We investigate the Lyα and UV continuum morphology of one of the most luminous known Lymana emitting galaxies (the 'Coup Fourré Galaxy'), associated with a z = 2.3 damped Lyα absorption system in the spectrum of the QSO PHL 957. The galaxy is observed with the Hubble Space Telescope Wide-Field Planetary Camera 2 (HST WFPC2), through a narrow filter (F410M) corresponding to rest-frame Lyα for a total exposure time of 41.2 ks, plus shorter exposures in F555W and F814W. In all three passbands, the galaxy is resolved into a close (∼0.35 arcsec) pair of two components, CFgA and CFgB, both …
