标题： Toward the first cosmological results of the NIKA2 Sunyaev-Zeldovich Large Program: The SZ-Mass scaling relation

摘要： 在Sunyaev-Zeldovich（SZ）宇宙学中，为了能够利用毫米波段的大规模巡天数据，需要两种工具：一方面需要对星系团内介质（ICM）的压力分布做出精确描述；另一方面需要与星系团质量相关的亮度-质量关系的标度关系。NIKA2相机工作在150和260 GHz频段，凭借其高角分辨率和大视场，非常适合用于精确的星系团SZ成像。NIKA2合作项目的SZ大计划（LPSZ）旨在观测一个由38个中间到高红移SZ选择的星系团样本，并同时使用SZ和X射线进行观测。目前的状态是所有LPSZ星系团都已完成观测，最终结果的分析正在进行中。我们详细介绍了NIKA2-LPSZ如何获得稳健的SZ-质量标度关系估计值以及如何将其用于获取宇宙学限制。 显示英文摘要

摘要： In Sunyaev-Zeldovich (SZ) cluster cosmology, two tools are needed to be able to exploit data from large scale surveys in the millimeter-wave domain. An accurate description of the IntraCluster Medium (ICM) pressure profile is needed along with the scaling relation connecting the SZ brightness to the mass. With its high angular resolution and large field of view, The NIKA2 camera, operating at 150 and 260 GHz, is perfectly suited for precise cluster SZ mapping. The SZ Large Program (LPSZ) of the NIKA2 collaboration is dedicated to the observation of a sample of 38 SZ-selected clusters at intermediate to high redshift and observed both in SZ and X-ray. The current status is that all LPSZ clusters have been observed and the analysis toward the final results is ongoing. We present in detail how NIKA2-LPSZ will obtain a robust estimation of the SZ-Mass scaling relation and how it will be used to obtain cosmological constraints.
