Ergosphere, Photon Region Structure, and the Shadow of a Rotating Charged Weyl Black Hole
Galaxies, 2021 In this paper, we explore the photon region and the shadow of the rotating counterpart of a static charged Weyl black hole, which has been previously discussed according to null and time-like geodesics. The rotating black hole shows strong sensitivity to

Magnetic response from constant backgrounds to Coulomb sources
European Physical Journal C: Particles and Fields, 2020 Within general nonlinear electrodynamics given by a local action, very special magnetic field configuration carrying no magnetic charge is found as a linear response of the vacuum, filled with constant electric and magnetic fields, to an embedded static ...

Space charge dynamics in low density polyethylene under dc electric fields
, 2007 In this paper space charge dynamics in low-density polyethylene (LDPE) under different dc electric fields, ranging from 25 kV/mm to 125 kV/mm, have been investigated using the pulsed electroacoustic (PEA) technique. Bipolar space charges have been formed
