Unveiling the Secrets of Metallicity and Massive Star Formation Using DLAs along Gamma-ray Bursts
A. Cucchiara, M. Fumagalli, M. Rafelski +4
We present the largest, publicly available, sample of Damped Lyman- systems (DLAs) along Gamma-ray Bursts (GRB) line of sights in order to investigate the environmental properti…
The History of R-Process Enrichment in the Milky Way
Sijing Shen, Ryan Cooke, Enrico Ramirez-Ruiz +3
We investigate the production sites and the enrichment history of -process elements in the Galaxy, as traced by the [Eu/Fe] ratio, using the high resolution, cosmological zoom-i…
The most metal-poor damped Lyman alpha systems: An insight into dwarf galaxies at high redshift
Ryan Cooke, Max Pettini, Regina A. Jorgenson
In this paper we analyze the kinematics, chemistry, and physical properties of a sample of the most metal-poor damped Lyman-alpha systems (DLAs), to uncover their links to modern-d…
Carbon-Enhanced Metal-Poor Stars: Relics from the Dark Ages
Ryan Cooke, Piero Madau
We use detailed nucleosynthesis calculations and a realistic prescription for the environment of the first stars to explore the first episodes of chemical enrichment that occurred…
