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…
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…
Test of conformal theory of gravity as an alternative paradigm to dark matter hypothesis from gravitational lensing studies
Shubhrangshu Ghosh, Mahasweta Bhattacharya, Yanzi Sherpa +1
Weyl's conformal gravity theory, which is considered as a compelling alternative to general relativity theory, has been claimed to describe the observed flat rotation curve feature…
Baryonic Tully-Fisher test of Grumiller's modified gravity model
Samrat Ghosh, Arunava Bhadra, Amitabha Mukhopadhyay +1
We test the Grumiller's quantum motivated modified gravity model, which at large distances modifies the Newtonian potential and describes the galactic rotation curves of disk galax…
Probing dark matter and dark energy through Gravitational Time Advancement
Samrat Ghosh, Arunava Bhadra, Amitabha Mukhopadhyay
The expression of gravitational time advancement (negative time delay) for particles with non-zero mass in Schwarzschild geometry has been obtained. The influences of the gravitati…
Exact relativistic Newtonian representation of gravitational static spacetime geometries
Shubhrangshu Ghosh, Tamal Sarkar, Arunava Bhadra
We construct a self-consistent relativistic Newtonian analogue corresponding to gravitational static spherical symmetric spacetime geometries, staring directly from a generalized s…
