The VLT LBG Redshift Survey

Surveying Lyman break galaxies in the foreground of bright quasars







The Survey

The VLT LBG Redshift Survey (VLRS) primary aim is to investigate the links between galaxies and the inter-galactic medium (IGM) at redshifts of ~ 3. This is being conducted via a large redshift survey of Lyman Break Galaxies (LBGs) across a large number of fields centred on bright z ~ 3 QSOs. These pages provide information and contact details for the project.

The above image shows the ~ 2,100 VLT VIMOS z > 2 galaxy spectra sorted from left to right in order of redshift. Wavelength goes from bottom (370 nm) to top (670 nm) in the image and the Lyman Break (rest fram 121.6 nm) is seen as the curve separating the light (i.e. top/higher wavelength) and dark (bottom/lower wavelength) regions. Several absorption features (e.g. SiII 1260, OI+CII 1302, CII 1336, SiIV 1400, SiIV 1402, CIV 1550) are also discernable in across some of the image (particularly at the low redshift/left hand side of the image) as dark curves above the Lyman break.
