Probing Anisotropies of SGWB with LISA

This lecture explores the sensitivity of the Laser Interferometer Space Antenna (LISA) to anisotropies in the Stochastic Gravitational Wave Background (SGWB). The analysis includes the main sources of SGWB, the Signal-to-Noise estimator, and the detectability of anisotropic features with LISA. The study focuses on astrophysical and cosmological sources, noise angular spectrum, and the implications of anisotropies in understanding the origin of SGWB. The lecture also covers the potential of LISA in detecting signals from unresolved sources like merging binary black holes, inspiraling binary systems, and more. Various models and constraints related to GW energy density are discussed.
