High-resolution cosmological simulations of primordial dark matter clustering under long-range and fractional forces
Derek Inman
Long-range attractive fifth forces can lead to exponential instabilities in the early Universe. For fermions with a Yukawa coupling to a sufficiently light scalar mediator, rapid o…
Halo Formation from Yukawa Forces in the Very Early Universe
Guillem Domènech, Derek Inman, Alexander Kusenko +1
If long-range attractive forces exist and are stronger than gravity then cosmic halo formation can begin in the radiation-dominated era. We study a simple realization of this effec…
Robust field-level inference with dark matter halos
Helen Shao, Francisco Villaescusa-Navarro, Pablo Villanueva-Domingo +13
We train graph neural networks on halo catalogues from Gadget N-body simulations to perform field-level likelihood-free inference of cosmological parameters. The catalogues contain…
Enhanced Small-Scale Structure in the Cosmic Dark Ages
Derek Inman, Kazunori Kohri
We consider the consequences of a matter power spectrum which rises on small scales until eventually being cutoff by microphysical processes associated with the particle nature of…
Snowmass2021 Cosmic Frontier White Paper:Primordial Black Hole Dark Matter
Simeon Bird, Andrea Albert, Will Dawson +13
Primordial Black Holes (PBHs) are a viable candidate to comprise some or all of the dark matter and provide a unique window into the high-energy physics of the early universe. This…
CUBE -- Towards an Optimal Scaling of Cosmological N-body Simulations
Shenggan Cheng, Hao-Ran Yu, Derek Inman +3
N-body simulations are essential tools in physical cosmology to understand the large-scale structure (LSS) formation of the Universe. Large-scale simulations with high resolution a…
