Pebbles to Gems: Intermediate-mass black holes in the first star clusters

Benedetta Mestichelli, Manuel Arca Sedda, Marta Volonteri +9

The rapid assembly of supermassive black holes (SMBHs) observed at requires efficient seeding mechanisms in the early Universe. Population III (Pop. III) star clusters…

Intermediate-mass black hole seeding in galactic nuclei from star cluster migration

Stefano Torniamenti, Nils Hoyer, Nadine Neumayer +2

Nuclear star clusters are one of the most favorable sites to host hierarchical black hole (BH) mergers, potentially bridging the gap from stellar-mass to massive BHs. However, thei…

Gravitational Waves from the Cosmic Dawn: Tracing Cosmic Black Hole Binaries with ET, LGWA and LISA

Nazanin Davari, Rosa Valiante, Alessandro Trinca +8

Next generation detectors, such as LISA, LGWA, and ET will, for the first time, probe the high redshift Universe, offering unique insight into the birth, growth, and dynamics of th…

Direct N-body simulations of rotating and extremely massive Population III star clusters

Kai Wu, Ataru Tanikawa, Francesco Flammini Dotti +6

Aims. We present eight direct N-body simulations with NBODY6++GPU of extremely massive, initially rotating Population III star clusters with 1.01 x 10^5 stars. Methods. Our models…

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…

Teen TITANS simulations -- I. Inefficient intermediate-mass black hole seeding via stellar collisions in young massive clusters

Benedetta Mestichelli, Sara Rastello, Michela Mapelli +2

Young massive clusters (YMCs) provide favorable environments for frequent stellar collisions, potentially leading to the formation of very massive stars (VMSs) and seeds of interme…
