Large-scale dynamos driven by shear-flow-induced jets are a fascinating phenomenon in astrophysics, offering insights into the generation of magnetic fields in various celestial bodies. This article explores the mechanisms behind these dynamos, drawing from a diverse range of studies. The references provided offer a comprehensive view of the topic, covering various aspects such as hydromagnetic dynamo models, the effects of rapid distortion, and the suppression of turbulence by sheared flow. Additionally, the article delves into the role of shear-driven dynamo waves, the generation of large-scale magnetic fields by small-scale dynamos in shear flows, and the influence of sheared poloidal rotation on edge turbulence. The studies also examine the dynamics of stratified horizontal shear flows at low Péclet numbers, the role of vorticity and magnetic dynamo from subsonic expansion waves, and the impact of velocity shear and rotating convection on large-scale dynamo action. Furthermore, the article discusses the generation of magnetic fields by combined action of turbulence and shear, mean magnetic field generation in sheared rotators, and the cross-helicity effect in young galaxies. The references also touch on helioseismic properties of dynamo waves, the solar cycle, and the case for a distributed solar dynamo shaped by near-surface shear.
