报告摘要:

Observations for the Cosmic Microwave Background (CMB) from WMAP and Planck have provided key information about our Universe at its initial stage. Large-scale structures in the late-time Universe interact via gravity and electromagnetism with CMB photons, causing additional temperature fluctuations. These secondary effects (e.g. gravitational lensing, Integrated Sachs-Wolfe effect, Sunyaev-Zeldovich effect) imprinted on the CMB provide invaluable information about our late-time Universe. I will summarise our attempts to advance our understanding about our physical Universe by exploiting the cross-correlations between large-scale structure and the CMB.
