Lyman alpha absorbers in 0.5<z<1.9 QSOs
Listed in IVOA Registry (Virtual Observatory)
We investigate the evolution and the statistical properties of the Ly{alpha} absorbers of the intergalactic medium (IGM) in the largely unexplored redshift range z=0.5-1.9.
Description
We use high-resolution (R>=30000) UV (STIS) and optical (VLT/UVES and Keck/HIRES) spectra of nine bright quasars with z_em_<1.94. The Ly{alpha} lines detected in the lines of sight (LOS) towards these quasars are evaluated with a software package which determines simultaneously the quasar continuum and the line profiles.
