Galactic-scale Outflow at z>4 revealed by Adaptive Optics
[Abstract]
Characterization of the large-scale galactic outflow is very important to understand many astrophysical phenomena at high-z, such as the escape of LyA photons from the galaxy, the relation between the galaxy populations, and IGM metal-enrichment history. Although galactic outflows are ubiquitously found in star-forming galaxies at 2
