A lower density universe? - Measuring imprints of large scale structure on the CMB
Event Start:
2021-02-08T15:00:00
Event End:
2021-02-08T16:00:00
Event Information:
Large-scale structures (LSS) can leave various imprints on the cosmic microwave background(CMB). Two main features come from the spatial and temporal perturbations of the CMB photon trajectory due to LSS: weak lensing and the integrated Sachs-Wolfe effect. I will give a summary of our paper "Galaxy clustering in Legacy Survey and its imprint on the CMB" (arXiv: 2010.00466), where we use the DESI Legacy Imaging Survey to extract cosmological information from the above effects in the redshift range 0<z<0.8.
