“Hierarchical star cluster assembly boosts massive black hole seed formation”
Abstract: “Observations and high-resolution hydrodynamical simulations indicate that massive star clusters assemble hierarchically from sub-clusters with a universal power-law cluster mass function. We study the consequences of such an assembly for the formation of intermediate-mass black holes (IMBHs) at low metallicities with our updated N-body code BIFROST based on the hierarchical fourth-order forward integrator. BIFROST integrates few-body systems using secular and regularized techniques including post-Newtonian equations of motion up to order PN3.5 and gravitational-wave recoil kicks for merging BHs. Single stellar evolution is treated using the fast population synthesis code SEVN. We evolve three cluster assembly regions with up to 2.4 million stars following a realistic IMF in ~1000 sub-clusters for 50 Myr. IMBHs with masses up to Mbh ~ 2200 Msun form rapidly mainly via the collapse of very massive stars assembled through repeated collisions of massive stars followed by growth through tidal disruption events and BH mergers. No IMBHs originate from the stars in the initially most massive clusters due to suppression of hard massive star binary formation at high velocity dispersions and the competition between core collapse and massive star life-times. Later the IMBHs form subsystems resulting in gravitational-wave mergers with a 1000 Msun gravitational-wave detection being the observable prediction.”

(In Finnish) Marjatta ja Eino Kollin Säätiö
Säätiön tehtävänä on tukea tieteellistä sekä soveltavaa tutkimusta ja kehitystyötä myöntämällä apurahoja hankkeiden toteuttajille. Säätiö tarjoaa mahdollisuuksia yksittäisille tutkijoille ja kehittäjille sekä tutkimus-/ kehittäjäryhmille. Haasteena on ruokkia nimenomaan sellaista kehitystä, jolla olisi elinympäristömme kannalta positiivista vaikutusta pitkällä tähtäimellä. Apurahojen hakuaika on jatkuva.
