Cosmology without the cosmological principle: A study of the large-scale structure effects in the background universe
Erick Pastén
Recent studies strongly suggest that the CDM model may no longer serve as the definitive standard model in cosmology, given the increasing tensions between different cosmologica…
Reconstructing the kinematics of Laniakea using Type Ia Supernovae
Francesco Sorrenti, Erick Pastén, Leonardo Giani
We develop a kinematic framework that relates the monopole, dipole, and quadrupole of the luminosity distance to an ellipsoidal peculiar velocity field describing the dynamics of t…
Covariant interpretation of proper infall times in Kerr spacetime
Erick Pasten, Claudia Alvarez, Norman Cruz
We investigate proper infall times in the Schwarzschild and Kerr spacetimes from a covariant perspective, focusing on the role of black--hole rotation in the focusing properties of…
Approximations for the divergence of the local large-scale structure velocity field and its implications for Tilted Cosmology
Erick Pastén, Sebastián Gálvez, Víctor Cárdenas
We characterize the peculiar velocity field of the local large-scale structure reconstructed from the survey, by treating it as a fluid, extracting the divergence via differ…
