The ΛCDM model is also known as the standard model of cosmology, but is not related to theStandard Modelof particle physics. 9 参考 Maeder, Andre (2017). "An Alternative to the ΛCDM Model: The Case of Scale Invariance".The Astrophysical Journal.834(2): 194.arXiv:1701.03964.Bibcode:201...
Cosmologyearly universecosmic microwave backgroundRecent measurements of the cosmic microwave background radiation (CMB) from the WMAP satellite led to formulate a successful concordance cosmological model, termed ΛCDM. This model satisfactorily explains the origin and structure of the CMB temperature ...
The mass assembly of a whole population of sub-Milky Way galaxies is studied by means of hydrodynamical simulations within the $\\Lambda$-CDM cosmology. Our results show that while dark halos assemble hierarchically, in stellar mass this trend is inverted in the sense that the smaller the ...
cosmology : theoryhydrodynamicsintergalactic mediumlarge-scale structure of universequasars : absorption linesUtilizing a new, high mass resolution hydrodynamic simulation we compute the metallicity evolution of damped Lyman alpha systems (DLAs) and find a reasonable agreement with observations. In particular...
Modified gravity as an alternative for Lambda-CDM cosmology 3 By the variation of the action (2) with respect to the metric g µν , we obtain the equations corresponding to standard spatially-flat FRW universe 0 = −6H 2 P(φ) −Q(φ) −6H ...

Ever since the discovery that high redshift type Ia supernovae supported an accelerating universe, concordance cosmology orΛCDM, has come to dominate popular thinking. Although issues relating to the smallness ofΛhave given rise to several rival models of cosmic acceleration [1,2,3,4,5,6,7...
The newly released observational H(z) H(z) data (OHD) is used to constrain \Lambda(t) \Lambda(t) CDM models as holographic and agegraphic dark energy. By the use of the length scale and time scale as the IR cut-off including Hubble horizon (HH), future event horizon (FEH), age ...
The inflationary-$\Lambda$-Cold Dark Matter ($\Lambda$CDM) concordance cosmology builds on these assumptions to describe the origin and evolution of fluctuations. With standard assumptions about stress-energy sources, this system is specified by just seven phenomenological parameters, whose precise ...
Astrophysics - Cosmology and Nongalactic AstrophysicsThe study of the angular and spatial structure of the X-ray sky has been under investigation since the times of the Einstein X-ray Observatory. This topic has fascinated more than two generations of scientists and slowly unveiled an unexpected ...
