摘要:

本文从普朗克2015年公布的温度和偏振数据中研究了ISW效应。CMB与不同的LSS示踪剂相互关联:NVSS,SDSS和WISE目录,以及普朗克2015年透镜图。这种互相关产生在$4\,σ$的检测,其中大部分信噪比是由于普朗克透镜和NVSS。事实上,ISW效应仅从$\approx 3\,σ$处的普朗克数据(通过ISW透镜双谱)检测到,这类似于通过组合来自所有星表的互相关信号所实现的检测水平。ISW信号允许我们在超过$3\,σ$的情况下检测$Ω_Λ$。由于2015年版本中可用的偏振尺度不允许CMB-LSS互相关可探测性的显着改善,因此仅使用普朗克温度数据进行互相关分析。尽管如此,偏振数据被用来研究先前报道的通过在已知的上层建筑的位置处的CMB特征的堆叠的异常大的ISW信号。我们发现,目前的普朗克极化数据并不排除这种信号可能是由ISW效应。此外,普朗克透镜映射在超结构位置上的叠加表现出与这些大尺度结构的正互相关。最后,我们改进了我们以前的重建的ISW温度波动的信息编码在所有前面提到的LSS示踪剂相结合。特别是,我们构建了一个地图的ISW二次各向异性和相应的不确定性地图,从模拟中获得。我们还探讨了由2 MPZ调查追踪的LSS引起的ISW各向异性的重建,通过直接将密度场反演为重力位场。

英文摘要:

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.
