Black hole vs. boson star
Comparison of ray-traced images of a Schwarzschild black hole and an ultracompact boson star. Figures made with FOORT, and used in our PRL paper.
Figures
White dwarf binaries and the GW background
The main plot from our A&A paper, in which we argue that extragalactic white dwarf binaries will dominate the stochastic gravitational-wave background in the LISA band.
Animations
This section contains example animations resulting from NR simulations with GRChombo.
The below animations show a head-on collision of a black hole flying into a more massive boson star (the setup mimics IB in 2307.02548)
Scalar field amplitude
This shows the boson star as it gets devoured by the black hole.
Conformal factor
This shows the black hole, prominently, and the boson star, less obvious.
Growth of the apparent horizon
This shows the black hole apparent horizon growing as it devours the boson star, while the black hole also slows down.
