The most metal-rich damped Lyman alpha systems at z>1.5 I: The Data
Trystyn A. M. Berg, Marcel Neeleman, J. Xavier Prochaska +2
We present HIRES observations for 30 damped Lyman alpha systems, selected on the basis of their large metal column densities from previous, lower resolution data. The measured meta…
Probing the Physical Conditions of Atomic Gas at High Redshift
Marcel Neeleman, J. Xavier Prochaska, Arthur. M. Wolfe
A new method is used to measure the physical conditions of the gas in damped Lyman-alpha systems (DLAs). Using high resolution absorption spectra of a sample of 80 DLAs, we are abl…
Reverberation Mapping of the Kepler-Field AGN KA1858+4850
Liuyi Pei, Aaron J. Barth, Greg S. Aldering +40
KA1858+4850 is a narrow-line Seyfert 1 galaxy at redshift 0.078 and is among the brightest active galaxies monitored by the Kepler mission. We have carried out a reverberation mapp…
Reproducing the Kinematics of Damped Lyman-alpha Systems
Simeon Bird, Martin Haehnelt, Marcel Neeleman +3
We examine the kinematic structure of Damped Lyman-alpha Systems (DLAs) in a series of cosmological hydrodynamic simulations using the AREPO code. We are able to match the distribu…
