VANDELS is a new, ultra-deep, optical spectroscopic survey of the high-redshift Universe using the VIMOS spectrograph on the VLT telescope. Using unprecedentedly long integration times (20-80 hours on-source), VANDELS will produce high signal-to-noise spectra covering the rest-frame UV/optical of galaxies within the redshift interval 1 z 7. Moreover, by targeting samples drawn from the CANDELS HST imaging surveys of the GOODS-S and UKIDSS UDS fields, galaxiestargeted by VANDELS benefit from the very best available multi-wavelength ancillary data. The main focus of the this PhD project will be to derive physical parameters (i.e. age, stellar mass, metallicity etc) for the VANDELS galaxies by performing spectro-photometric modelling of the combined spectra and multi-wavelength photometry, using multi-component SED models. Initially the project will focus on analysing passive galaxies at redshift z 1.5, attempting to break the well known age-metallicity degeneracy and comparing stellar masses derived from SED fitting with dynamical masses derived from the VANDELS spectra and HST imaging.

VANDELS是使用VLT望远镜上的VIMOS光谱仪对高红移宇宙进行的一项新的超深光学光谱调查。使用前所未有的长积分时间（20-80小时的源），VANDELS将产生高信号噪声光谱覆盖的其余帧UV/光学的星系内的红移间隔1 z 7。此外，通过从CANDELS HST成像调查GOODS-S和UKIDSS UDS字段中提取的样本，VANDELS所针对的星系受益于最好的多波长辅助数据。这个博士项目的主要重点将是通过使用多组分SED模型对组合光谱和多波长光度学进行分光光度学建模来获得VANDELS星系的物理参数（即年龄，恒星质量，金属丰度等）。最初，该项目将侧重于分析红移z 1.5的被动星系，试图打破众所周知的年龄金属丰度简并，并比较来自SED拟合的恒星质量与来自VANDELS光谱和HST成像的动力学质量。
