Hα emission in the outskirts of galaxies at <i>z</i> = 0.4
This paper reports detections of H$α$ emission and stellar continuum out to approximately 30 physical kpc, and H$α$ directionality in the outskirts of H$α$-emitting galaxies (H$α$ emitters) at $z=0.4$. This research adopts narrow-band selected H$α$ emitters at $z=0.4$ from the emission-line object catalog by Hayashi et al. (2020), which is …
