Investigating the formation channel of GW231123: Population III stars or hierarchical mergers?
Federico Angeloni, Konstantinos Kritos, Raffaella Schneider +5
The gravitational wave event GW231123, with component black hole masses lying within or above the pair-instability mass gap, poses a significant challenge to current stellar evolut…
Predicting intermediate-mass black hole formation in star clusters with machine learning
Konstantinos Kritos, Digvijay Wadekar, Emanuele Berti
Whether intermediate-mass black holes reside in nearby star clusters has remained contested for decades. We address this question by training neural network and random forest regre…
Milky Way Globular Clusters: Nurseries for Dynamically-Formed Binary Black Holes
Federico Angeloni, Konstantinos Kritos, Raffaella Schneider +4
We present a novel self-consistent theoretical framework to characterize the formation, evolution, and merger sites of dynamically-formed black hole binaries, with a focus on expla…
Supermassive black hole growth in hierarchically merging nuclear star clusters
Konstantinos Kritos, Ricarda S. Beckmann, Joseph Silk +5
Supermassive black holes are prevalent at the centers of massive galaxies, and their masses scale with galaxy properties, increasing evidence suggesting that these trends continue…
Black Holes merging with Low Mass Gap Objects inside Globular Clusters
Konstantinos Kritos, Ilias Cholis
Recently, the LIGO-Virgo collaborations have reported the coalescence of a binary involving a black hole and a low-mass gap object (LMGO) with mass in the range .…
Evaluating the Merger Rate of Binary Black Holes from Direct Captures and Third-Body Soft Interactions Using the Milky Way Globular Clusters
Konstantinos Kritos, Ilias Cholis
The multitude of binary black hole coalescence detections in gravitational waves has renewed our interest on environments that can be the cradle of these mergers. In this work we s…
