Generic modification of gravity, late time acceleration and Hubble tension
Mayukh R. Gangopadhyay, Shibesh K. Jas Pacif, M. Sami +1
We consider a scenario of large-scale modification of gravity that does not invoke extra degrees of freedom but includes coupling between baryonic matter and dark matter in the Ein…
Composite pseudo Nambu Goldstone Quintessence
Mayukh R. Gangopadhyay, Nilanjana Kumar, Ankan Mukherjee +1
A pseudo-Nambu Goldstone Boson (pNGB) arising from the breaking of a global symmetry () can be one of the most promising candidates for the quintessence model, to e…
The Oscillatory Universe, phantom crossing and the Hubble tension
Mohit K. Sharma, Shibesh Kumar Jas Pacif, Gulmira Yergaliyeva +1
We investigate the validity of cosmological models with an oscillating scale factor in relation to late-time cosmological observations. We show that these models not only meet the…
