<div dir="ltr"><div dir="ltr"><div><font color="#000000">Dear AGORA colleague,</font></div><div><font color="#000000"><br></font></div><div><font color="#000000">I’m Hyeonyong Kim, a Ph.D student working with Ji-hoon Kim at Seoul National University. With the help and guidance of the AGORA collaboration, I have led the 10th AGORA paper, "High-z Run", and now I'm pleased to announce that the AGORA Paper X "High-z Run" is almost ready for submission to ApJ. Building upon the methodology and subgrid physics calibrated in the “CosmoRun" project (z=4), "AGORA High-z Run" aims to examine whether the physical models that successfully reproduce low-redshift galaxies across different codes can also explain the bright galaxy populations recently observed by JWST (z>10). In this paper, we demonstrate that even a “vanilla” galaxy formation model can reasonably reproduce the stellar mass, metallicity, and UV luminosity of JWST observations at z < 12, although discrepancies remain at the most extreme redshifts (z ~ 14). We also would like to share that, taking this as a foundation, we plan to carry out an AGORA High-res High-z Run to explore high-redshift galaxy formation with improved resolution and more refined subgrid physics.</font></div><div><font color="#000000"><br></font></div><div><font color="#000000">This version incorporates valuable feedback from code leaders and collaborators and may undergo minor revisions before submission, following additional comments from co-authors and members of the Steering Committee. During this “beta release” phase, we would greatly appreciate any final comments or suggestions by<b> Nov 5 (Wed)</b>. While major revisions are not expected at this stage, as the draft has already circulated among increasingly broader audiences in the past few weeks/months, we still welcome your insights. Please feel free to share your thoughts directly with any of the corresponding authors. We sincerely thank you in advance for your time and valuable feedback.</font></div><div><font color="#000000"><br></font></div><div><font color="#000000">You can find the latest version of the paper here [<a href="https://www.dropbox.com/scl/fi/grutj7eke5r7mz88vvh6x/AGORA_High-z_Beta.pdf?rlkey=6oe83030wvrhrzgzc6yof3mtu&st=eieox3sc&dl=0" target="_blank">link</a>].</font></div><span><font color="#000000"><div><br></div><div>Once again, thank you very much for your continuous effort in the AGORA collaboration!</div><div><br></div><div>Sincerely,</div><div>Hyeonyong, Ji-hoon, Minyong, and Santi, on behalf of the co-authors of AGORA Paper X</div></font></span></div>
