On the dark matter content of ultra-diffuse galaxies

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, , , , | Summary: I compare the dark matter content within stellar half-mass radius expected in a $Lambda$CDM-based galaxy formation model with existing observational estimates for the observed dwarf satellites of the Milky Way and ultra-diffuse galaxies (UDGs). The model reproduces the main properties […]

Warm and Fuzzy Dark Matter: Free Streaming of Wave Dark Matter

Kavli Affiliate: Wayne Hu | First 5 Authors: Rayne Liu, Wayne Hu, Huangyu Xiao, , | Summary: Wave or fuzzy dark matter that is produced with relativistic wavenumbers exhibits free streaming effects analogous to warm or hot particle dark matter with relativistic momenta. Axions produced after inflation provide such a warm or mildly relativistic candidate, […]

Warm Hawking Relics From Primordial Black Hole Domination

Kavli Affiliate: Gordan Z. Krnjaic | First 5 Authors: Christopher J. Shallue, Julian B. Muñoz, Gordan Z. Krnjaic, , | Summary: We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. If those dark-sector particles are stable, they would survive to the present […]
