The maximum turnaround radius for axisymmetric cosmic structures
Sourav Bhattacharya, Theodore N Tomaras
Three simple idealised models are studied in order to develop some intuition about the leading order effect of non-sphericity on the maximum turnaround size of lar…
Comments on the entropic gravity proposal
Sourav Bhattacharya, Panagiotis Charalambous, Theodore N Tomaras +1
Explicit tests are presented of the conjectured entropic origin of the gravitational force. The gravitational force on a test particle in the vicinity of the horizon of a large Sch…
Cosmological screening and the phantom braneworld model
Sourav Bhattacharya, Stefanos R Kousvos, Stylianos Romanopoulos +1
The scalar and vector cosmological perturbations at all length scales of our Universe are studied in the framework of the phantom braneworld model. The model is characterized by th…
Cosmic structure sizes in generic dark energy models
Sourav Bhattacharya, Theodore N Tomaras
The maximum allowable size of a spherical cosmic structure as a function of its mass is determined by the maximum turn around radius , the distance from its centre…
Large scale structures and the cubic galileon model
Sourav Bhattacharya, Konstantinos F. Dialektopoulos, Theodore N. Tomaras
The maximum size of a bound cosmic structure is computed perturbatively as a function of its mass in the framework of the cubic galileon, proposed recently to model the dark energy…
Can Brans-Dicke theory with describe stars?
Sourav Bhattacharya, Konstantinos F. Dialektopoulos, Antonio Enea Romano +1
A step-by-step approach is followed to study cosmic structures in the context of Brans-Dicke theory with positive cosmological constant and parameter . First, it is shown th…
