Ly-Alpha是研究宇宙学和星系形成的高z探测的主要目标,但Ly-Alpha辐射转移物理使这些样本的解释复杂化。我们已经证明,PMAS H-α运动学地图与UV成像、UV光谱和21厘米HI观测相结合,对于建立星系中Ly-α辐射传输的相干经验图像至关重要。H-α星系的分光光度法直接追踪本征Ly-α辐射场,从而限制了Ly-α辐射传输的初始条件。我们正计划完成我们的PMAS扩展Ly-Alpha参考样本的观测活动--通过观察其余10个星系,对28个相干选择的附近实验室星系进行传统的调查,用Ly-Alpha中的HST成像。
英文摘要
Ly-alpha is a prime target in high-z surveys studying cosmology and galaxy formation, but Ly-alpha radiation transfer physics complicate the interpretation of those samples. We already demonstrated that PMAS H-alpha kinematic maps in concert with UV imaging-, UV spectroscopy and 21cm HI observations are vital to build a coherent empirical picture of Ly-alpha radiative transfer in galaxies. Spectrophotometry of galaxies in H-alpha trace directly the intrinsic Ly-alpha radiation field and thus constrain the initial conditions of the Ly-alpha radiative transfer. We are planning to complete our PMAS observational campaign of the Extended Ly-alpha Reference Sample - a legacy survey of 28 coherently selected nearby laboratory galaxies imaged with HST in Ly-alpha by observing the remaining 10 galaxies.
