Active galactic nuclei feedback drives structure formation in the universe, imparting cosmological consequences by supermassive black holes. Typically this feedback acts locally, arising from the prodigious luminosity of quasars or mechanical power of jets. However, it has become apparent that non-local feedback may also occur on cosmological scales via a chain of events that begins with the very-high energy gamma-ray emission of blazars and ends with the heating of the low-density intergalactic medium, increasing its temperature by more than an order of magnitude. The viability of this mechanism depends critically on the nonlinear development of beam-plasma instabilities driven by the propagating very-high energy gamma rays; the observational impact requires large-scale cosmological simulations of the Lyman-alpha forest and the formation of dwarfs to infer. This workshop will bring researchers across a number of disciplines together, including astrophysical plasma physics, high-energy gamma-ray astronomy, Lyman-alpha forest studies, and cosmological structure formation to foster collaborative interactions among them.
