General Description

We propose to observe the quasar PKS 1448-232 (z=2.208; V=16.9) with UVES
 at very high resolution (R sim 75,000) in order to study the fine structure in the
 absorption lines of intervening OVI and CIV systems. The main goal of this project
 is to investigate those OVI and CIV absorbers that are intrinsically narrow, with
 Doppler parameters (b-values) less than about 7 km s-1. These systems are not resolved
 in currently existing intermediate-resolution UVES spectra. With these new UVES
 data we will be able to accurately measure the component structure and line widths
 of the intervening OVI and CIV absorbers towards PKS 1448-232. Only these new data
 will allow us to derive reliable line-width temperature constraints and OVI/CIV
 column density ratios. These parameters are crucial to unveil the mechanisms that
 ionize the intergalactic medium at z approx 2.
