In this study,we revisit supersymmetric(SUSY)hybrid inflation within the context of considering the latest Cosmic Microwave Background(CMB)observations and swampland conjectures.We demonstrate that SUSY hybrid inflati...

Pulsar timing array(PTA)data releases show strong evidence for a stochastic gravitational-wave background in the nanohertz band.When the signal is interpreted by a scenario of scalar-induced gravitational waves(SIGWs)...

In this study,we constructed ten dark energy models to test whether they can reconcile the Hubble tension and how much it is affected by parameterization.To establish a fair test,the models are diverse,encompassing fr...

We explore the theoretical possibility that dark energy density is derived from massless scalar bosons in vacuum and present a physical model for dark energy. By assuming massless scalar bosons fall into the horizon b...

We investigate the power spectra of the CMB temperature and matter density in the running vacuum model(RVM) with the time-dependent cosmological constant of A=3 vH^2+ Λ_0, where H is the Hubble parameter. In this mod...

According to inflationary cosmology, the CMB anisotropy gives an opportunity to test predictions of new physics hypotheses. The initial state of quantum fluctuations is one of the important options at high energy scal...

The influence of cosmological constant-type dark energy in the early universe is investigated. This is accommodated by a new dispersion relation in de Sitter spacetime. We perform a global fit to explore the cosmologi...

The WMAP and Planck observations show that the quadrupole and octopole orientations of the CMB might align with each other. We reveal that the quadrupole-octopole alignment is a natural implication of the primordial p...
