Study of null geodesic in an axially symmetric space
Jonathan Pineda, Leonardo Castañeda, Juan Manuel Tejeiro
Since the development of Relativity theory, a variety of solutions have been found around Einstein field equations, depending on the time-space. For instance, we can find the axial…
Cosmological parameter estimation from weak lensing. The case of ,
Leonardo Castañeda
Propagation of light in the universe with structure which amplify and modify the shape of distant galaxies, producing a correlation between nearby and distant density of galaxies,…
Cosmological simulations: a tool for understanding the formation of large scale structure and connection with the Newtonian cosmology
J. E. García Farieta, L. Castañeda, J. M. Tejeiro
In this work we study the cosmological simulations as a tool to understand the formation of large-scale structure of the universe, for this, we show the equivalence of Newtonian co…
Equivalence between formulations in Cosmological Perturbation Theory: The primordial magnetic fields as an example
Hector J. Hortua, Leonardo Castañeda
Nowdays, Cosmological Perturbation Theory is a standard and useful tool in theoretical cosmology. In this work, we compare the 1+3 covariant formalism in perturbation theory (Ellis…
Shear Dynamics in Bianchi I Cosmology
Diego Caceres, Leonardo Castaneda, Juan M. Tejeiro
We present the exact equation for evolution of Bianchi I cosmological model, considering a non-tilted perfect fluid in a matter dominated universe. We use the definition of shear t…
