This paper presents a study of the ISW effect from the Planck 2015 temperature and polarization data release. The CMB is cross-correlated with different LSS tracers: the NVSS, SDSS and WISE catalogues, and the Planck 2015 lensing map. This cross-correlation yields a detection at $4\,σ$, where most of the signal-to-noise is due to the Planck lensing and NVSS. In fact, the ISW effect is detected only from the Planck data (through the ISW-lensing bispectrum) at $\approx 3\,σ$, which is similar to the detection level achieved by combining the cross-correlation signal coming from all the catalogues. The ISW signal allow us to detect $Ω_Λ$ at more than $3\,σ$. This cross-correlation analysis is performed only with the Planck temperature data, since the polarization scales available in the 2015 release do not permit significant improvement of the CMB-LSS cross-correlation detectability. Nevertheless, polarization data is used to study the anomalously large ISW signal previously reported through the stacking of CMB features at the locations of known superstructures. We find that the current Planck polarization data do not exclude that this signal could be caused by the ISW effect. In addition, the stacking of the Planck lensing map on the locations of superstructures exhibits a positive cross-correlation with these large-scale structures. Finally, we have improved our previous reconstruction of the ISW temperature fluctuations by combining the information encoded in all the previously mentioned LSS tracers. In particular, we construct a map of the ISW secondary anisotropies and the corresponding uncertainties map, obtained from simulations. We also explore the reconstruction of the ISW anisotropies caused by the LSS traced by the 2MPZ survey by directly inverting the density field into the gravitational potential field.
Integrated Sachs Wolfe Effect and Rees Sciama Effect
自R. K. Sachs和A. M. Wolfe预言了宇宙微波背景(CMB)中各向异性的存在,并且自10年前首次观测到积分萨克斯-沃尔夫效应(ISW)以来。ISW效应为我们提供了一个独特的宇宙加速膨胀的探测器。大尺度结构与CMB之间的互相关是从数据中提取ISW效应的最有前途的方法。在这篇文章中,我们回顾了ISW效应的物理学,并总结了最近的观测结果和解释。
Impact of a causal primordial magnetic field on the Sachs Wolfe Effect
我们提出了一个分析推导的萨克斯沃尔夫效应的原始磁场,产生的因果过程,如一阶相变在早期宇宙。至于拓扑缺陷的情况下,我们应用广义相对论结的条件,以匹配的扰动变量之前和之后的相变,在这样的方式,总能量动量张量是保守的过渡。我们发现,相关的贡献,磁萨克斯-沃尔夫效应来自次领先的大尺度极限的度量扰动。由于自由流中微子的存在,导致序项被强烈抑制。我们导出了中微子补偿效应,并证实了由因果磁场产生的磁性SachsWolfe谱的性质与最近的数值分析结果一致,为l(l+1)C_l^B ~ l ^2。

The Integrated Sachs-Wolfe Signal from BOSS Super-Structures
宇宙结构通过综合的萨克斯-沃尔夫效应在微波背景辐射上留下印记。我们使用SDSS-III重子声学振荡巡天在红移0.43 < z < 0.65处构造了线性信号的模板图。我们在97%的置信水平下验证了这张图在普朗克CMB温度图上的印记,并与密度-温度互相关测量结果一致。使用这个ISW重建作为模板,我们调查的存在下,ISW源,并进一步研究的Granett-Neyrinck-Szapudi超空和超星系团目录的属性。我们首次对这些结构的三维密度分布进行了研究,并证明它们是重要的结构。模型拟合表明,超空是沿着视线拉长,我们建议,这种特殊的取向可以挑选出来的光度红移空间中的空洞发现算法。我们从公开的空洞和星团星表中测量了普朗克图中的平均温度分布。在试图最大限度地堆叠ISW信号,我们构建了一个新的目录的超级结构的基础上,当地的高峰和低谷的引力势。然而,我们没有发现这些结构和CMB温度之间的显着相关性。
在本文中,我们依靠的类星体(QSO)的斯隆数字巡天数据发布六(SDSS DR 6)的约100万光度选择类星体的目录计算积分萨克斯-沃尔夫(ISW)效应在高红移,旨在约束的行为的膨胀率,从而在这些时期的暗能量的行为。这个独特的样本显着扩展了以前的目录,以更高的红移,同时保持高效率的选择算法。我们计算了类星体数密度的自关联函数(ACF),从中提取了偏差和恒星污染。然后我们计算了不同子样本中类星体数密度和宇宙微波背景(CMB)温度涨落之间的互相关联函数(CCF):在高z>1.5和低z<1.5的红移下,对两种不同的类星体选择进行了保守和更投机的分析。我们发现了在2.7σ水平上不为零的互相关性的总体证据,而该证据在z>1.5时下降到1.5σ。我们专注于ISW的能力,以约束在高红移的暗能量分量的行为在\LambdaCDM和早期的暗能量宇宙学,当暗能量基本上不受观测。目前,包括ISW数据的结果在一个穷人的改善相比,从其他宇宙学数据集获得的约束。我们研究了未来高红移类星体巡天的能力,发现ISW信号可以改善普朗克CMB数据中最重要的宇宙学参数的约束,包括高红移暗能量丰度,改善因子为\sim 1.5。
CMB temperature anisotropy at large scales induced by a causal primordial magnetic field
我们提出了一个由原始磁场的萨克斯沃尔夫效应的解析推导。为了一致地指定初始条件,我们假设磁场是由因果过程产生的,即在早期宇宙中的一阶相变。对于拓扑缺陷的情况,我们应用广义相对论结条件来匹配产生磁场的相变之前和之后的微扰变量,以这样的方式,总能量动量张量在整个过渡中守恒,并且满足爱因斯坦方程。我们进一步解析地求解了包含中微子的大尺度下的度规和流体扰动的演化方程,并导出了磁性Sachs Wolfe效应。我们发现,相关的贡献,磁萨克斯-沃尔夫效应来自次领先的大尺度极限的度量扰动。事实上,由于自由流中微子的存在,首阶项被强烈抑制。我们动态地导出了中微子补偿效应,证实了由因果磁场产生的磁性SachsWolfe谱的性质为l(l+1)C_l^B \propto l ^2,这与最近的数值分析结果一致。
