The baryonic feedback effect is an important systematic error in the weak lensing (WL) analysis. It contributes partly to the S ₈ tension in the literature. With the next generations of large scale structure (LSS) and CMB experiments, the high signal-to-noise kinetic Sunyaev-Zel'dovich (kSZ) effect detection can tightly constrain the baryon distribution in and around dark matter halos, and quantify the baryonic effect in the weak lensing statistics. In this work, we apply the Fisher matrix technique to predict the future kSZ constraints on 3 kSZ-sensitive Baryon Correction Model (BCM) parameters. Our calculations show that, in combination with next generation LSS surveys, the 3rd generation CMB experiments such as AdvACT and Simon Observatory can constrain the matter power spectrum damping S(k) to the precision of σ _S (k) < 0.8%√(37.8 Gpc³h^-3-3/V) at k ≲ 10h/Mpc, where V is the overlapped survey volume between the future LSS and CMB surveys. For the 4th generation CMB surveys such as CMB-S4 and CMB-HD, the constraint will be enhanced to σ _S (k) < 0.4%√(37.8 Gpc³h^-3/V). If extra-observations, e.g. X-ray detection and thermal SZ observation, can effectively fix the gas density profile slope parameter δ, the constraint on S(k) will be further boosted to σ _S (k) < 0.3%√(37.8 Gpc³ h ^-3/V) and σ _S (k) < 0.1%√(37.8 Gpc³ h ^-3/V) for the 3rd and 4th generation CMB surveys.

未来动力学Sunyaev-Zel'dovich效应探测对重子反馈效应的预测约束


重子反馈效应是弱透镜（WL）分析中的一个重要系统误差。它在一定程度上造成了文献中的 S ₈ 张力。通过下一代大规模结构（LSS）和CMB实验，高信噪比动力学Sunyaev-Zel'dovich（kSZ）效应检测可以严格约束暗物质晕内部和周围的重子分布，并量化重子弱透镜统计中的效应。在这项工作中，我们应用 Fisher 矩阵技术来预测 3 个 kSZ 敏感重子校正模型 (BCM) 参数的未来 kSZ 约束。我们的计算表明，结合下一代LSS巡天，AdvACT和西蒙天文台等第三代CMB实验可以将物质功率谱阻尼S(k)约束到σ _S (k)的精度< 0.8%√(37.8 Gpc ³ h ^-3 -3/V) at k ≲ 10h/Mpc，其中 V 是未来 LSS 和 CMB 调查之间的重叠调查量。对于CMB-S4、CMB-HD等第四代CMB测量，约束将增强为σ _S (k) < 0.4%√(37.8 Gpc ³ h ^-3 /V）。如果额外观察，例如X射线探测和热SZ观测，可以有效地固定气体密度剖面斜率参数δ，对S(k)的约束将进一步提升到σ _S (k) < 0.3%√(37.8 Gpc ³ h ^-3 /V) 和 σ _S (k) < 0.1%√(37.8 Gpc ³ h ^-3
