Eccentric Stellar-mass Binary Black Holes: Population, Detectability, and Waveform Analysis in the LISA and LIGO Era
Zeyuan Xuan, Smadar Naoz, Kyle Kremer +3
Eccentric binary black holes (BBHs) formed through dynamical interactions can significantly contribute to gravitational wave (GW) detections. In this work, we present a simulated c…
Extracting Astrophysical Information of Highly-Eccentric Binaries in the Millihertz Gravitational Wave Band
Zeyuan Xuan, Smadar Naoz, Alvin K. Y. Li +6
Wide, highly eccentric () compact binaries can naturally arise as progenitors of gravitational wave (GW) mergers. These systems are expected to have a significant population…
A cosmological framework for stellar collisions at high redshift in proto-globular clusters, nuclear star clusters, and Little Red Dots
Claire E. Williams, Smadar Naoz, Sanaea C. Rose +8
Observations and cosmological simulations indicate that the early Universe hosted numerous compact, high-density stellar systems, where close encounters and physical collisions bet…
A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
Observing compact Pop III star clusters and the presence of cosmic streaming
Claire E. Williams, Smadar Naoz, Naoki Yoshida +7
The formation of the Universe's first luminous stellar structures depends on the unique conditions at "Cosmic Dawn," which are set by the underlying cosmological model and early ba…
Localizing Dynamically-Formed Black Hole Binaries in Milky Way Globular Clusters with LISA
Zeyuan Xuan, Kyle Kremer, Smadar Naoz
The dynamical formation of binary black holes (BBHs) in globular clusters (GCs) may contribute significantly to the observed gravitational wave (GW) merger rate. Furthermore, LISA…
