Reheating in quintessential inflation via gravitational production of heavy massive particles: A detailed analysis
Jaume Haro, Weiqiang Yang, Supriya Pan
An improved version of the well-known Peebles-Vilenkin model unifying early inflationary era to current cosmic acceleration, is introduced in order to match with the theoretical va…
Reconstructing the dark matter and dark energy interaction scenarios from observations
Weiqiang Yang, Narayan Banerjee, Andronikos Paliathanasis +1
We consider a class of interacting dark energy models in a flat and nonflat FLRW universe where the interaction is characterized by the modified evolution of the pressureless dark…
Future Constraints on Dynamical Dark-Energy using Gravitational-Wave Standard Sirens
Minghui Du, Weiqiang Yang, Lixin Xu +2
The detection of gravitational waves (GW) by the LIGO and Virgo collaborations offers a whole new range of possible tests and opens up a new window which may shed light on the natu…
New observational constraints on gravity through gravitational-wave astronomy
Rafael C. Nunes, Supriya Pan, Emmanuel N. Saridakis
We investigate the new observational constraints on gravity that arise from the effects of primordial gravitational waves (GWs) on the cosmic microwave background (CMB) anis…
Observational constraints on dynamical dark energy with pivoting redshift
Weiqiang Yang, Supriya Pan, Eleonora Di Valentino +1
We investigate the generalized Chevallier-Polarski-Linder (CPL) parametrization, which contains the pivoting redshift as an extra free parameter. We use various data combinat…
Exact Solutions in Chiral Cosmology
Andronikos Paliathanasis, Genly Leon, Supriya Pan
In multi-scalar field cosmologies new dynamical degrees of freedom are introduced which can explain the observational phenomena. Unlike the usual scalar field theory where a single…
