High-mass binary black hole mergers from detailed binary evolution models
Max M. Briel, Olcay Bıyıklı, Tassos Fragos +10
The paper uses detailed binary evolution simulations to test whether super‑Eddington mass transfer in isolated binaries can produce the observed high‑mass binary black hole mergers…
How Common Are Common Envelopes? Quantifying Their Role in Forming Gravitational-Wave Sources
Floor S. Broekgaarden, Ana Lam, Sasha Levina +14
A central goal of gravitational-wave astronomy is to use merging binary black hole (BBH), black hole-neutron star (BHNS), and binary neutron star (BNS) systems as fossils to recons…
A case for Case A: detailed look at binary black hole formation through stable mass transfer
Max M. Briel, Tassos Fragos, Monica Gallegos-Garcia +8
In isolated binary evolution, binary black hole (BBH) mergers are generally formed through stable mass transfer (SMT) or common envelope evolution. In recent years, the SMT channel…
Spectral Diversity in Type Ibn Supernovae and the Large Host Offset of SN2024acyl
Yize Dong, V. Ashley Villar, Anya Nugent +35
In this paper, we first present observations of SN~2024acyl, a normal Type Ibn supernova with a large projected offset (35~kpc) from its host galaxy. The low star-formation r…
POSYDON Version 2: Population Synthesis with Detailed Binary-Evolution Simulations across a Cosmological Range of Metallicities
Jeff J. Andrews, Simone S. Bavera, Max Briel +21
Whether considering rare astrophysical events on cosmological scales or unresolved stellar populations, accurate models must account for the integrated contribution from the entire…
