Full-sky SZ maps and cluster catalog

This page contains full-sky maps of the kinematic and thermal Sunyaev-Zel'dovich signal. The different models are described in detail in our paper (Flender et al 2015, arXiv:1511.02843). We make the following data products available:<br>ksz_mod1_R13.fits - kSZ map, Model Iksz_mod2_R13.fits - kSZ map, Model IIksz_mod3_R13.fits - kSZ map, Model IIItsz150_R13.fits - tSZ map at 150Ghzcatalog_fullsky_zsm1.fits - full-sky halo catalog<br>All maps are provided in the form of full-sky Healpix maps in ring-ordering with nside=8192. The units in all maps are mikro-Kelvin, relative to the average CMB temperature. The halo catalog contains all halos identified with a friends-of-friends halo finder with more than 1000 particles. The catalog is in fits format with the following fits keys (all float, except HALO_ID, which is a long int):<br>RA - right ascension in degreesDEC - declination in degreesM200RED - M200c (defined with respect to the critical density) in units of Msun/hM200 - M200c in units of MsunM500RED - M500c in units of Msun/h (translated from M200RED, using the cM-relation from Bhattacharya et al. (2013))M500 - M500c in units of MsunREDSHIFT - redshift of the haloHALO_ID - identification number of the haloVLOS - comoving peculiar line-of-sight velocity of the halo, in km/sC200 - concentration assigned to the halo based on M200c, following the cM-relation from Bhattacharya et al. (2013)<br>---The Simulation---Our maps were generated from a simulation carried out with HACC (Habib et al. 2016). In this simulation, 3200³ particles were evolved in a (2.1Gpc)³ volume, leading to a mass resolution of ~10¹⁰Msun. The cosmology used is close to the best-fit WMAP-7 parameters. The simulation is part of a large suite of simulations, the so-called Titan-Mira Universe suite. More results from this simulation, including power spectra, mass functions, and concentration-mass relation measurements can be found in Heitmann et al. (2015).<br>---Publications---If you use our maps and catalogs, please cite our paper:Simulations of the Pairwise Kinematic Sunyaev-Zeldovich SignalS. Flender, L. Bleem, H. Finkel, S. Habib, K.

本页面包含动理学苏尼亚耶夫-泽尔多维奇（kinematic SZ, kSZ）与热学苏尼亚耶夫-泽尔多维奇（thermal SZ, tSZ）信号的全天域地图。相关不同模型的详细说明已发表于我们的研究论文（Flender等，2015，arXiv:1511.02843）。本次公开提供以下数据产品：
ksz_mod1_R13.fits —— 模型I的kSZ地图；ksz_mod2_R13.fits —— 模型II的kSZ地图；ksz_mod3_R13.fits —— 模型III的kSZ地图；tsz150_R13.fits —— 150GHz频段的tSZ地图；catalog_fullsky_zsm1.fits —— 全天域暗物质晕星表
所有地图均采用Healpix格式的全天域环序文件，分辨率参数nside=8192。所有地图的单位为微开尔文（μK），相对于宇宙微波背景（CMB）的平均温度。
该星表包含所有通过朋友-朋友（friends-of-friends, FoF）暗物质晕发现算法识别出的、包含超过1000个粒子的暗物质晕。星表采用FITS格式，包含以下关键字段（除HALO_ID为长整型外，其余字段均为浮点型）：
RA —— 赤经，单位为度；DEC —— 赤纬，单位为度；M200RED —— 以临界密度定义的M200c，单位为M☉/h；M200 —— 以临界密度定义的M200c，单位为M☉；M500RED —— 以临界密度定义的M500c，单位为M☉/h（由M200RED通过Bhattacharya等（2013）提出的浓度-质量（cM）关系转换得到）；M500 —— 以临界密度定义的M500c，单位为M☉；REDSHIFT —— 暗物质晕的红移；HALO_ID —— 暗物质晕的识别编号；VLOS —— 暗物质晕的共动视线方向特殊速度，单位为km/s；C200 —— 根据M200c，基于Bhattacharya等（2013）的浓度-质量关系赋予暗物质晕的浓度参数。
---模拟概况---
本数据集的地图由HACC模拟（Habib等，2016）生成。该模拟在体积为(2.1Gpc)³的计算域内演化了3200³个粒子，对应的质量分辨率约为10¹⁰M☉。模拟采用的宇宙学参数接近威尔金森微波各向异性探测器（WMAP）-7的最佳拟合结果。该模拟属于大型模拟套件“Titan-Mira Universe”的一部分。关于该模拟的更多研究结果，包括功率谱、质量函数以及浓度-质量关系测量结果，可参考Heitmann等（2015）的论文。
