Redshift Suppression of Nonlinear Scalar Fields in Accelerating FLRW Spacetimes
Mirda Prisma Wijayanto, Emir Syahreza Fadhilla, Ryan Sugihakim +3
We study small--data solutions of a nonlinear scalar field equation on spatially flat --dimensional FLRW spacetimes (). In conformal time the field satisfies a damped…

Radiative Maxwell Scattering on Slowly Rotating Weakly Charged Kerr-Newman Black Holes
Bobby Eka Gunara, Mulyanto, Emir Syahreza Fadhilla +1
We study real source-free Maxwell fields on slowly rotating, weakly charged Kerr-Newman exteriors and set up a finite-energy scattering theory after removal of the stationary Coulo…
