How greedy is the Universe? An entropy ledger and a causal envelope for early black hole growth
Fernando Izaurieta, Cristian Quinzacara, Omar Valdivia
The entropy of the observable Universe is dominated, by fifteen orders of magnitude, by the horizons of supermassive black holes, and gravitational collapse into black holes has of…

Gravitational Faraday Effect induced by Dark Matter Spin
F. Barriga, F. Izaurieta, S. Lepe +4
We show that the spin of dark matter induces a gravitational analog of the electromagnetic Faraday effect, where the polarization of gravitational waves undergoes a rotation as the…

Gravitational Waves in Einstein-Cartan Theory: On the Effects of Dark Matter Spin Tensor
E. Elizalde, F. Izaurieta, C. Riveros +2
This article studies the effects of an arbitrary dark matter spin tensor on the propagation of gravitational wave amplitude in the context of Einstein-Cartan theory. We choose to w…
