The Cosmological Radiative Transfer Comparison Project (CRTCP) was organized several years ago to guide and promote progress on the new frontier in computational cosmology, incorporating radiation transport algorithms in the simulation of cosmic structure formation and evolution. We focused first on the transfer of ionizing radiation, to account for the radiative feedback associated with galaxy and star formation, including that responsible for cosmic reionization. Toward this end, we gathered representatives of the various groups and individuals who were developing different algorithms and codes, to test and compare their different approaches by applying them to solve a common set of problems. Three previous workshops have now been organized, resulting in the first two CRTCP journal articles and a website for archiving initial conditions and results, to make it possible to test future codes against the same problems.

Now that four years have passed since CRTCP Workshop III, December 2008, the next (and long-overdue) workshop will take place on Dec. 12 - 14, 2012, once again on the campus of The University of Texas at Austin, hosted by Paul Shapiro. Much progress has been made in these last four years, and there are new challenges to discuss and tests and comparisons to be made. This will be an occasion to present our current research related to radiative transfer in cosmology, with a focus on numerical methodology, and to discuss and plan the future directions of the Comparison Project. We anticipate that this will lead to a new round of test problems and their publication.

As usual, everyone is welcome to attend, but at this point we ask you to CONFIRM your attendance by registering at the link below, since we need an accurate count to plan things accordingly.
