Gravitational time advancement effect in Bumblebee gravity for Earth bound systems
G. Y. Tuleganova, R. Kh. Karimov, R. N. Izmailov +3
This paper is a novel application of the new effect of gravitational time advancement or \textit{negative} time delay, first predicted for static black holes (spin ), that can…
Leptonic originated High energy neutrinos from astrophysical objects
Arunava Bhadra, Prabir Banik
High-energy neutrinos are traditionally regarded as unambiguous signatures of hadronic cosmic rays in astrophysical environments. Here we show that TeV neutrinos can instead be pro…
Ordinary Stars as Potential TeV Cosmic-Ray Accelerators
Prabir Banik, Arunava Bhadra, Sanjay K. Ghosh
Recent observations of cosmic rays increasingly point to the existence of nearby sources - so-called "local tevatrons", capable of accelerating particles to TeV energies. In this s…
Spherical accretion in the Schwarzschild spacetime in the Newtonian analogous construct
Shubhrangshu Ghosh, Souvik Ghose, Kalyanbrata Pal +2
The velocity-dependent Newtonian analogous potentials (NAPs) corresponding to general relativistic (GR) spacetimes accurately capture most of the relativistic features, including a…
