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…
Gravitational lensing study of cold dark matter led galactic halo
Samrat Ghosh, Arunava Bhadra, Amitabha Mukhopadhyay
In this work the space-time geometry of the halo region in spiral galaxies is obtained considering the observed flat galactic rotation curve feature, invoking the Tully-Fisher rela…
Influences of Dark Energy and dark matter on Gravitational Time Advancement
Samrat Ghosh, Arunava Bhadra
The effect of dark matter/energy on gravitational time advancement (negative effective time delay) has been investigated considering few dark energy/matter models including cosmolo…
