The Rapid Decline in Metallicity of Damped Ly-alpha Systems at z~5
Marc Rafelski, Marcel Neeleman, Michele Fumagalli +2
We present evidence that the cosmological mean metallicity of neutral atomic hydrogen gas shows a sudden decrease at z>4.7 down to <Z>=-2.03(+0.09-0.11), which is 6 sigma deviant f…

The Fundamental Plane of Damped Lyman Alpha Systems
Marcel Neeleman, Arthur M. Wolfe, J. Xavier Prochaska +1
Using a sample of 100 H I - selected damped Lyman alpha (DLA) systems, observed with the High Resolution Echelle Spectrometer on the Keck I telescope, we present evidence that the…
