A Binary-Based Reassessment of the Age and Stellar Properties of NGC 7789 Using Twelve Binary Components

Kadri Yakut, Belinda Kalomeni, Saul Rappaport

We present a binary-based reassessment of the age of the intermediate-age open cluster NGC 7789, together with well-constrained stellar parameters for twelve components in six SB2…

ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves

Tim Dietrich, Tanja Hinderer, Micaela Oertel +40

Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…

Uncovering the population of compact binary mergers and their formation pathways with gravitational waves through the Einstein Telescope

M. Arca-Sedda, I. Dvorkin, G. Franciolini +19

Ground-based gravitational-wave (GW) observatories have transformed our view of compact-object mergers, yet their reach still limits a comprehensive reconstruction of the processes…

Binary Black Hole Mergers: Spin and mass ratio effects on gravitational waveforms

İsmail Özbakır, Kadri Yakut

We present a comprehensive parameter-space study of binary black hole (BBH) mergers using the SEOBNRv4\_opt waveform model. Our analysis spans simulated waveforms acros…

A Deep Look into the Intermediate-Age Open Cluster NGC 2506: What Binary Systems Reveal About Cluster Distance and Age

K. Yakut, B. Kalomeni, S. Rappaport +1

Using high-precision observations from the space-based \textit{Gaia} and \textit{TESS} missions, complemented by ground-based spectroscopic data and multi-band photometric surveys,…

A novel approach to determining the age of stellar clusters: application to NGC 188

K. Yakut, B. Kalomeni, S. Rappaport

We present a new independent determination for the age of one of the oldest open clusters, NGC 188: Gyr. We utilize a novel approach where we jointly fit the radial…
