Milky Way satellite velocities reveal the Dark Matter power spectrum at small scales
Ivan Esteban, Annika H. G. Peter, Stacy Y. Kim
Dark Matter (DM) properties at small scales remain uncertain. Recent theoretical and observational advances have provided the tools to narrow them down. Here, we show for the first…
Snowmass2021 Cosmic Frontier White Paper: Cosmological Simulations for Dark Matter Physics
Arka Banerjee, Kimberly K. Boddy, Francis-Yan Cyr-Racine +15
Over the past several decades, unexpected astronomical discoveries have been fueling a new wave of particle model building and are inspiring the next generation of ever-more-sophis…
Core-collapse, evaporation and tidal effects: the life story of a self-interacting dark matter subhalo
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +5
Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter (DM) halo density profiles, from low-density cores to high-density core-collapsed cusps.…
Astrophysical Tests of Dark Matter with Maunakea Spectroscopic Explorer
Ting S. Li, Manoj Kaplinghat, Keith Bechtol +27
We discuss how astrophysical observations with the Maunakea Spectroscopic Explorer (MSE), a high-multiplexity (about 4300 fibers), wide field-of-view (1.5 square degree), large tel…
There is No Missing Satellites Problem
Stacy Y. Kim, Annika H. G. Peter, Jonathan R. Hargis
A critical challenge to the cold dark matter (CDM) paradigm is that there are fewer satellites observed around the Milky Way than found in simulations of dark matter substructure.…
In the Wake of Dark Giants: New Signatures of Dark Matter Self Interactions in Equal Mass Mergers of Galaxy Clusters
Stacy Y. Kim, Annika H. G. Peter, David Wittman
Merging galaxy clusters have been touted as one of the best probes for constraining self-interacting dark matter, but few simulations exist to back up this claim. We simulate equal…
