• Abstract

  The central subject of this project is the model of black hole as an astrophysical object, i.e., a paradigm of compact object with a horizon. All the different aspects that we are interested have, in principle, an observational component. We shall study: a) the motion of test particles orbiting a black hole with different types of perturbations like, rings, disks, magnetic fields, bars, e…

• Abstract

  In the context of the modern cosmology the consequences of having a stochastic component in the density contrast function is considered, i.e., non-gaussian components of the density distribution are modeled using stochastic fields. N-body simulations in the presence of a massive central body are studied. Different schemas to consdier relativistic effects are presented. Also the formation …

• Abstract

  The application of the non-relativistic quantum theory to classically chaotic systems displays new phenomena, such as a completely different statistical distribution of the auto energies from the classical non-chaotic systems. Such results are confirmed both by theory and experiments. Using relativistic quantum mechanics, however, much less attention has been put forward. One of the excep…

• Abstract

  We are in a period where cosmology is quickly developing, both observationally and theoretically, and increasingly attracting other areas attention. Our purpose is to analyze the viability of modified gravity models as a solution to the cosmological problems; focusing on metric-affine gravity (MAG) and multi-gravity models. Besides their intrinsic value, they appear as effective models of…
