constraining the variable generalized chaplygin gas model in matter creation cosmology

引用

communications in Theoretical physics 2024年第10期76卷 121-136页

作者： Yogesh Bhardwaj c p singh Department of Applied mathematics Delhi Technological University

We explore the variable generalized chaplygin gas（VGcG） model in the theory of matter creation cosmology within the framework of a spatially homogeneous and isotropic flat Friedmann—Lemai tre—robertson—Walker space-time. matter creation cosmology is based on reinterpretation of the energy–momentum tensor in Einstein's field equations. This creation corresponds to an irreversible energy flow from the gravitational field to the created matter constituents. The variable chaplygin gas（VcG） is also studied as a particular solution. We use the markov chain monte carlo method to constrain the free parameters of three models, namely,Lambda-cold-Dark matter（ΛcDm）, VGcG and VcG models with and without matter creation from the latest observational data from baryon acoustic oscillations, cosmic chronometer, type Ia supernovae（pantheon） including gamma-ray bursts, quasars and the local measurement of H0from r21 data. Two different combinations of dataset provide a fairly tight constraint on the parameters of the ΛcDm, VGcG and VcG models. The present values of various cosmological parameters are obtained, which are very close to the ΛcDm model. Furthermore, we perform stability analysis, Bayesian evidence analysis and information criteria analysis for these models through studying the sound speed, Bayes factor, and Akaike information criteria（AIc） and Bayesian information criteria（BIc） selection criteria. The values of sound speed for VGcG and VcG models shows that both the models are stable. According to AIc, it is observed that VGcG and VcG models with matter creation are supported considerably less by current observations,while BIc shows that these models are not favoured by observational data.

sp100 is an antiviral protein that restricts the productive stage of human papillomavirus(HpV)and multiple other viruses,and viruses in turn block sUmO-1-mediated stabilization of sp100 and promotes its degradation(Table s1).Interferon(IFN)signaling could still produce more sp100 through transcription to counteract viruses.1 Viruses also disable the transcriptional up-regulation of sp100 to achieve persistent infection in hosts.
