Discrete self-similarity imprints on primordial-black-hole mass functions
Luis E. Padilla, Tomohiro Harada, Hayami Iizuka
We study how discrete self-similarity (DSS) in the critical behavior of scalar-field collapse is imprinted on primordial-black-hole (PBH) mass functions. Using the DSS-modulated cr…
Long-wavelength non-linear perturbations of a complex scalar field
Luis E. Padilla, Juan Carlos Hidalgo, Darío Núñez
We study the evolution of nonlinear superhorizon perturbations in a universe dominated by a complex scalar field. The analysis is performed adopting the gradient expansion approach…
On the Possibility that Ultra-Light Boson halos host and form Super-massive Black Holes
Ana Avilez-Lopez, Luis Padilla-Albores Luis, Tula Bernal-Marin +1
Several observations suggest the existence of super-massive black holes (SMBH) at the centers of giant galaxies. However the mechanism under which these objects form remains non co…
