PMAS Observations "Halpha kinematics of the Extended Lyman alpha Reference Sample"

我们建议观察扩展莱曼阿尔法参考样本（eLARS）的成员，这是一个对附近42个实验室恒星形成星系的全色调查，我们正在研究共振莱曼辐射转移的复杂物理学。eLARS星系中Ha发射的空间分辨光谱在真实的和频率空间中追踪了本征Lya辐射场，从而限制了Lya辐射通过星际介质传输的初始条件。结合我们的HST成像和光谱学以及VLA HI观测，这些数据对于建立星系中Ly辐射传输的相干图像至关重要，从而支持对现有和即将到来的高红移Lya发射体样品的解释。

We propose to observe members of the Extendend Lyman Alpha Reference Sample (eLARS), a pan-chromatic survey of 42 nearby laboratory star-forming galaxies in which we are studying the complex physics of the resonant Lyman radiative transfer. Spatially resolved spectroscopy of Ha emission in the eLARS galaxies traces the intrinsic Lya radiation field in real and frequency space, therefore constraining the initial conditions of the Lya radiation transport through the interstellar medium. In conjunction with our suite of HST imaging and spectroscopy and VLA HI observations, these data will be vital to build a coherent picture of Ly radiative transfer in galaxies, thereby supporting the interpretation of existing and upcoming high-redshift Lya emitter samples.
