I am Clayton Strawn, a graduate student working with Joel Primack at UCSC, and I am writing this email on behalf of myself, Santi, Joel, Ji-hoon, and all other co-authors of AGORA Paper VI: "CGM."</div><div><br></div><div>--</div><div>[1] Recent AGORA Efforts</div><div><br></div><div>As you are well aware, in the past 2 years the Collaboration has been working hard to analyze the cosmological zoom-in simulations of a MW-mass galaxy introduced in AGORA Paper III (“CosmoRun”; Roca-Fabrega et al. 2021). Since Paper III, we have been working on mainly three fronts: </div><div>- Paper IV (“CosmoRun2”): continue our comparison of CosmoRun at z~2 and below, while introducing AREPO to AGORA</div><div>- Paper V (“Satellites”): compare the satellite galaxy/halo populations at z~2, using 7 CosmoRuns and 7 counterpart DMO runs</div><div>- Paper VI (“CGM”): compare the circumgalactic medium at z~1 and z~3 among the simulations and with observations</div><div><br></div><div>[2] AGORA Paper “CGM” Beta Release</div><div><br></div><div>● We are pleased to announce that Paper VI “CGM” is ready for submission to the ApJ. The draft was signed off by all the co-authors and the AGORA Steering Committee. The main result of this work is that there is substantial difference between the codes in the CGM, mostly due to different generation and dispersion of metals from different feedback recipes, but with some effects of grid vs particle codes and other particularities as well. Regardless, we find that most codes have fairly low detected column densities in common ions, and most interestingly (figure 13) that different ions do not follow similar dynamical rules -- low ion column densities are mostly determined by the ion fraction along the line of sight, and fairly insensitive to metallicity of the individual code (which varies a lot), while high ions are mostly determined by the metallicity and all fall in roughly the same area in ion fraction. This result was made much more clear by the carefully calibrated process used in AGORA, as having vastly different galaxies or parameters would have obscured this result, as we talk about in the end of Section 3.4.</div><div><a href="https://drive.google.com/file/d/14s8ZdVMLXSYKz3A5JA_aR2Con6-b6sth/view?usp=drive_link" target="_blank">https://drive.google.com/file/d/14s8ZdVMLXSYKz3A5JA_aR2Con6-b6sth/view?usp=drive_link<br></a></div><div><br></div><div>● During the “beta release”, we would be happy to hear your last-minute comments and feedback by July 26 (Wed), although major changes to the manuscript may not be desired at this point, as the draft has been circulating among increasingly larger audiences for months. Please feel free to email any of your thoughts directly to Clayton, Santi, or Ji-hoon. We plan to submit the paper to the ApJ right afterwards. We thank you in advance for your valuable insights. </div><div><br></div><div>[3] Timeline for Papers IV to VI</div><div><br></div><div>● The Paper VI co-authors have agreed to first submit the paper to ApJ after the beta release, but *not* to the arXiv yet. While Paper VI moves through the referee process, Paper IV will be wrapped up by Santi Roca-Fabrega et al and submitted to ApJ *and* arXiv, at which point Paper VI will also be posted on the arXiv, alongside Paper V (Satellites), which is also already submitted and will hopefully be accepted during this time.</div><div><br></div><div>● You are welcomed to contribute to any other ongoing projects in AGORA (<a href="https://sites.google.com/site/projectagoraworkspace/collaborative-documents/progress-report-25" target="_blank">https://sites.google.com/site/projectagoraworkspace/collaborative-documents/progress-report-25</a>).
