Head-on collisions of boson stars
read the original abstract
We study head-on collisions of boson stars in three dimensions. We consider evolutions of two boson stars which may differ in their phase or have opposite frequencies but are otherwise identical. Our studies show that these phase differences result in different late time behavior and gravitational wave output.

Lessons from binary dynamics of inspiralling equal-mass boson-star mergers
Numerical simulations of equal-mass boson-star mergers reveal larger waveform deviations from black-hole binaries in late inspiral and merger, plus odd multipole excitations for certain scalar-field phases, with some ...

Timing-Window Mechanism for Chain-Like Transients in Collisions of Radially Excited Boson Stars
Chain-like transients in boson star collisions are governed by a timing window set by the binary collision time relative to isolated breathing clocks rather than excitation level alone.

Boson star-black hole binaries: initial data and head-on collisions
A one-body conformal-factor correction stabilizes boson star-black hole initial data, enabling gravitational-wave analysis that shows higher multipoles can discriminate mixed mergers from pure black-hole binaries.

Establishing Compactness as a Population Observable in Gravitational-Wave Astronomy
Hierarchical analysis of GWTC-3 events measures effective compactness C_eff = 0.5^{+0.3}_{-0.1} consistent with black holes and limits low-compactness exotic merger rate to <0.7 Gpc^{-3} yr^{-1}.

Timing-Window Mechanism for Chain-Like Transients in Collisions of Radially Excited Boson Stars
Chain-like transients in boson star collisions are controlled by a timing window set by matching binary collision time to the isolated breathing clock rather than excitation level alone.

Massive boson stars: Stability and GW emission in head-on mergers
Numerical evolutions of quartically self-interacting boson stars reveal three merger outcomes and a non-monotonic gravitational-wave energy pattern driven by the competition between compactness and tidal deformability.

Compactness Inference in Gravitational-Wave Mergers with PhenomDECO: Catalog Benchmarks and Robustness Diagnostics
Compactness inference on GWTC-3 events confirms consistency with binary black hole sources after frequency-cut diagnostics show low-compactness modes are noise artifacts.

Massive boson stars: Waveform-based branch diagnosis with neural reconstruction
Using an existing numerical-relativity catalogue, the paper builds a branch-conditioned neural reconstruction model that infers boson-star merger outcomes from waveform morphology by comparing reconstruction quality a...
