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…
Gravitational deflection of light in the Schwarzschild -de Sitter space time
Arunava Bhadra, Swarnadeep Biswas, Kabita Sarkar
Recent studies suggest that the cosmological constant affects the gravitational bending of photons although the orbital equation for light in Schwarzschild-de Sitter space time is…
Testing gravity at the Second post-Newtonian level through gravitational deflection of massive particles
A. Bhadra, K. Sarkar, K. K. Nandi
Expression for second post-Newtonian level gravitational deflection angle of massive particles is obtained in a model independent framework. Several of its important implications i…
Brans-Dicke theory: Jordan vs Einstein Frame
A. Bhadra, K. Sarkar, D. P. Datta +1
It is well known that, in contrast to general relativity, there are two conformally related frames, the Jordan frame and the Einstein frame, in which the Brans-Dicke theory, a prot…
Strong field gravitational lensing in scalar tensor theories
Kabita Sarkar, Arunava Bhadra
Strong field gravitational lensing in the Brans-Dicke theory has been studied. The deflection angle for photons passing very close to the photon sphere is estimated for the static…
On static spherically symmetric solutions of the vacuum Brans-Dicke theory
Arunava Bhadra, Kabita Sarkar
It is shown that among the four classes of the static spherically symmetric solution of the vacuum Brans-Dicke theory of gravity only two are really independent. Further by matchin…
