III: Calibration and Comparison of Cosmological Zoom-in Simulations using Seven Different Numerical Codes<br class=""><br class="">ABSTRACT: <div class="">In this talk, we will present the latest results from the AGORA collaboration. In this new work, which is the result of four years of research, we present a suite of high-resolution cosmological zoom-in simulations to z=4 of a MW-mass halo obtained using seven contemporary astrophysical simulation codes widely used in the numerical galaxy formation community. As a first result, we introduce a series of four calibration steps each of which is designed to reduce the number of tunable simulation parameters adopted in the final cosmological run. These steps can now be used by non-participating code groups to obtain equivalent models and to join the many follow-up projects we started. After completing these calibration steps, we reach a suite of cosmological simulations with similar mass assembly histories down to z=4. We show that with numerical accuracy that resolves the internal structure of a target halo, the codes overall agree well with one another, although showing differences in the most SNe feedback-dependent parameters. We argue that, if adequately tested following our proposed calibration steps and common parameters, code groups around the world can use this new suite of high-resolution cosmological zoom-in simulations to test and validate their codes and sub-grid physics. Models obtained by the new code groups will be added to the suite and will enrich future comparison projects. <br class="">Currently, the seven code groups are running their models down to z=2, and below, and they are saving a large number of snapshots. This large amount of data will allow us to continue with the ongoing science-oriented projects. We will show the first results obtained of two of these new projects. In the next months, we will make data from each of the calibration steps, and the final run down to z=4, publicly available. We encourage new code groups to use this data and join the collaboration by adopting the common initial conditions, the common easy-to-implement physics package, and the proposed calibration steps. We can provide them with early access to the data, and with technical support. We will end this talk by announcing the dates of the next AGORA workshop and presenting the new AGORA project webpage (<a href="http://www.agorasimulations.org/" class="">www.agorasimulations.org</a>).<br class=""><blockquote type="cite" class=""><blockquote type="cite" cite="mid:EADB6968-C2A4-40D2-82D5-D0EC521328C2@snu.ac.kr" class=""><blockquote type="cite" class=""><blockquote type="cite" cite="mid:9C92517F-88B6-46C9-A9DD-F54D0962AEBD@ucsc.edu" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""><blockquote type="cite" class=""></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></blockquote>====================================================================================================<br class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div></div></div></div><div class="">
