Abstract (from CDS):

We report the spectroscopic confirmation of a compact Lyα emitting galaxy at z=5.721. A FORS2 spectrum of the source shows a strong asymmetric line with a flux of 5x10–17erg/s/cm2, making it one of the brightest Lyα emitting galaxies at this redshift, and a line-of-sight velocity dispersion of 400km/s. We also have a tentative detection of a second, narrower component that is redshifted by 400km/s with respect to the main peak. A FORS2 image shows that the source is compact, with a FWHM of 0.5", which corresponds to 3.2kpc at this redshift. This source is a brighter example of J1236.8+6215 (Dawson, 2002ApJ...570...92D), another Lyα emitting galaxy at z∼5.2.
