Extending the Pulsar radio population through Quantum Vacuum Cherenkov Emission
Tales A. O. Gomes, Sergei V. Bulanov, Jaziel G. Coelho +3
The presence of some radio pulsars within and below the so-called ``death valley'' in the -- diagram challenges the standard pair-cascade models based on curvature radi…

Black hole and wormhole solutions in Einstein-Maxwell-Scalar theory
Júlio C. Fabris, Tales A. O. Gomes, Denis C. Rodrigues
We classified and studied the charged black hole and wormhole solutions in the Einstein--Maxwell system in the presence of a massless, real scalar field. The possible existence of…

Newtonian-like gravity with variable
Júlio C. Fabris, Tales Gomes, Júnior D. Toniato +1
We propose a Lagrangian formulation for a varying Newtonian-like theory inspired by the Brans-Dicke gravity. Rather than imposing an {\it ad hoc} dependence for the gravitation…
