Title: \boldmath Probing the Most Luminous Lyman Break Galaxies at z~3

Abstract: We propose to use GMOS-N to carry out long-slit spectroscopic observations to establish a sample of the most luminous Lyman Break Galaxies (LBGs)(22.5<R_\rm AB<23.0) at z~3 in the NOAO Deep Wide Fields Survey (NDWFS) Bootes field. We have carried out new deep U imaging in the Bootes field down to 25.5 AB (5\sigma), using Large Binocular Cameras (LBCs) on the 2\times8.4-m Large Binocular Telescope (LBT) and selected ~15,000 LBG candidates in the 9 deg^2 field down to R_AB=25.5. This is the widest LBG survey to date, allowing us to establish a sample of the most UV luminous LBGs that are difficult to select in previous small area surveys. Our spectroscopic observations will enable us to (1) establish the largest complete sample for the brightest LBGs so far, (2) measure the LBGs luminosity function (LF) at the bright end for the first time, (3) study the basic physical properties of these UV-luminous galaxies with follow-up observations. Our sample will probe the most extreme star forming galaxies and constrain the formation and evolution of the largest structure of the universe at the peak of cosmic star formation. This project will be an important part of the PI's thesis.
