The imitation game: Proca stars that can mimic the Schwarzschild shadow

CAR Herdeiro, AM Pombo, E Radu… - … of Cosmology and …, 2021 - iopscience.iop.org
Can a dynamically robust bosonic star (BS) produce an (effective) shadow that mimics that
of a black hole (BH)? We focus on models of spherical BSs with free scalar or vector fields …

Coupled scalar-Proca soliton stars

AM Pombo, JMS Oliveira, NM Santos - Physical Review D, 2023 - APS
We construct and explore the physical properties of scalaroca stars: spherically symmetric
solitonic solutions made of a complex scalar field Φ and a complex Proca field A μ. We …

Shadows of boson and Proca stars with thin accretion disks

JL Rosa, D Rubiera-Garcia - Physical Review D, 2022 - APS
In this work, we obtain the shadow images of spherically symmetric scalar boson and Proca
stars using analytical fittings of numerical solutions, when illuminated by a geometrically thin …

Traversable wormholes in einstein-dirac-maxwell theory

JL Blázquez-Salcedo, C Knoll, E Radu - Physical Review Letters, 2021 - APS
We construct a specific example of a class of traversable wormholes in Einstein-Dirac-
Maxwell theory in four spacetime dimensions, without needing any form of exotic matter …

Search for subsolar-mass binaries in the first half of advanced LIGO's and advanced Virgo's third observing run

R Abbott, TD Abbott, F Acernese, K Ackley, C Adams… - Physical review …, 2022 - APS
We report on a search for compact binary coalescences where at least one binary
component has a mass between 0.2 M⊙ and 1.0 M⊙ in Advanced LIGO and Advanced …

Search for gravitational waves from the coalescence of subsolar-mass binaries in the first half of advanced LIGO and Virgo's third observing run

AH Nitz, YF Wang - Physical Review Letters, 2021 - APS
We present a search for gravitational waves from the coalescence of subsolar-mass black
hole binaries using data from the first half of Advanced LIGO and Virgo's third observing run …

Extreme-mass-ratio inspirals into rotating boson stars: Nonintegrability, chaos, and transient resonances

K Destounis, F Angeloni, M Vaglio, P Pani - Physical Review D, 2023 - APS
General relativity predicts that black holes are described by the Kerr metric, which has
integrable geodesics. This property is crucial to produce accurate waveforms from extreme …
