Meeting+Announcement

The 21-cm background during, prior to, and after the epoch of reionization will soon be a major focus of low-frequency radio experiments. This workshop will address the cosmological and astrophysical information content of the 21-cm background, the 21-cm signal as a probe of the reionization history and of “first light” and galaxy formation, future directions and goals in the field both from ground and, and upcoming novel opportunities involving the 21-cm background in combination with other cosmological probes such as the CMB and cosmic shear. The workshop will encompass all aspects of the 21-cm background from theory to experimental concept studies.

This three-week workshop aims to bring together the theorists studying these problems with the observers and instrumentalists designing and building these experiments. We will discuss issues ranging from the fundamental processes of galaxy formation to the data processing essential to interpreting these results to the design and planning of future measurements.

The workshop itself will span three weeks, and attendees are strongly encouraged to visit for as long as possible. Attendance will be limited to 25-30 participants in order to facilitate informal interactions; we therefore strongly encourage participants to apply early. Formal talks will be limited, with ample time for collaboration and discussion.

Workshop Format
Aspen summer workshops are intended to "serve as focal points on topics of current interest. Workshops are very informal, with an extremely limited number of talks so that participants have ample time for informal discussion and to initiate new work." This workshop will follow the established format for Aspen summer workshops with only three formal sessions, each lasting only a few hours, per week. The rest of the time is available for informal interactions.
