The Wide Field Imager Lyman-Alpha Search (WFILAS) for Galaxies at Redshift ~5.7: I. A Spatially Compact Lyman-alpha Emitting Galaxy at Redshift 5.721
Abstract
We report the spectroscopic confirmation of a compact emitting galaxy at z=5.721. A FORS2 spectrum of the source shows a strong asymmetric line with a flux of 5×10-17 erg s-1 cm-2, making it one of the brightest emitting galaxies at this redshift, and a line-of-sight velocity dispersion of 400 km s-1. We also have a tentative detection of a second, narrower component that is redshifted by 400 km s-1 with respect to the main peak. A FORS2 image shows that the source is compact, with a FWHM of 05, which corresponds to 3.2 kpc at this redshift. This source is a brighter example of J1236.8+6215 Dawson02, another \ emitting galaxy at z5.2.
