Cosmological Parameters and Gravitational Lensing Statistics [PDF]

Annals of the New York Academy of Sciences, 1995
The general idea of determining cosmological parameters with gravitational lensing statistics is outlined, and then recent work---with an emphasis on applicability to all cosmological models, observational bias, better statistics and robustness testing through numerical simulations---is discussed with relevance to a scheme originally introduced by ...

Planck2015 results [PDF]

Astronomy & Astrophysics, 2016
We present results based on full-mission Planck observations of temperature and polarization anisotropies of the CMB. These data are consistent with the six-parameter inflationary LCDM cosmology. From the Planck temperature and lensing data, for this cosmology we find a Hubble constant, H0= (67.8 +/- 0.9) km/s/Mpc, a matter density parameter Omega_m ...

Cosmological Constraints on Mirror Matter Parameters

Advances in High Energy Physics, 2014
Up-to-date estimates of the cosmological parameters are presented as a result of numerical simulations of cosmic microwave background and large scale structure, considering a flat Universe in which the dark matter is made entirely or partly of mirror ...

Revisiting the Hubble Constant, Sound Horizon, and Cosmography from Late-time Universe Observations

The Astrophysical Journal
The Hubble tension has become one of the central problems in cosmology. In this work, we determine the Hubble constant H _0 and sound horizon r _d by using the combination of baryon acoustic oscillations (BAOs) from DESI surveys, time-delay lensed ...

True CMB Power Spectrum Estimation [PDF]

, 2012
The cosmic microwave background (CMB) power spectrum is a powerful cosmological probe as it entails almost all the statistical information of the CMB perturbations. Having access to only one sky, the CMB power spectrum measured by our experiments is only

Cosmological parameters in noncommutative inflation [PDF]

Physics Letters B, 2004
We investigate how the uncertainty of noncommutative spacetime could explain the WMAP data. For this purpose, the spectrum is divided into the IR and UV region. We introduce a noncommutative parameter of $ _0$ in the IR region and a noncommutative parameter of $ _0$ in the UV region.

Comparison of cosmological models using standard rulers and candles

, 2015
In this paper, we used standard rulers and standard candles (separately and jointly) to explore five popular dark energy models under assumption of spatial flatness of the Universe.
