Analysing Hubble Tension and Gravitational Waves for Gravity Theories
Shreya Banerjee, Aritrya Paul
In this work, we examine viable models of gravity theories against observational data with the aim to constrain the parameter space of these models. We have analysed five…

Primordial black holes and induced gravitational waves in non-singular matter bouncing cosmology
Theodoros Papanikolaou, Shreya Banerjee, Yi-Fu Cai +2
We present a novel model-independent generic mechanism for primordial black hole formation within the context of non-singular matter bouncing cosmology. In particular, considering…

Effect of Accretion on the evolution of Primordial Black Holes in the context of Modified Gravity Theories
Shreya Banerjee, Aritrya Paul
We investigates the effect of accretion of cosmic fluid on the evolution of Primordial Black Holes (PBHs) within the framework of Modified gravity theories. We consider a general f…
