Off-center black hole seed formation? Implications for high and low redshift massive black holes
David Izquierdo-Villalba, Daniele Spinoso, Marta Volonteri +3
Recent studies show that light seeds of black holes, which grow into massive black holes (MBHs) over time, often struggle to remain at the centers of their birthplaces in high-reds…
Identifying massive black hole binaries via light curve variability in optical time-domain surveys
Alfredo Chiesa, David Izquierdo-Villalba, Alberto Sesana +5
Accreting massive black hole binaries (MBHBs) often display periodic variations in their emitted radiation, providing a distinctive signature for their identification. In this work…
Massive Star Clusters in the Semi-Analytical Galaxy Formation Model L-Galaxies 2020
Nils Hoyer, Silvia Bonoli, Nate Bastian +7
It is established that there exists a direct link between the formation history of star cluster populations and their host galaxies. However, our lack of understanding of the assem…
Lighting up the nano-hertz gravitational wave sky: opportunities and challenges of multimessenger astronomy with PTA experiments
Riccardo J. Truant, David Izquierdo-Villalba, Alberto Sesana +4
Pulsar Timing Array (PTA) experiments have the potential to unveil continuous gravitational wave (CGW) signals from individual massive black hole binaries (MBHBs). Detecting them i…
