The explosion energy of early stellar populations: The Fe-peak element ratios in low metallicity damped Lyman-alpha systems
Ryan Cooke, Max Pettini, Regina A. Jorgenson +3
The relative abundances of the Fe-peak elements (Ti-Zn) at the lowest metallicities are intimately linked to the physics of core-collapse supernova explosions. With a sample of 25…
Near-pristine gas at high redshifts: a window on early nucleosynthesis
Max Pettini, Ryan Cooke
It has now become recognised that damped Lyman alpha systems play an important role in helping us unravel the origin of chemical elements. In this presentation, we describe the mai…
A Broad Iron Line in LMC X-1
James F. Steiner, Rubens C. Reis, Andrew C. Fabian +6
We present results from a deep Suzaku observation of the black hole in LMC X-1, supplemented by coincident monitoring with RXTE. We identify broad relativistic reflection features…
The cold veil of the Milky Way stellar halo
A. J. Deason, V. Belokurov, N. W. Evans +7
We build a sample of distant (D > 80 kpc) stellar halo stars with measured radial velocities. Faint () candidate blue horizontal branch (BHB) stars were selected using…
A new, precise measurement of the primordial abundance of Deuterium
Max Pettini, Ryan Cooke
The metal-poor damped Lyman alpha (DLA) system at z = 3.04984 in the QSO SDSSJ1419+0829 has near-ideal properties for an accurate determination of the primordial abundance of deute…
A new candidate for probing Population III nucleosynthesis with carbon-enhanced damped Lyman-alpha systems
Ryan Cooke, Max Pettini, Michael Murphy
We report the identification of a very metal-poor damped Lyman-alpha system (DLA) at z_abs = 3.067295 that is modestly carbon-enhanced, with an iron abundance of ~1/700 solar ([Fe/…
