Abstract: We study the geometries originated by adding D5-branes intersecting D3-branes along a 2+1 dimensional subspace, considering the backreaction of the D5s. We construct the configuration realizing the addition of both massless and massive flavors at zero T and generalize the results of massless fundamentals to the case of having a non zero T field theory dual. We explore the properties of these backgrounds by computing several observables, such as Wilson loops, entanglement entropies or studying the hydrodynamics. By considering a more generic brane profile which vanishes in the UV we can also construct solutions with two possible behaviours in the IR: an isotropic fixed point or a geometry with anisotropic Lifshitz like scaling symmetry.
