The impact of plasma instability cooling on intergalactic magnetic field constraints in GeV cascades for optimized instability cooling parameters
Suman Dey, Simone Rossoni, Günter Sigl
Electromagnetic cascades are initiated by TeV gamma rays propagating through the intergalactic medium (IGM), and they can be used to constrain the weak intergalactic magnetic field…

Impact of Plasma Instabilities and of the Intergalactic Magnetic Field on Blazar-Induced Electromagnetic Cascades
Suman Dey, Günter Sigl
Intergalactic weak magnetic fields can have non-negligible effects on the electromagnetic cascades induced by blazar gamma-ray emission. Secondary electrons and positrons are produ…

Simulations of Astrophysically Relevant Pair Beam Instabilities in a Laboratory Context
Suman Dey, Günter Sigl
The interaction of TeV blazars emitted gamma-rays with the extragalactic background photons gives rise to a relativistic beam of electron-positron () pairs propagating thr…
