Massive-photon electrodynamics and MHD in curved spacetime and cosmology
Jai-chan Hwang, Hyerim Noh
We study a massive-photon electrodynamics and magnetohydrodynamics (MHD) in the curved spacetime of Einstein's gravity. We consider a Proca-type photon mass and present equations i…

Evolution of baryon density perturbation in a relativistic MOND model based on Lorentz-violating vector field
Jai-chan Hwang, Hyerim Noh
A candidate for relativistic MOND with successful cosmology was proposed recently by using a Lorentz-violating vector field in Einstein's gravity. We show that the dynamic nature o…

Cosmological perturbations of a relativistic MOND theory
Jai-chan Hwang, Hyerim Noh
A relativistic MOND theory, promising in reproducing cosmology as well as the MOND phenomenology in the low acceleration regime, was recently proposed. We present the post-Newtonia…
