Heating and scattering of stellar distributions by ultralight dark matter
Andrew Eberhardt, Mateja Gosenca, Lam Hui
Due to wave interference, an ultralight light dark matter halo has stochastic, granular substructures which can scatter stars, leading to the heating of stellar distributions. Stud…
Aspherical ULDM Collapse: Variation in the Core-Halo Mass Relation
Emily Kendall, Mateja Gosenca, Richard Easther
Ultralight dark matter (ULDM) is an interesting alternative to the cold dark matter (CDM) paradigm. Due to the extremely low mass of the constituent particle ( eV),…
Commuter Count: Inferring Travel Patterns from Location Data
Nathan Musoke, Emily Kendall, Mateja Gosenca +4
In this Working Paper we analyse computational strategies for using aggregated spatio-temporal population data acquired from telecommunications networks to infer travel and movemen…
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…
AxioNyx: Simulating Mixed Fuzzy and Cold Dark Matter
Bodo Schwabe, Mateja Gosenca, Christoph Behrens +2
The distinctive effects of fuzzy dark matter are most visible at non-linear galactic scales. We present the first simulations of mixed fuzzy and cold dark matter, obtained with an…
WIMPs and stellar-mass primordial black holes are incompatible
Julian Adamek, Christian T. Byrnes, Mateja Gosenca +1
We recently showed that postulated ultracompact minihalos with a steep density profile do not form in realistic simulations with enhanced initial perturbations. In this paper we as…
Semiclassical path to cosmic large-scale structure
Cora Uhlemann, Cornelius Rampf, Mateja Gosenca +1
We chart a path toward solving for the nonlinear gravitational dynamics of cold dark matter by relying on a semiclassical description using the propagator. The evolution of the pro…
3D simulations with boosted primordial power spectra and ultracompact minihalos
Mateja Gosenca, Julian Adamek, Christian T. Byrnes +1
We perform three-dimensional simulations of structure formation in the early Universe, when boosting the primordial power spectrum on approximately kpc scales. We demonstrate that…
Spherically Symmetric N-body Simulations with General Relativistic Dynamics
Julian Adamek, Mateja Gosenca, Shaun Hotchkiss
Within a cosmological context, we study the behaviour of collisionless particles in the weak field approximation to General Relativity, allowing for large gradients of the fields a…
Dynamical Analysis of Scalar Field Cosmologies with Spatial Curvature
Mateja Gosenca, Peter Coles
We explore the dynamical behaviour of cosmological models involving a scalar field (with an exponential potential and a canonical kinetic term) and a matter fluid with spatial curv…
