Lyman Break Galaxies at z~1.8-2.8: GALEX/NUV Imaging of the Subaru Deep Field

Understand

Abridged: A photometric sample of ~7100 V<25.3 Lyman break galaxies (LBGs) has been selected by combining Subaru/Suprime-Cam BVRci'z' data with deep GALEX/NUV imaging of the Subaru Deep Field.

• Follow-up spectroscopy confirmed 24 LBGs at 1.5<z<2.7.
• Among the optical spectra, 12 have Ly-alpha emission with rest-frame equivalent widths of ~5-60AA.
• The success rate for identifying LBGs as NUV-dropouts at 1.5<z<2.7 is 86%.
