A Dark Matter Model with Quadratic Equation of State: Background Evolution and Structure Formation
Kazem Rezazadeh, Ebrahim Yusofi, Alireza Talebian
We propose that dark matter (DM) possesses a quadratic equation of state, which becomes significant at high densities, altering the Universe's evolution during its early stages. We…
Spherical Collapse Approach for Non-standard Dark Matter Models and Enhanced Early Galaxy Formation in JWST
Zahra Davari, Amjad Ashoorioon, Kazem Rezazadeh
Using the spherical collapse approach, we investigate the impact of two alternative dark matter models, each characterized by distinct non-zero equations of state, one constant and…
Cascading Dark Energy
K. Rezazadeh, A. Ashoorioon, D. Grin
The standard cosmological model is in the midst of a stress test, thanks to the tension between supernovae-based measurements of the Hubble constant and inferences of its v…
