Fortifying gravitational-wave population inference with normalizing flows
Christian Adamcewicz, Hugh McDougall, Paul D. Lasky +1
As the LIGO-Virgo-KAGRA collaboration's (LVK's) gravitational-wave transient catalog grows, we are learning a wealth of information from the population properties of binary black h…
Sub-Torque-Balance Upper Limits on Continuous Gravitational Waves from Scorpius X-1
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1836
We present the results of a search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO data from the first part of the fourth LIGO-Virgo-KAGRA…
Searches for Binary Mergers with Sub-solar Mass Components in Data from the First Part of LIGO--Virgo--KAGRA's Fourth Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1832
We report on a gravitational wave search for compact binary coalescences involving at least one component with mass between to , and ratio of component m…
GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…
GWTC-4.0: Population Properties of Merging Compact Binaries
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1805
We detail the population properties of merging compact objects using 158 mergers from the cumulative Gravitational-Wave Transient Catalog 4.0, which includes three types of binary…
Do both black holes spin in merging binaries? Evidence from GWTC-4 and astrophysical implications
Christian Adamcewicz, Nir Guttman, Paul D. Lasky +1
Angular momentum transport in high-mass stars is commonly modeled by extrapolating the behavior of better-observed low-mass stars. According to the conventional picture, the cores…
GW231123: a Binary Black Hole Merger with Total Mass 190-265
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1771
On 2023 November 23 the two LIGO observatories both detected GW231123, a gravitational-wave signal consistent with the merger of two black holes with masses $137^{+23}_{-18}\, M_\o…
Structure and Skewness of the Effective Inspiral Spin Distribution of Binary Black Hole Mergers
Sharan Banagiri, Thomas A. Callister, Christian Adamcewicz +2
The detection of gravitational waves has brought to light a population of binary black holes that merge within a Hubble time. Multiple formation channels can contribute to this pop…
Swift-BAT GUANO follow-up of gravitational-wave triggers in the third LIGO-Virgo-KAGRA observing run
Gayathri Raman, Samuele Ronchini, James Delaunay +1819
We present results from a search for X-ray/gamma-ray counterparts of gravitational-wave (GW) candidates from the third observing run (O3) of the LIGO-Virgo-KAGRA (LVK) network usin…
No evidence for a dip in the binary black hole mass spectrum
Christian Adamcewicz, Paul D. Lasky, Eric Thrane +1
Stellar models indicate that the core compactness of a star, which is a common proxy for its explodability in a supernova, does not increase monotonically with the star's mass. Rat…
Which black hole is spinning? Probing the origin of black-hole spin with gravitational waves
Christian Adamcewicz, Shanika Galaudage, Paul D. Lasky +1
Theoretical studies of angular momentum transport suggest that isolated stellar-mass black holes are born with negligible dimensionless spin magnitudes . However, r…
Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…
Evidence for a correlation between binary black hole mass ratio and black-hole spins
Christian Adamcewicz, Paul D. Lasky, Eric Thrane
The astrophysical origins of the binary black hole systems seen with gravitational waves are still not well understood. However, features in the distribution of black-hole masses,…
Do unequal-mass binary black hole systems have larger ? Probing correlations with copulas in gravitational-wave astronomy
Christian Adamcewicz, Eric Thrane
The formation history of binary black hole systems is imprinted on the distribution of their masses, spins, and eccentricity. While much has been learned studying these parameters…
Heavy double neutron stars: birth, mid-life and death
Shanika Galaudage, Christian Adamcewicz, Xing-Jiang Zhu +2
Radio pulsar observations probe the lives of Galactic double neutron-star (DNS) systems while gravitational waves enable us to study extragalactic DNS in their final moments. By co…
