From cosmological simulations to binary black hole mergers: The impact of using analytical star formation history models on gravitational-wave source populations

Sasha Levina, Floor Broekgaarden, Lieke van Son +4

Observations of binary black hole (BBH) mergers provide a unique window into the lives of massive stars across cosmic time. Connecting redshift-dependent merger properties to massi…

A high fraction of close massive binary stars at low metallicity

H. Sana, T. Shenar, J. Bodensteiner +74

At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…

Where are Gaia's small black holes?

M. Fishbach, K. Breivik, R. Willcox +1

Gaia has recently revealed a population of over 20 compact objects in wide astrometric binaries, while LIGO-Virgo-KAGRA (LVK) have observed around 100 compact object binaries as gr…

A Mid-Thirties Crisis: Dissecting the Properties of Gravitational Wave Sources Near the 35 Solar Mass Peak

Soumendra Kishore Roy, Lieke A. C. van Son, Will M. Farr

One striking feature of binary black hole (BBH) mergers observed in the first decade of gravitational-wave astronomy is an excess of events with component masses around $35\,\mathr…

Binary stars take what they get: Evidence for Efficient Mass Transfer from Stripped Stars with Rapidly Rotating Companions

Thibault Lechien, Selma E. de Mink, Ruggero Valli +5

Binary stars and their interactions shape the formation of compact binaries, supernovae, and gravitational wave sources. The efficiency of mass transfer - the fraction of mass reta…

Prompt stellar and binary black hole mergers in tight triples: Insights from chemically homogeneous evolution

Alejandro Vigna-Gómez, Evgeni Grishin, Jakob Stegmann +7

Short-period massive binary stars are predicted to undergo chemically homogeneous evolution (CHE), making them prime candidates for producing binary black holes (BBHs) that may mer…

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…

Cosmology with Binary Neutron Stars: Does Mass-Redshift Correlation Matter?

Soumendra Kishore Roy, Lieke A. C. van Son, Anarya Ray +1

Next-generation gravitational wave detectors are expected to detect millions of compact binary mergers across cosmological distances. The features of the mass distribution of these…
