Cosmic Dawn Science: COPAG Science Interest Group #3

Cosmic Dawn

We have learned much in recent years about the history of the universe, from the big bang to the present day. A great mystery now confronts us: When and how did the first galaxies form out of cold clumps of hydrogen gas and start to shine---when was our "cosmic dawn"? (New Worlds, New Horizons)

This Science Interest Group, chartered under the Cosmic Origins Program Analysis Group (COPAG), focusses on the science cases, observations, and technology development needed to address this "great mystery" of Cosmic Origins.


The second meeting for the Cosmic Dawn SIG will be held on 2017 January 3, just prior to the 229th AAS meeting. Given recent focus on new missions, including Probe-class missions, and the opportunity of the COPAG community to suggest new technology for NASA, this meeting will focus on current and future technology development for Cosmic Dawn missions. The agenda is now available. Please consult the agenda, as the logistics for this meeting are different than for more AAS meetings.

The initial meeting for the Cosmic Dawn SIG was held on 2016 January 4, just prior to the 227th AAS meeting. This "kickoff" meeting was designed to survey the landscape of current and potential future approaches to studying Cosmic Dawn. The agenda and presentations are now available.

Paul Hertz (NASA Astrophysics) has begun a conversation with the community regarding potential Probe-class missions, which would receive more funding than Explorer missions but not as much as a Flagship or Large mission. (An oft-stated cost cap for a Probe is < $1B.) The COPAG has requested white papers on potential Probe concepts. Individuals with concepts related to exploring Cosmic Dawn are encouraged to submit a white paper!


Membership is open to all. In order to be added to the mailing list, please contact Joseph Lazio (Joseph [dot] Lazio [at] jpl [dot] nasa [dot] gov).
