• #### 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 ...
