When the black holes align: a subpopulation of aligned massive binary black holes observed via gravitational waves
Stefano Rinaldi, Charmaine Wong, M. Paola Vaccaro +4
In this work, we investigate the features present in the joint primary mass and effective spin distribution of binary black holes without relying on specific modelling assumptions.…
Prospects for optical detections from binary neutron star mergers with the next-generation multi-messenger observatories
E. Loffredo, N. Hazra, U. Dupletsa +13
Next-generation gravitational wave (GW) observatories, such as the Einstein Telescope (ET) and Cosmic Explorer, will observe binary neutron star (BNS) mergers across cosmic history…
Gravitational-wave constraints on the pair-instability mass gap and nuclear burning in massive stars
Fabio Antonini, Isobel Romero-Shaw, Thomas Callister +5
Pair-instability should prevent the direct formation of black holes above about creating a pair-instability mass gap. Yet gravitational-wave observations have detected…
Impact of initial mass function on the chemical evolution of high-redshift galaxies
Boyuan Liu, Michela Mapelli, Volker Bromm +10
Recent observations by the James Webb Space Telescope (JWST) have found evidence for an invariant relation between stellar mass, metallicity, and star formation rate up to $z\sim 8…
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…
The role of migration traps in the formation of binary black holes in AGN disks
Maria Paola Vaccaro, Yannick Seif, Michela Mapelli
Binary black holes (BBHs) forming in the accretion disks of active galactic nuclei (AGNs) represent a promising channel for gravitational-wave production. BBHs are often assumed to…
