Effects of Self-Interaction and of an Ideal Gas in Binary Mergers of Bosonic Dark Matter Cores
Carlos Tena-Contreras, Ivan Alvarez-Rios, Francisco S. Guzman +1
We study binary mergers of dark matter cores in the Bose-Einstein condensate (BECDM) model. We include two scenarios: scalar self-interaction and the presence of a gravitationally…
Construction of ground state solutions of the Gross-Pitaevskii-Poisson system using genetic algorithms
Carlos Tena-Contreras, Ivan Alvarez-Rios, F. S. Guzman
We present the construction of the ground state of the Gross-Pitaevskii-Poisson equations using genetic algorithms. By employing numerical solutions, we develop an empirical formul…
Unveiling Orbital Chaos: The Wild Heart of Fuzzy Dark Matter Structures
Ivan Alvarez-Rios, Francisco S. Guzman
In this paper we study the behavior of test particles on top of a galactic-type of Fuzzy Dark Matter (FDM) structure, characterized by the core-halo density profile found in simula…
Numerical Solution Partial Differential Equations using the Discrete Fourier Transform
Daniela Rodriguez-Lara, Ivan Alvarez-Rios, Francisco S. Guzman
In this paper we explain how to use the Fast Fourier Transform (FFT) to solve partial differential equations (PDEs). We start by defining appropriate discrete domains in coordinate…
Black Holes as Condensation Points of Fuzzy Dark Matter Cores
Curicaveri Palomares-Chavez, Ivan Alvarez-Rios, Francisco S. Guzman
We simulate the formation of Fuzzy Dark Matter (FDM) cores in the presence of a Black Hole (BH) to explore whether BHs can serve as seeds for FDM core condensation. Our analysis is…
Fermion-Boson Stars as Attractors in Fuzzy Dark Matter and Ideal Gas Dynamics
Ivan Alvarez-Rios, Francisco S. Guzman, Jens Niemeyer
In the context of Fuzzy Dark Matter (FDM) we study the core formation in the presence of an Ideal Gas (IG). Our analysis is based on the solution of the Schrödinger-Poisson-Euler s…
Galactic Rotation Curves of LSB Galaxies using core-halo FDM configurations
Ivan Alvarez-Rios, Tula Bernal, Pierre-Henri Chavanis +1
In this work, we construct galactic halos in order to fit the rotation curves (RCs) of a sample of low surface brightness (LSB) galaxies. These halos are made of Fuzzy Dark Matter…
Construction and evolution of equilibrium configurations of the Schrödinger-Poisson system in the Madelung frame
Iván Alvarez-Ríos, Francisco S. Guzmán
We present the construction of ground state equilibrium configurations of the Schrödinger-Poisson (SP) system in the Madelung frame and evolve such configuration using finite volum…
Frequency shift of light emitted from growing and shrinking black holes
F. S. Guzman, I. Alvarez-Rios, J. A. Gonzalez
In this paper we present a method to study the frequency shift of signals sent from near a Schwarzschild black hole that grows or shrinks through accretion. We construct the numeri…
Merger of galactic cores made of ultralight bosonic dark matter
F. S. Guzman, J. A. Gonzalez, I. Alvarez-Rios
We study binary mergers of ultralight bosonic dark matter cores by solving the Gross-Pitaevskii-Poisson system of equations. The analysis centers on the dynamics of the relaxation…
