Over the past 35 years (!) my group has shown that primary cosmic background radiation (CMB) anisotropies are the key observables for elucidating the correct structure formation theory, and precision values of cosmological parameters that define it, such as the dark energy, dark matter, baryon and neutrino densities, the amplitude and slope of the spectrum of primordial fluctuations, including gravity waves, the average spatial curvature of the Universe, early and late inflation constraints, including on primordial non-Gaussianities in the spatial curvature. I have been involved in Planck since 1993, as a Planck coI and Canadian Space Agency PI since 2001. Analyzing our Planck results has been my primary focus over the past grant cycle, with major releases of data products and results in 2011, 2013 and 2015, and more work for the next 2017 releases, and beyond): our Canadian group has had a major impact on the cornucopia of influential Planck papers covering all of the cosmological topics listed above. Our Chile-based Atacama CMB Cosmology telescope extended the results to higher resolution. Over the next five years the outpouring of cosmic data will greatly enhance, from CMB and large scale structure (LSS) and other probes, including much more from secondary CMB anisotropies involving nonlinear physics. My group will be in the thick of it, as team members on LSS surveys (the redshifted-21cm BAO experiment CHIME, carbon monoxide and CII intensity mapping experiments, ESA’s EUCLID), as well as CMB experiments (the balloon-borne Spider, since 2005, Advanced ACTpol followed by the Simons Observatory and then the ambitious DOE-based CMB Stage 4).

在过去的35年里（！）我的小组已经表明，初级宇宙背景辐射（CMB）各向异性是阐明正确的结构形成理论的关键观测量，以及定义它的宇宙学参数的精确值，如暗能量、暗物质、重子和中微子密度、原始波动谱的振幅和斜率，包括重力波、宇宙的平均空间曲率，早期和晚期的膨胀约束，包括对空间曲率中原始非高斯性的约束。自1993年以来，我一直参与普朗克研究，自2001年以来，我是普朗克研究所和加拿大航天局的PI。在过去的资助周期中，分析我们的普朗克结果一直是我的主要关注点，2011年，2013年和2015年发布了主要的数据产品和结果，并在接下来的2017年及以后发布了更多的工作：我们的加拿大小组对涵盖上述所有宇宙学主题的有影响力的普朗克论文的聚宝盆产生了重大影响。我们位于智利的阿塔卡马CMB宇宙学望远镜将结果扩展到更高的分辨率。在接下来的五年里，来自CMB和大尺度结构（LSS）以及其他探测器的宇宙数据将大大增加，包括更多来自涉及非线性物理的次级CMB各向异性的数据。我的小组将在它的厚，作为团队成员的LSS调查（红移-21厘米BAO实验CHIME，一氧化碳和CII强度映射实验，欧空局的欧几里得），以及CMB实验（气球载蜘蛛，自2005年以来，先进的ACTpol，其次是西蒙斯天文台，然后是雄心勃勃的能源部的CMB阶段4）。
