From the simplest cosmological model that is consistent with the ART (Einstein-de Sitter model) thus follows the < Cosmic Time Hypothesis > (CTH), which offers solutions for many unsolved problems of cosmology that the current standard model of cosmology (ɅCDM model) cannot explain. According to the CTH, space, time and matter form a unit and develop evolutionarily according to identical, time-dependent laws. According to the CTH time has neither beginning nor end. The \"big bang\" disappears into the infinite past, which is why the universe manages without inflation. The accelerated expansion of the universe is also unlikely to occur if the SN-Ia measurement results are interpreted using the CTH. The cosmological constant Ʌ can then be omitted (Ʌ=0) and consequently no \"dark energy\" is needed. In addition, the CTH also provides interesting results on the topics: Initial conditions for hypotheses, stability of the expanding, flat universe (Ω=1), cosmic energy balance (is there negative energy ?), theory of earth expansion, unification of natural forces, Mach's principle. Should the CTH receive broad experimental confirmation, the GR could be extended to the \"Universal Relativity Theory\" (UR).","PeriodicalId":192286,"journal":{"name":"International Journal of Cosmology, Astronomy and Astrophysics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121254662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stationary shock wave solution of Burgers’ equation is obtained, and numerically analyzed in order to identify the basic properties of dust-ion-acoustic shock structures. It has been shown that depending on plasma parametric values, the degenerate plasma under consideration supports compressive or rarefactive shock structures. The relevance of our results in astrophysical objects like white dwarfs and neutron stars, which are of scientific interest, are briefly discussed.","PeriodicalId":192286,"journal":{"name":"International Journal of Cosmology, Astronomy and Astrophysics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134086477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that this level of the material world is preceded by the levels of elementary particles, atoms and molecules, which are characterized by a dual state – substance and field (wave-corpuscle). On this basis, the quantum of the space of the Universe with the wave parameters of the gravitational field was associated with the graviton, as a minimal real particle of the Universe. A new rationale for the relationship of the wave parameters of the gravitational field with the wave parameters of the electromagnetic field is also suggested, which is obtained on the basis of strict physical relationships composed of fundamental physical constants: the speed c of light in vacuum, the gravitational constant G and Planck’s constant h. On this basis, the possibility of linking the parameters of the quantum of the space of the Universe with a single photon is shown. The simplest physical and geometric scheme of the movement of a single photon in the space of the Universe is proposed. The proposed schemes reflect the initial physical structures of the material world, which do not contradict the known laws of physics, so they can be used for further studies of the graviton and photon.","PeriodicalId":192286,"journal":{"name":"International Journal of Cosmology, Astronomy and Astrophysics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131294189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model obtained shows a transition of the universe from decelerated phase to accelerated phase of the universe which is in accordance with the present scenario of modern cosmology.

However, this problem was not fully resolved, since the previously found elementary quantum of space in the form of a straight-sided prism did not correspond to the principle of minimalistic of the parameters of its shape. A new shape of the elementary quantum of the Universe in the form of a trihedral prism is proposed. This quantum is supplemented by its antipode, which has a mirror shape. In a connected form, they constitute a pair a dipole. A new circular quantum of the Universe space is formed from 6 such dipole pairs. Strong interconnection of neighboring quanta is ensured by the possibility of mutual penetration of their neighboring edges into each other, which follows from the Heisenberg uncertainty principle. The layering of 12 circular quanta on the top of each other provides them with a helical shape with a complete circular along their periphery, which reduces them to a mini-helix. New numerical values for the basic parameters of quanta and their interrelations are given. A new form of quanta and their new properties are of great importance for understanding the fundamentals of the material world. It has especially great significance for philosophy development, quantum physics, physics of elementary particles and cosmology.","PeriodicalId":192286,"journal":{"name":"International Journal of Cosmology, Astronomy and Astrophysics","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127330284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the compact size of the AGN central region, which is spatially unresolved with current observing facilities, we rely on spectropolarimetry which can provide us insight in their hidden physics. We model equatorial scattering for various broad line region (BLR) configurations using radiative transfer code STOKES. We analyze the polarization position angle () profiles for four supermassive binary black holes (SMBBHs) models and compare them with the profiles found for a unified model in AGNs with a single supermassive black hole (SMBH) and with notable outflowing velocity component of the BLR.. We find that the profiles for SMBBHs are axis-symmetric, while the profiles for a single SMBHs are point-symmetric and that there is a clear distinction between the two cases. Our conclussion is that spectropolarimetry might play a key role in the search for the SMBBHs by inspecting the polarization angle profiles.","PeriodicalId":192286,"journal":{"name":"International Journal of Cosmology, Astronomy and Astrophysics","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133863186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
