From scalar clouds around evaporating black holes to boson star
Daniel Neves, João G. Rosa
We study, for the first time, the evolution of a scalar cloud bound to an evaporating black hole. Our simulations of the associated Schrödinger-Poisson system for non-relativistic…
Dark neutron stars from a heavy dark sector
Jacob A. Litterer, João G. Rosa
We study the formation and properties of dark neutron stars in a scenario where dark matter is made up of (heavy) dark baryons in a sequestered copy of the MSSM. This scenario natu…
Constraints on Dark Matter Structures around Gaia Black Holes
Nuno P. Branco, Ricardo Z. Ferreira, João G. Rosa +1
We demonstrate that Gaia's detection of stars on wide orbits around black holes opens a new observational window on dark matter structures -- such as scalar clouds and dark matter…
Preheated inflation
Diogo S. Gorgulho, João G. Rosa
We propose a new mechanism of non-thermal particle production during inflation based on a narrow parametric resonance, akin to the dynamics of post-inflationary preheating. The mec…
