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…

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…
