A Four-dimensional Model-agnostic Probe into the Astrophysical Origins of Binary Black Hole Subpopulations
Anarya Ray, Vicky Kalogera
The paper presents a data-driven reconstruction of the four-dimensional joint distribution of binary black hole primary masses, mass ratios, effective inspiral spin, and effective…
LISA Reconstruction Landscape for Metastable Cosmic Strings
Satyabrata Datta, Rome Samanta
The authors model the stochastic gravitational-wave background from metastable cosmic strings and simulate LISA observations with instrumental noise and astrophysical foregrounds.…
Search for gravitational waves associated with high-energy neutrinos detected by IceCube during the third observing run of LIGO-Virgo
Matthias Vereecken, Matteo Pracchia, Kara Merfeld +3
The authors performed an unmodeled, targeted search for gravitational‑wave transients coincident with high‑energy neutrinos detected by IceCube during LIGO‑Virgo’s third observing…
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…
Domain walls through different cosmologies
I. Dankovsky, D. Gorbunov, S. Ramazanov +1
The paper uses lattice simulations to study how domain wall networks evolve under various early‑universe expansion histories, showing that the particle horizon largely determines w…
