Spatially resolved Lyman-alpha emission from a virtual dwarf galaxy

摘要

In the context of the first light of MUSE, Integral Field Unit (IFU) spectrograph of second generation installed recently at VLT, we compute mock IFU Lyman-alpha (lya) observations of a virtual dwarf galaxy, to help understanding and interpreting forthcoming observations. This study is an extension of the work carried out in Verhamme et al. (2012), where we studied the spatially integrated lya properties of a dwarf galaxy. With the same data, we now investigate the spatial variations of lya spectra.
