Building the Bridge between Damped Lyα Absorbers and Lyman-break Galaxies

چکیده
In 2000, we started the program “Building the Bridge between Damped Lyman-α Absorbers and LymanBreak Galaxies: Lyα Selection of Galaxies” at the European Southern Observatory’s Very Large Telescope (VLT). This project is an attempt to use the Lyα selection of high-redshift galaxies to bridge the gap between absorptionand emission-line selected galaxies by creating a large database of z ≈ 3 galaxies belonging to the abundant population of faint (R > 25.5) galaxies associated to Damped Lyα Absorbers (DLAs). Here we present the first part of our program, namely results from a deep Lyα study of the field of the z = 2.85 DLA toward the quasar Q2138−4427.

We use deep HST STIS and NICMOS images of three spectroscopically confirmed galaxy counterparts of high-redshift damped Lyα (DLA) absorbers (one of which is a new discovery) to test the hypothesis that high-redshift DLA galaxies are Lyman-break galaxies. If this hypothesis is correct the emission properties of DLA galaxies must lie within the range of emission properties measured for Lyman-brea...
متن کاملOutflows in Galaxies and Damped Lyα Systems
Although quasar absorbers, and in particular Damped Lyman-alpha systems (DLAs) have proven a valuable tool to study the early Universe, their exact nature is so far poorly constrained. It has been suggested that outflows in galaxies might account for at least part of the DLA population. Observational evidences and models in support of this hypothesis are reviewed, including recent observations ...
متن کاملOn the Importance of Local Sources of Radiation for Quasar Absorption Line Systems
A generic assumption of ionization models of quasar absorption systems is that radiation from local sources is negligible compared with the cosmological background. We test this assumption and find that it is unlikely to hold for absorbers as rare as H I Lyman limit systems. Assuming that the absorption systems are gas clouds centered on sources of radiation, we derive analytic estimates for th...
متن کاملFirst Investigation of the Clustering Environment of Damped Lyman Α Absorbers at Z ≃
We report the first observations of the clustering environment of damped Lyman α absorption systems at z ≃ 4. Color selection and photometric redshifts were used to select 44 candidate Lyman-break galaxies brighter than IAB = 25.5 from deep BRI images of the 35 arcmin 2 field containing the quasar BR 0951−04. Multislit spectroscopy of 35 candidate galaxies was performed and 8 of these candidate...

We present results from an ongoing search for galaxy counterparts of a subgroup of Quasar Absorption Line Systems called Damped Lyα Absorbers (DLAs). DLAs have several characteristics that make them essential in the process of understanding how galaxies formed in the early universe and evolved to the galaxies we see today in the local universe. Finally we compare DLAs with recent findings of a ...
