Phantom cosmology with arbitrary potential: New accelerating scaling attractors
Sudip Halder, Supriya Pan, Paulo M. Sá +1
In this article, we investigate the existence of accelerating scaling solutions in coupled phantom cosmology without assuming any specific potential for the phantom scalar field. T…
Parametrizing the Hubble function instead of dark energy: Many possibilities
Sivasish Paul, Raj Kumar Das, Supriya Pan
In the present article, we propose a very simple parametrization of the Hubble function without parametrizing the dark components of the Universe. One of the novelties of the param…
Is Dark Energy an Effective Manifestation of Non-equilibrium Thermodynamics? -- Insights from DESI
Sauvik Bhattacharjee, Sudip Halder, Jaume de Haro +2
We investigate the background cosmological expansion on the onset of cosmological homogeneous matter creation scenario, a dynamical dark matter approach (), and…
Matter Creation Cosmologies and Accelerated Expansion
Sudip Halder, Jaume de Haro, Supriya Pan +2
Non-conservation of dark matter can lead to late-time cosmic acceleration. This mechanism is known as the matter creation theory and this replaces the need of dark energy and modif…
