Beyond Mergers: the Role of Metallicity in Forming a Reservoir of Massive and Detached Binary Black Hole Systems

Siyuan Chen, Monica Gallegos-Garcia

Isolated binary evolution is a key pathway to forming binary black hole (BBH) mergers. However, the observed gravitational-wave population indicates it may not account for all merg…

From the Milky Way to the Early Universe: How Metallicity Shapes the Formation of Double Neutron Stars

Abhishek Chattaraj, Jeff J. Andrews, Monica Gallegos-Garcia +10

Among the compact binaries detected through gravitational wave (GW) emission, double neutron stars (DNSs) hold the unique distinction of having well-characterized local analogs in…

The Mass-Ratio Distribution of the Low-Mass Binary Black Hole Subpopulation: A Natural Outcome of Isolated Binary Evolution

Monica Gallegos-Garcia, Anarya Ray, Vicky Kalogera +7

The observed merging binary black hole population is increasingly consistent with being composed of a mixture of subpopulations, each likely the result of different formation mecha…

High-mass binary black hole mergers from detailed binary evolution models

Max M. Briel, Olcay Bıyıklı, Tassos Fragos +10

Gravitational-wave observations reveal a population of binary black hole (BBH) mergers with primary masses above , extending into and potentially beyond…

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…

Formation of Stripped Stars From Stellar Collisions in Galactic Nuclei

C. Gibson, F. Kıroğlu, J. C. Lombardi +7

Tidal disruption events (TDEs) are an important way to probe the properties of stellar populations surrounding supermassive black holes. Observed spectra of several TDEs, such as A…

Tidal Disruption Events from Stripped Stars

Brenna Mockler, Monica Gallegos-Garcia, Ylva Götberg +2

Observations of tidal disruption events (TDEs) show signs of Nitrogen enrichment reminiscent of other astrophysical sources such as active galactic nuclei (AGN) and star-forming ga…

Angular Momentum Loss During Stable Mass Transfer onto a Compact object: the Effect of Mass Loss via Accretion Disk Winds

Monica Gallegos-Garcia, Jonatan Jacquemin-Ide, Vicky Kalogera

We use an analytic framework to calculate the evolution of binary orbits under a physically-motivated model that accounts for angular momentum loss associated with winds from an ac…

Evolutionary Origins of Binary Neutron Star Mergers: Effects of Common Envelope Efficiency and Metallicity

Monica Gallegos-Garcia, Christopher P L Berry, Vicky Kalogera

The formation histories of compact binary mergers, especially stellar-mass binary-black hole mergers, have recently come under increased scrutiny and revision. In this paper we rev…

Do high-spin high-mass X-ray binaries contribute to the population of merging binary black holes?

Monica Gallegos-Garcia, Maya Fishbach, Vicky Kalogera +2

Gravitational-wave observations of binary black hole (BBH) systems point to black hole spin magnitudes being relatively low. These measurements appear in tension with high spin mea…

Binary Black Hole Formation with Detailed Modeling: Stable Mass Transfer Leads to Lower Merger Rates

Monica Gallegos-Garcia, Christopher P L Berry, Pablo Marchant +1

Rapid binary population synthesis codes are often used to investigate the evolution of compact-object binaries. They typically rely on analytical fits of single-star evolutionary t…

The role of mass transfer and common envelope evolution in the formation of merging binary black holes

Pablo Marchant, Kaliroë M. W. Pappas, Monica Gallegos-Garcia +4

As the number of observed merging binary black holes (BHs) grows, accurate models are required to disentangle multiple formation channels. In models with isolated binaries, importa…

Winds in Star Clusters Drive Kolmogorov Turbulence

Monica Gallegos-Garcia, Blakesley Burkhart, Anna Rosen +2

Intermediate and massive stars drive fast and powerful isotropic winds that interact with the winds of nearby stars in star clusters and the surrounding interstellar medium (ISM).…

Tidal Disruptions of Main Sequence Stars of Varying Mass and Age: Inferences from the Composition of the Fallback Material

Monica Gallegos-Garcia, Jamie Law-Smith, Enrico Ramirez-Ruiz

We use a simple framework to calculate the time evolution of the composition of the fallback material onto a supermassive black hole arising from the tidal disruption of main seque…
