Towards the First HSC-SSP Cluster Cosmology Results: Focus on Robustness against Projection Effects

在2022财年(2022年5月至2022年9月)，我对2021财年取得的成果进行了跟踪研究。具体地说，我和我的合作者从HSC-SSP的第一年数据中获得了一个新的星团透镜测量。然后，我对使用SDSS形状测量的2021财年结果和使用HSC-SSP形状测量的新结果进行了初步比较。初步结果表明，2021财年的谜题可能会通过新的星团透镜测量得到解决，目前进一步的研究和分析正在进行中。我还重构了星团宇宙学分析管道的代码库，并将其作为私人GitHub存储库与我的合作者分享。这种重构使当前和未来有兴趣做出贡献的研究人员能够轻松地快速学习并能够执行分析，特别是运行用于可能性分析的MarkovChain蒙特卡罗模拟。上述两项成果都将使这笔赠款的影响在其结束后长期存在。

In FY2022 (May 2022 to September 2022), I have carried out follow-up research related to the results obtained inFY2021. Specifically, my collaborators and I have obtained a new cluster lensing measurement from the HSC-SSPfirst-year data. I have then performed preliminary comparisons between the FY2021 results, using SDSS shapemeasurements, and new results using the HSC-SSP shape measurements. Preliminary results suggest that thepuzzles from FY2021 may be solved with the new cluster lensing measurements, and further studies and analysesare ongoing today.I have also refactored the codebase for the cluster cosmology analysis pipeline and have shared it with mycollaborators as a private github repository. This refactoring has made it easy for current and future researchersinterested in contributing to quickly learn and become able to perform the analysis, in particular the running of MarkovChain Monte Carlo simulations for likelihood analyses.Both of the above achievements will allow the impact of this grant to last long after its end.
