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…
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…
Evidence for axion miniclusters with an increased central density
Benedikt Eggemeier, Ananthu Krishnan Anilkumar, Klaus Dolag
We identify axion miniclusters collapsing in the radiation-dominated era and follow them to redshift with N-body simulations. We find that the majority of the densest minicl…
Post-inflationary structure formation boosted by parametric self-resonance
Benedikt Eggemeier, Peter Hayman, Jens C. Niemeyer +1
The post-inflationary Universe can pass through a long epoch of effective matter-dominated expansion. This era may allow for both the parametric amplification of initial fluctuatio…
The role of baryons in self-interacting dark matter mergers
Moritz S. Fischer, Nils-Henrik Durke, Katharina Hollingshausen +3
Mergers of galaxy clusters are promising probes of dark matter (DM) physics. For example, an offset between the DM component and the galaxy distribution can constrain DM self-inter…
Multifield Ultralight Dark Matter
Mateja Gosenca, Andrew Eberhardt, Yourong Wang +4
Ultralight dark matter (ULDM) is usually taken to be a single scalar field. Here we explore the possibility that ULDM consists of light scalar fields with only gravitational in…
