丁堡的FiBY和SIMBA流体动力学模拟进行比较。风笛返回的拟合物理参数和不确定性可能构成VANDELS于2020年9月发布的最终数据的一部分。

Multi-component SED fitting of star-forming galaxies at z>2.4 (VANDELS spectra + photometry) with BAGPIPES (Carnall et al. 2018), based on individual objects and spectra+photometry stacks. The SED fitting will be constrained according to metallicity and dust measurements extracted from the stacked UV spectra (e.g. Cullen et al., 2018, 2019). The goal is to constrain the typical SFHs of star-forming galaxies as a function redshift and stellar mass and to compare with the FiBY and SIMBA hydrodynamical simulations run in Edinburgh. The fitted physical parameters and uncertainties returned by BAGPIPES could form part of the final VANDELS data release in September 2020.
