A Systematic Study of the Stellar Populations and ISM in Galaxies out to the Virgo Cluster: near field cosmology within a representative slice of the local universe
feedback near-fi eld cosmology
2014/12/22
We present a compelling case for a systematic and comprehensive study of the resolved and unresolved stellar populations, ISM, and immediate environments of galaxies throughout the local volume, defin...
We present the method of describing an evolution in quantum cosmology in the framework of the reduced phase space quantization of loop cosmology. We apply our method to the flat Friedman-Robertson-Wal...
Dynamics and constraints of the Dissipative Liouville Cosmology
Cosmology dark matter dark energy
2011/10/11
In this article we investigate the properties of the FLRW flat cosmological models in which the cosmic expansion of the Universe is affected by a dilaton dark energy (Liouville scenario). In particula...
Higgs-Dilaton Cosmology: From the Early to the Late Universe

2011/10/18
We consider a minimal scale-invariant extension of the Standard Model of particle physics combined with Unimodular Gravity formulated in \cite{Shaposhnikov:2008xb}. This theory is able to describe not...
This is a brief review of the standard model of cosmology. We first introduce the FRW models and their flat solutions for energy fluids playing an important role in the dynamics at different epochs. W...
Observational test of inflation in loop quantum cosmology

2011/10/18
We study in detail the power spectra of scalar and tensor perturbations generated during inflation in loop quantum cosmology (LQC). After clarifying in a novel quantitative way how inverse-volume corr...

Abstract: We propose a general approa...
The cosmological perturbation theory in loop cosmology with holonomy corrections
cosmological perturbation loop cosmology
2010/3/18
In this paper we investigate the scalar mode of first-order metric perturbations over spatially flat FRW spacetime when the holonomy correction is taken into account in the semi-classical framework of...
Quantum field theory, gravity and cosmology in a fractal universe
Fractal spacetime Models of Quantum Gravity Cosmology of Theories beyond the SM
2010/3/18
We propose a model for a power-counting renormalizable field theory living in a fractal spacetime. The action is Lorentz covariant and equipped with a Stieltjes measure. The system flows, even in a cl...

Cosmic rays and their radiative processes in numerical cosmology。
In this paper we discuss the properties of the quasi-steady state
cosmological model (QSSC) developed in 1993 in its role as a cyclic model
of the universe driven by a negative energy scalar field. ...
Development of the concept of fractal cosmos after Anaxagoras has
been followed up to the present. It is shown how the concept reappeared in the
early Renaissance as a vague idea and subsequently to...
Exact Solutions of Brans-Dicke Cosmology and the Cosmic Coincidence Problem
Brans-Dicke Cosmology the Cosmic Coincidence Problem
2010/10/15
We present some cosmological solutions of Brans-Dicke theory, characterized by a decaying vacuum energy density and by a constant relative matter density. With these features, they shed light on the c...
