Uncovering the Physical Origins of Black Holes in the Milky Way for Astronomical Surveys

Ilia Kiato, Pierson Lipschultz, Vicky Kalogera +5

The observational landscape of stellar-mass black holes (BHs) in the Milky Way is expanding beyond X-ray binaries, with Gaia DR4 and Roman expected to open new windows onto BH popu…

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…

Stellar Population Spectra Incorporating Detailed Binary Evolution using POSYDON

Eirini Kasdagli, Jeff J. Andrews, Bret Lehmer +9

The accuracy of stellar population properties inferred through spectral energy distribution fitting hinges on the reliability of the underlying spectral models. Binary interactions…

Irregularly Sampled Time Series Interpolation for Binary Evolution Simulations Using Dynamic Time Warping

Ugur Demir, Philipp M. Srivastava, Aggelos Katsaggelos +9

Binary stellar evolution simulations are computationally expensive. Stellar population synthesis relies on these detailed evolution models at a fundamental level. Producing thousan…

Numerically stable equations for the orbital evolution of compact object binaries

Max M. Briel, Jeff J. Andrews

The orbital and eccentricity evolution for compact object binaries through gravitational wave emission first derived by Peters and Mathews are used extensively throughout the gravi…

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…

Not just winds: why models find binary black hole formation is metallicity dependent, while binary neutron star formation is not

L. A. C. van Son, S. K. Roy, I. Mandel +6

Both detailed and rapid population studies alike predict that binary black hole (BHBH) formation is orders of magnitude more efficient at low metallicity than high metallicity, whi…
