Multimessenger Signatures of Massive Black Holes in Dwarf Galaxies

Understand

Recent discoveries of massive black holes (MBHs) in dwarf galaxies suggest that they may have a more common presence than once thought.

• Systematic searches are revealing more candidates, but this process could be accelerated by predictions from simulations.
• We perform a study of several high-resolution, cosmological, zoom-in simulations focusing on dwarf galaxies that host massive black holes at z = 0, with the aim of determining when the black holes are most observable.
• Larger dwarf galaxies are more likely to host MBHs than those of lower mass.
