PMAS observing campaign at Calar Alto 3.5m Telescope "Ionised haloes in the Lyman Alpha Reference Sample"

Ly-α是研究宇宙学和星系形成的高z探测中的主要目标，但Ly-α辐射转移物理使这些样本的解释变得复杂。我们已经证明，PMAS Halpha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Lypha辐射传输的连贯经验图像至关重要。Halpha星系的分光光度法直接追踪固有的Lypha辐射场，从而限制Lypha辐射传输的初始条件。现有的PMAS/LARR数据在视场和波长覆盖范围方面有限，并且不能捕获全部电离晕。在这里，我们建议进行一项初步研究，以绘制由Halpha和[OIII]追踪的具有PMAS/PPAK的LARS的电离气体范围。

Ly-alpha is a prime target in high-z surveys studying cosmology and galaxy formation, but Ly-alpha radiative transfer physics complicate the interpretation of those samples. We already demonstrated that PMAS Halpha kinematic maps in concert with UV imaging-, UV spectroscopy and 21cm HI observations are vital to build a coherent empirical picture of Lyalpha radiative transfer in galaxies. Spectrophotometry of galaxies in Halpha trace directly the intrinsic Lyalpha radiation field and thus constrain the initial conditions of the Lyalpha radiative transfer. The existing PMAS/LARR data are limited in field of view and wavelength coverage and does not capture the full ionised haloes. Here we propose a pilot study to map the ionised gas extent, traced by Halpha and [OIII], of LARS with PMAS/PPAK.
