Stacked CMB lensing and ISW signals around superstructures in the DESI Legacy Survey

The imprints of large-scale structures on the Cosmic Microwave Background can be studied via the CMB lensing and Integrated Sachs-Wolfe (ISW) signals, which are important cosmological probes. In particular, the stacked ISW signal around supervoids with extreme diameters has been claimed in several works to be anomalously high. In this study, we use four tomographic redshift bins with $0
