- Connecting the Extremes: A Story of Supermassive Black Holes and Ultralight Dark Matter
- Time: 2:00 pm
- Speaker: Peter Denton, Brookhaven National Lab
- Abstract: Dark matter (DM) is known to interact gravitationally. If it is ultralight then there will be unique macroscopic effects that may be probable in the same environments that we see the evidence for DM. I will discuss how ultralight DM can be fermionic, evading the Tremaine-Gunn bound, and the new relevant constraints including those from supermassive black holes. Finally, I will present a specific model that addresses some interesting hints/anomalies in terms of early supermassive black hole formation, ultrafaint dwarf galaxies, and possible gravitational wave signatures.
