Modern tidal interaction models for rapid binary population synthesis: II. Binary black hole formation, mergers, and spins
Veome Kapil, Ilya Mandel, Jeff Riley +3
We present predictions for the merger rates and effective spin () distribution of binary black holes (BBHs) from isolated binary evolution, using a new self-consisten…
Improving low-latency multi-messenger follow-up of neutron star-black hole mergers with mode-by-mode filtering
Francesco Iacovelli, Digvijay Wadekar, Javier Roulet +2
Rapid parameter estimation for neutron star-black hole (NSBH) mergers is essential for deciding whether, where, and how electromagnetic facilities should follow up gravitational-wa…
Primordial Black-Hole-Based Pathways to Little Red Dots
Valerio De Luca, Loris Del Grosso, Gabriele Franciolini +4
The James Webb Space Telescope has uncovered a population of compact, high-redshift sources, the Little Red Dots (LRDs), which may host supermassive black holes (BHs) significantly…
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…
