Binary neutron stars in the next-generation era: Multi-messenger detection prospects and constraints on the equation of state, mass distribution, and cosmology
Hauke Koehn, Thibeau Wouters, Gilad Sadeh +5
The paper forecasts how many binary neutron‑star mergers will be observed jointly in gravitational waves and electromagnetic light by next‑generation detectors like the Einstein Te…
Ab Initio Real-Time Gravitational-Wave Parameter Estimation
David Yallup, Metha Prathaban, James Alvey +4
The paper introduces a GPU‑optimized nested sampling algorithm that can perform rapid, full‑waveform gravitational‑wave parameter estimation for binary neutron star events, achievi…
Binary neutron star populations across cosmic time: the impact of binary stellar evolution uncertainties
Mathieu Venet, Irina Dvorkin
The paper examines how uncertainties in binary stellar evolution—especially common‑envelope efficiency and natal kick prescriptions—affect the formation efficiency and cosmological…
Evaluating KAGRA upgrade scenarios for multimessenger observations of binary neutron stars
Yuta Michimura, Soichiro Morisaki, Kenta Hotokezaka +1
The paper presents a fast method to assess how different KAGRA detector upgrades will affect the ability to locate binary neutron star mergers for multimessenger astronomy, compari…
Constraining initial orbital eccentricity of inspiral-dominated gravitational-wave events with an analytic approximant
Hemantakumar Phurailatpam, Gopakumar Achamveedu, Maria Haney +2
The paper introduces the TaylorF2Ecck frequency‑domain approximant for non‑spinning compact binaries on eccentric orbits, implements it in LALSuite, and applies it to GW170817 and…
