Contribution
It introduces a detailed analysis of pilgrim dark energy with different IR cut-offs and derives evolution equations, highlighting the phantom nature and parameter constraints.
Findings
Phantom cosmic evolution is supported in all scenarios.
The parameter μ must be less than zero for consistency.
Results align with Planck and WMAP9 observations.
Abstract
We study pilgrim dark energy model by taking IR cut-offs as particle and event horizons as well as conformal age of the universe. We derive evolution equations for fractional energy density and equation of state parameters for pilgrim dark energy. The phantom cosmic evolution is established in these scenarios which is well supported by the cosmological parameters such as deceleration parameter, statefinder parameters and phase space of and . We conclude that the consistent value of parameter is in accordance with the current Planck and WMAP results.
