On a debate about cosmic censor violation
Miguel Alcubierre, Jose A. Gonzalez, Marcelo Salgado +1
We review the arguments and counter arguments about the recent proposal for generic censorship violation. In particular the argument made in gr-qc/0405050 against our proposal for…
A unified Scenario for modeling the Galactic and Cosmological Dark Matter Components
Jose A. Gonzalez, Daniel Sudarsky
In this work we analyze the viability of use a particular models of scalar fields in the context of the galactic dark matter problem. These models are based on a single scalar fiel…
Dynamical evolution of unstable self-gravitating scalar solitons
Miguel Alcubierre, Jose A. Gonzalez, Marcelo Salgado
Recently, static and spherically symmetric configurations of globally regular self-gravitating scalar solitons were found. These configurations are unstable with respect to radial…
The cosmic censor conjecture: Is it generically violated?
Miguel Alcubierre, Jose A. Gonzalez, Marcelo Salgado +1
It has been recently argued by Hertog, Horowitz and Maeda, that generic reasonable initial data in asymptotically anti deSitter, spherically symmetric, space-times within an Einste…
Regularization of spherically symmetric evolution codes in numerical relativity
Miguel Alcubierre, Jose A. Gonzalez
The lack of regularity of geometric variables at the origin is often a source of serious problem for spherically symmetric evolution codes in numerical relativity. One usually deal…
