Marginal Role of the Electrostatic Instability in the GeV-scale Cascade Flux from 1ES 0229+200

Relativistic pair beams produced in the intergalactic medium by TeV gamma rays from blazars are expected to generate a detectable GeV-scale electromagnetic cascade, yet this cascade is absent in the observed spectra of hard-spectrum TeV emitting blazars. This suppression is often attributed to weak...
