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…
Stochastic Gravitational Waves from Post-inflationary Structure Formation
Benedikt Eggemeier, Jens C. Niemeyer, Karsten Jedamzik +1
Following inflation, the Universe may pass through an early matter-dominated phase supported by the oscillating inflaton condensate. Initially small fluctuations in the condensate…
Inflationary and phase-transitional primordial magnetic fields in galaxy clusters
Salome Mtchedlidze, Paola Domínguez-Fernández, Xiaolong Du +4
Primordial magnetic fields (PMFs) are possible candidates for explaining the observed magnetic fields in galaxy clusters. Two competing scenarios of primordial magnetogenesis have…
Structure of Axion Miniclusters
David Ellis, David J. E. Marsh, Benedikt Eggemeier +3
The Peak-Patch algorithm is used to identify the densest minicluster seeds in the initial axion density field simulated from string decay. The fate of these dense seeds is found by…
Deep zoom-in simulation of a fuzzy dark matter galactic halo
Bodo Schwabe, Jens C. Niemeyer
Fuzzy dark matter (FDM) made of ultra-light bosonic particles is a viable alternative to cold dark matter (CDM) with clearly distinguishable small-scale features in collapsed struc…
Gravitational Collapse in the Post-Inflationary Universe
Benedikt Eggemeier, Bodo Schwabe, Jens C. Niemeyer +1
The Universe may pass through an effectively matter-dominated epoch between inflation and Big Bang Nucleosynthesis during which gravitationally bound structures can form on subhori…
