Equilibrium Halo Solutions of the Gross-Pitaevskii-Poisson System: The Role of the Particle Number
Francisco A. Guzmán, ElÃas Castellanos, Jorge Mastache
We investigate stationary halo-like solutions of the Gross-Pitaevskii-Poisson (GPP) system, which describes self-gravitating Bose-Einstein condensates with repulsive self-interacti…
Inverse-Scattering Reconstruction of Inflation from Scalar and Tensor Primordial Spectra
Jorge Mastache, Allan Hurtado
We develop an inverse-scattering framework to reconstruct the effective inflationary potentials governing scalar and tensor perturbations. By recasting the Mukhanov--Sasaki equatio…
Spectral distortions in the decaying QCD dark matter scenario
Jorge Mastache, Raúl Henriquez-Ortiz, Raúl Henriquez-Ortiz
We study the QCD--DM scenario by analyzing the imprint of energy injection from decaying dark-sector particles on the spectral distortions (SDs) of the Cosmic Microwave Background…
Non-Relativistic Boson Stars as Gravitational Quantum Droplets
Jorge Mastache, ElÃas Castellanos, Guillermo Chacón-Acosta
We analyze the dynamics of a gravitational bounded cloud of generic bosons or a boson star in the non-relativistic regime, assuming from the very beginning that the boson star is i…
