On Bimodality in the Eccentricity Distribution of Galactic Double Neutron Stars
Aldana Grichener, Paul Disberg, Ryosuke Hirai +1
The detection of Galactic double neutron stars (DNSs) through pulsar timing offers a unique opportunity to probe massive stellar and binary evolution. The observed DNS population e…
Search For a Counterpart to the Subsolar Mass Gravitational Wave Candidate S251112cm
Nicholas Vieira, Noah Franz, Bhagya Subrayan +49
The recent candidate gravitational-wave (GW) alert from a compact object merger involving at least one subsolar mass (SSM) object has prompted questions about their origins. S25111…
Unraveling the Origin of Unequal Mass Gravitational Wave Events: Insights from a Galactic High Mass X-ray Binary
Neev Shah, Mathieu Renzo, Koushik Sen +2
The catalog of Gravitational Wave (GW) events is rapidly growing, providing key insights into the evolution of massive binaries and compact object formation. However, a key challen…
Interacting binaries on the Main Sequence as in-situ tracers of mass transfer efficiency and stability
Koushik Sen, Mathieu Renzo, Harim Jin +8
Understanding the transfer of mass and angular momentum in binary interactions is crucial for modelling the evolution of any interacting binary after the first mass transfer phase.…
Circumbinary disks in post common envelope binary systems with compact objects
Lotem Unger, Aldana Grichener, Noam Soker
We conduct a population synthesis study using the binary population synthesis code compas to explore the formation of circumbinary disks (CBDs) following the common envelope evolut…
Optimizing Kilonova Searches: A Case Study of the Type IIb SN 2025ulz in the Localization Volume of the Low-Significance Gravitational Wave Event S250818k
Noah Franz, Bhagya Subrayan, Charles D. Kilpatrick +54
Kilonovae, the ultraviolet/optical/infrared counterparts to binary neutron star mergers, are an exceptionally rare class of transients. Optical follow-up campaigns are plagued by c…
