标题： Baryon Pasting the Uchuu Lightcone Simulation

摘要： 我们展示了从半球Uchuu光锥模拟中推导出的重子粘贴（BP）X射线和热Sunyaev-Zel'dovich（tSZ）图。 这些BP-Uchuu地图是使用超过$75$百万个质量在$M_{500c} \geq 10^{13} M_\odot$范围内的暗物质晕构建的，红移范围为$0 \leq z \leq 2$。 我们BP-Uchuu光锥地图的一个显著特征是它们能够在地图级别评估由三轴气体晕和内部气体特性分别引起的外在和内在散射的影响。 我们表明，三轴气体导致了集群和群组X射线亮度的显著散射，占核心切除测量总散射的一半左右。 此外，晕的热压和气体密度剖面中的散射增强了X射线和SZ功率谱，导致宇宙参数估计出现偏差。 由于BP-Uchuu地图具有广泛的天空覆盖和大量的晕样本，这些发现统计上是稳健的。 BP-Uchuu地图可在 https://app.globus.org/file-manager?origin_id=cf8dadb7-b6e9-4e2c-abc1-0813877efc13 公开获取。 显示英文摘要

摘要： We present the Baryon Pasted (BP) X-ray and thermal Sunyaev-Zel'dovich (tSZ) maps derived from the half-sky Uchuu Lightcone simulation. These BP-Uchuu maps are constructed using more than $75$ million dark matter halos with masses $M_{500c} \geq 10^{13} M_\odot$ within the redshift range $0 \leq z \leq 2$. A distinctive feature of our BP-Uchuu Lightcone maps is their capability to assess the influence of both extrinsic and intrinsic scatter caused by triaxial gaseous halos and internal gas characteristics, respectively, at the map level. We show that triaxial gas drives substantial scatter in X-ray luminosities of clusters and groups, accounting for nearly half of the total scatter in core-excised measurements. Additionally, scatter in the thermal pressure and gas density profiles of halos enhances the X-ray and SZ power spectra, leading to biases in cosmological parameter estimates. These findings are statistically robust due to the extensive sky coverage and large halo sample in the BP-Uchuu maps. The BP-Uchuu maps are publicly available on https://app.globus.org/file-manager?origin_id=cf8dadb7-b6e9-4e2c-abc1-0813877efc13 .
