Cosmological Recombination of Lithium and Its Effect on the Microwave Background Anisotropies
(IOP Publishing, 2002)The cosmological recombination history of lithium, produced during big bang nucleosynthesis, is presented using updated chemistry and cosmological parameters consistent with recent cosmic microwave background (CMB) ... -
The Highly Deuterated Chemistry of the Early Universe
(IOP Publishing, 2011)A comprehensive chemistry of the highly deuterated species D2, D+ 2, D2H+, and D+ 3 in the early universe is presented. Fractional abundances for each are calculated as a function of redshift z in the recombination era. ... -
Resonant H – Photodetachment: Enhanced Photodestruction and Consequences for Radiative Feedback
(IOP Publishing, 2010)The hydrogen negative ion plays a crucial role in the formation of hydrogen molecules in the early universe. Cooling through excitation of \(H_2\) drives the formation of the first cosmological objects. The \(H_2\) molecules ... -
SPT-CL J0205–5829: A z = 1.32 Evolved Massive Galaxy Cluster in the South Pole Telescope Sunyaev-Zel'dovich Effect Survey
(American Astronomical Society / IOP Publishing, 2013)The galaxy cluster SPT-CL J0205–5829 currently has the highest spectroscopically confirmed redshift, z = 1.322, in the South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) survey. XMM-Newton observations measure a core-excluded ...
