2017弦理论和宇宙学高登研究研讨会 （The Gordon Research Seminar on String Theory and Cosmology）
2017 弦理论和宇宙学高登研究 研讨会
2017/2/15
The Gordon Research Seminar on String Theory and Cosmology is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and ex...
2017弦理论和宇宙学戈登学术会议（The 2017 Gordon Research Conference on String Theory&Cosmology）
2017 弦理论和宇宙学戈登 学术会议
2017/1/11
This is the second Gordon Research Conference in the series on String Theory and Cosmology, initiated in Hong Kong in 2015. Cosmology, once a philosophical subject, has matured into a precision scienc...

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...
Recent years have witnessed the establishment of the concordance cosmology. Under the Cold Dark Matter scenario, cosmic structures are characteristic of dark matter haloes embedded in the cosmic web....
Four Fundamental Foreground Power Spectrum Shapes for 21 cm Cosmology Observations
Four Fundamental Foreground Power Spectrum Shapes Cosmology Observations
2012/2/24
Contamination from instrumental effects interacting with bright astrophysical sources is the primary impediment to measuring Epoch of Reionization and BAO 21 cm power spectra-an effect called mode-mix...
Gamma ray burst distances and the timescape cosmology
Gamma ray burst distances timescape cosmology
2011/10/20
Gamma ray bursts can potentially be used as distance indicators, providing the possibility of extending the Hubble diagram to redshifts ~7. Here we follow the analysis of Schaefer (2007), with the aim...
Power-law entropy-corrected HDE and NADE in Brans-Dicke cosmology
Power-law entropy-corrected HDE Brans-Dicke cosmology
2011/10/13
Considering the power-law corrections to the black hole entropy, which appear in dealing with the entanglement of quantum fields in and out the horizon, the holographic energy density is modified acco...
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...
Redshift and distances in a ΛCDM cosmology with non-linear inhomogeneities
cosmology: theory, relativity, large-scale structure of Universe, super- novae: general
2011/10/13
In this paper we study the effects of inhomogeneities on light propagation in a flat {\Lambda}CDM background. To this end we use exact solutions of Einstein's equations (Meures & Bruni 2011) where, st...
Viscous Little Rip Cosmology
Viscous Little Rip Cosmology
2011/10/17
Dark energy of phantom or quintessence nature with an equation of state parameter $w$ almost equal to -1 often leads the universe evolution to a finite-time future singularity. An elegant solution to ...
Quantum gravity stability of isotropy in homogeneous cosmology
quantum stability cosmological isotropy cosmological
2011/10/17
It has been shown that anisotropy of homogeneous spacetime described by the general Kasner metric can be damped by quantum fluctuations coming from perturbative quantum gravity in one-loop approximati...
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...
Testing the WMAP cosmology via Planck radio catalogues
methods: analytical - galaxies: general - cosmic microwave background- cosmology large-scale structure of Universe
2011/10/9
The prime evidence underpinning the standard LCDM cosmological model is the CMB power spectrum as observed by WMAP and other microwave experiments. But Sawangwit and Shanks have recently shown that th...
A way out of the dark age in cosmology
spacetime theory aether redshift cosmic expansion first principles
2011/8/4
Abstract: Current doctrines relevant to cosmology are criticized for not being well founded, not being based on definitions and unquestionable first principles alone or violating such principles. This...
