Recombination in the Early Universe

This research field is the one in which Professor Seager’s career started and it has seen a resurgence with the upcoming launch of ESA’s Planck Space Telescope. Prof. Seager is no longer actively working in this field of research.  Prof. Seager’s major contribution to recombination in the early Universe is in the form of two papers:

• A summary paper:
  Seager, S., Sasselov, D. D., & Scott, D. 1999, “A New Calculation of the Recombination Epoch”, 1999, ApJ, 523, L1-5.
• Full description:
  Seager, S., Sasselov, D. D., & Scott, D. 2000, “How Exactly Did the Universe Become Neutral?”, ApJS, 128, 407-430.
