Gradient Ricci expanding solitons are immortal self-similarities to the Ricci flow. We will focus on the possibility of resolving metric cones over a smooth compact manifold by such expanders. More precisely, we will start by giving examples confirming these expectations then we will concentrate on asymptotic estimates, compactness phenomena, and deformations of conical Ricci expanders.
