Co-evolution of massive black holes and their host galaxies at high redshift: discrepancies from six cosmological simulations and the key role of JWST
Melanie Habouzit, Masafusa Onoue, Eduardo Banados +7
The James Webb Space Telescope will have the power to characterize high-redshift quasars at z>6 with an unprecedented depth and spatial resolution. While the brightest quasars at s…
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…
Metallicity Evolution of Damped Lyman-alpha Systems out to z~5
Marc Rafelski, Arthur M. Wolfe, J. Xavier Prochaska +2
We present chemical abundance measurements for 47 damped Lyman-alpha systems (DLAs), 30 at z>4, observed with the Echellette Spectrograph and Imager and the High Resolution Echelle…
