Weak-lensing studies via cosmic voids are a promising probe of modified gravity (MG). The excess surface mass density (ESD) is widely used as a lensing statistic in weak-lensing research. In this paper. we use the ray-tracing method to study the ESD around voids in simulations based on cubic Galileon (CG) gravity. https://editsbloomchices.shop/product-category/socks/
