Abstract

In this study, according to the Observation data obtained through two planck and WMAP satellites, in addition to studying and describing them, we obtain the highest adjustment and correlation between the calculated value and the observation of these data. However, these satellites periodic presentation of data from the universe, which has been modified in relation to previous data, therefore requires comparative and comparative analysis between them, and by determining the coefficient of correlation between them, we can find the best value of each parameter for using in cosmic models. However, By reviewing this article, the following results are obtained: 1. The Hubble parameter is presented as the most important factor in determining other basic parameters of cosmology and its values in various articles. According to recent data, the value of this parameter has been obtained over the past 25 years in the range of 50 < H0 (km/sec. Mpc) < 80, but the amount now considered as the most probable data for the current Hubble parameter, The latest announcement by Planck Satellite in 2015, H0 = 67. 9 ± 1. 5 (km/sec. Mpc). 2. Different density parameters such as ordinary and dark matter, baryonium, neutrino and dark energy were introduced as another fundamental parameter of cosmology and their methods of determination were investigated. Considering the very different data, the density of ordinary matter And the dark is in the range 0. 1 <Ω _m <0. 5. Also, the appropriate interval for the baryon density parameter is 0. 01 <Ω _b h^2 <0. 025. The last values given for the baronic density and cold dark matter and the whole world in 2015 were given by Planck satellite as Ω bh2= 0. 02217 ± 0. 00033 and Ω ch2= 0. 1186 ± 0. 0031. All quantities given by various papers for the total density of the universe support a value of Ω _0 ~ 1, and this represents the flat cosmology model for our current universe. With respect to this value of Ω _0, the current density of the universe is ρ 0(t) = 1. 880 × 10-29 h2 Ω (t) (gr/cm3). 3. The age of the universe was studied as one of the other fundamental parameters of the universe. By summarizing different data, an interval can be drawn 1. 2 × 10 10 (yrs) ≤ t0≤ 1. 8 × 10 10 (yrs) for the current age of the world, but according to the latest Planck satellite data, the most likely value for the current age of the world is 13. 82 Billions of years. Finally, a comparative analysis was carried out between some of the other important Cosmological parameters according to Planck and WMAP data that are used to solve some cosmic problems and astrophysics. This research can be used for any expert who considers astronomy and astrophysics issues as a guidebook for examining cosmic models.
