项目摘要
This research will develop theoretical frameworks and analysis tools for the tremendous outpouring of Cosmic Microwave Background (CMB) and Large Scale Structure (LSS) and galaxy formation data that will arise over 2019-2024 period, and beyond. The 2012-18 period has been amazing, solidifying a Standard Model of Cosmology (SMc) dominated by dark energy and dark matter at high precision, in large part through our activities on the Planck CMB satellite team and the higher resolution Atacama Cosmology Telescope (ACT) team. The impact was recently recognized by the 2018 Gruber Prize in Cosmology to our Planck group for providing "the definitive description of the universe on the largest and smallest scales." CMB and LSS: This proposal emphasizes planned work on Advanced ACTPol and the Simons Observatory follow-on, the related CCATprime telescope, a second flight of the balloon-borne Spider experiment, cross-correlation work of the CMB with the LSS space experiment Euclid and other ground-based LSS surveys, and various three-dimensional line intensity mapping (LIM) experiments probing galaxy formation and assembly. A primary motivation is to find new physics beyond the standard model of cosmology (BSMc). BSMc projects include how to measure whether dark energy is coupled to matter, whether quantum aspects of dark matter are observable, and to create statistical tests for novel non-Gaussian primordial structures generated in the early Universe. Gravity Waves and Interstellar Dust Polarization: A major CMB target is to discover early-Universe gravity waves with CMB polarization. The greatest challenge is separating polarized Galactic emissions from what is truly primordial. For this we are developing novel re-mapping measures of anisotropy in the "Milky Way's interstellar web" polarized emissions. Line Intensity Mapping is an emerging technique to map large cosmological volumes to probe the Epoch of Galaxy Assembly and even of the pre-galactic cosmic dawn. The Canadian CHIME radio telescope targeting the 21cm line of hydrogen and COMAP in California, targeting a carbon monoxide line, are now taking data, and CCATprime, targeting ionized carbon, is under construction. Our group at CITA is engaging in all of the analytical and theoretical challenges that will arise from these vast new data sources, including any new BSMc physics that might emerge. Theory and Simulations: We will create ensembles of rapidly-computable yet accurate SMc and BSMc mock simulations we call webskys for cross-analyses, since all of these big-sky experiments are entangled in one fully correlated light-cone, and must ultimately be analyzed together. This is a challenge because of complex gas processes, but the webskys we construct will learn from the highest resolution gasdynamical feedback simulations. HQP: Such work has been and is well suited for engagement of HQP locally at all levels at CITA: Senior RAs and postdocs, graduate and undergraduate research students.
这项研究将为2019-2024年及以后大量涌现的宇宙微波背景(CMB)和大尺度结构(LSS)以及星系形成数据开发理论框架和分析工具。2012年至2018年期间是惊人的,巩固了由暗能量和暗物质主导的宇宙学标准模型(SMc),在很大程度上是通过我们在普朗克CMB卫星团队和更高分辨率的阿塔卡玛宇宙望远镜(ACT)团队的活动。最近,2018年格鲁伯宇宙学奖向我们的普朗克小组承认了这一影响,因为它提供了“最大和最小尺度上宇宙的明确描述”。“资本市场管理局和地方安全局:该建议强调计划中的高级ACTPol和西蒙斯天文台后续工作、相关的CCATprime望远镜、气球载蜘蛛实验的第二次飞行、CMB与LSS空间实验欧几里得和其他地面LSS测量的互相关工作,以及探测星系形成和集合的各种三维线强度绘图实验。一个主要的动机是发现超越宇宙学标准模型(BSMc)的新物理。BSMc项目包括如何测量暗能量是否与物质耦合,暗物质的量子方面是否可观测,以及为早期宇宙中产生的新的非高斯原始结构创建统计测试。重力波和星际尘埃极化:CMB的一个主要目标是发现具有CMB极化的早期宇宙重力波。最大的挑战是将极化的银河辐射与真正的原始辐射分开。为此,我们正在开发新的重新映射措施的各向异性在“银河系的星际网络”偏振发射。 线强度测绘是一种新兴的技术,可以绘制大的宇宙学体积,以探测星系集合时代甚至前银河宇宙黎明。位于加州的加拿大CHIME射电望远镜瞄准氢的21厘米谱线,COMAP瞄准一氧化碳谱线,目前正在采集数据,而CCATprime瞄准电离碳,目前正在建造中。我们在CITA的团队正在参与这些庞大的新数据源所带来的所有分析和理论挑战,包括可能出现的任何新的BSMc物理。 理论与模拟:我们将创建快速计算但准确的SMc和BSMc模拟模拟的集合,我们称之为webskys用于交叉分析,因为所有这些大天空实验都纠缠在一个完全相关的光锥中,最终必须一起分析。由于复杂的气体过程,这是一个挑战,但我们构建的webskys将从最高分辨率的气体动力学反馈模拟中学习。 HQP:这些工作一直非常适合CITA当地各级HQP的参与:高级RA和博士后,研究生和本科生研究生。
