We investigate how 3D cosmic shear can constrain a class of cosmological models in which both the matter-dominated epoch of the evolution of the Universe and its current, accelerated expansion can be driven by a single, exotic scalar field with a non-canonical kinetic term in its Lagrangian, which behaves both as Dark Matter (DM) and Dark Energy (DE).

Abstract

We investigate how 3D cosmic shear can constrain a class of cosmological models in which both the matter-dominated epoch of the evolution of the Universe and its current, accelerated expansion can be driven by a single, exotic scalar field with a non-canonical kinetic term in its Lagrangian, which behaves both as Dark Matter (DM) and Dark Energy (DE).
