COPAG Splinter Session at 233rd AAS Meeting

14 August 2018

Shedding Light on the End of Dark Ages: Defining an Enlightening Roadmap

Over the past decade there has been considerable activity within the community to understand how the first stars and galaxies formed, and how they shaped the initial structure of the Universe through reionization. The COPAG is interested in developing a strategic plan to address the best techniques, facilities, and data to address this foundation science element, since it has featured prominently in the science drivers for ongoing mission concept studies such as LUVOIR, HabEx, Lynx, and OST.

The COPAG will hold a splinter session at the Winter AAS in Seattle to shape how such a plan should be defined and what goals it should set. Please plan on joining us to do this. If you would be interested in participating please send a note to Susan Neff (Susan.G.Neff@nasa.gov) to let us know.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
