Isolated or Dynamical? Tracing Black Hole Binary Formation through the Population of Gravitational-Wave Sources
Manuel Arca Sedda, Lavinia Paiella, Cristiano Ugolini +5
The population of binary black hole (BBH) mergers observed by the LIGO-Virgo-KAGRA (LVK) collaboration offers a window into the cosmic evolution of compact binaries and their forma…
Seeds to success: growing heavy black holes in dense star clusters
Lavinia Paiella, Manuel Arca Sedda, Benedetta Mestichelli +1
The observational dearth of black holes (BHs) with masses between 100 and 100,000 raises questions about the nature of intermediate-mass black holes (IMBHs). Propos…
Piling up in the darkness: Features of the BBH mass distribution from isolated binaries
Cristiano Ugolini
After the third LIGO--Virgo--KAGRA observing run, the number of detected binary black hole (BBH) mergers became sufficient to identify statistical features of the population. We ex…
The assembly of intermediate black holes with complementary approaches: Dragon II and BPop
Cristiano Ugolini
Intermediate-mass black holes (IMBHs) occupy the range, but their existence remains poorly constrained. Only a few candidates have been suggested in dwarf…
