We present the largest, publicly available sample of damped Lyα systems (DLAs) along the lines of sight of Swift-discovered gamma-ray bursts (GRBs) in order to investigate the environmental properties of long GRB hosts in the z = 1.8–6 redshift range...

The most metal-poor damped Lyα systems: An insight into dwarf galaxies at high redshift (2015)
Journal Article
Cooke, R., Pettini, M., & Jorgenson, R. (2015). The most metal-poor damped Lyα systems: An insight into dwarf galaxies at high redshift. Astrophysical Journal, 800(1), Article 12. https://doi.org/10.1088/0004-637x/800/1/12

In this paper we analyze the kinematics, chemistry, and physical properties of a sample of the most metal-poor damped Lyα systems (DLAs), to uncover their links to modern-day galaxies. We present evidence that the DLA population as a whole exhibits a... Read More about The most metal-poor damped Lyα systems: An insight into dwarf galaxies at high redshift.

We build a sample of distant (D > 80 kpc) stellar halo stars with measured radial velocities. Faint (20 < g < 22) candidate blue horizontal branch (BHB) stars were selected using the deep, but wide, multi-epoch Sloan Digital Sky Survey photometry. Fo...
