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财年获得的结果进行了相关的后续研究。具体来说，我和我的合作者从 HSC-SSP 第一年的数据中获得了新的簇透镜测量。然后，我对使用 SDSS 形状测量的 2021 财年结果与使用 HSC-SSP 形状测量的新结果进行了初步比较。初步结果表明，2021 财年的难题可以通过新的星团透镜测量来解决，并且今天正在进行进一步的研究和分析。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共享。这种重构使当前和未来有兴趣快速学习并能够执行分析的研究人员变得容易，特别是运行马尔可夫链蒙特卡罗模拟进行似然分析。上述两项成就将使这项资助的影响在其结束后持续很长时间。

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.
