Animations are WebM, at the size they were rendered. Each one comes with the frame the site uses as its poster, which is the frame to take when a still image is what you need. Where a figure reproduces a published result, the page it is explained on gives the paper to cite alongside it, and that citation is the useful one.
Figures and animations
The project's name as a diffraction pattern
Simulated light passes through openings shaped like the letters GLOW and falls on a screen 100 mm behind them, resolving as the wavelength drops.

Diffraction through a circular hole
Visible light through a hole 200 micrometres across, one colour at a time: the rings contract as the wavelength falls.

What an opening's size does to its pattern
The opening changes size and shape, and the pattern it casts changes with it, which is how a diffraction pattern carries information about the object that made it.

What an opening's shape does to its pattern
A circle, triangle, square, pentagon and hexagon of equal area, each leaving a different imprint on the wave.

One lens across the whole frequency range
Nothing about the lens changes through the sweep: what changes is the ratio between its time-delay scale and the period of the wave.

Diffraction appearing as the alignment tightens
The impact parameter falls from 2.0 to 0.1 Einstein radii, the source crosses a caustic, and the amplification factor acquires the oscillations that are the signature of diffraction.

Building the arrival-time response of a lens
Isochrones of the Fermat potential sweep the lens plane for the best-fitting lens of GW231123, coloured by what each stretch contributes to the response.

How multiple images form
A wavefront is bent by a lens and folds back on itself, and the cusp where it intersects itself traces out a caustic.

Lensed sources against the detectable population
Where magnified sources sit relative to what current detectors can see, with GW231123 marked both as it is usually analysed and as the lensed analysis infers it.

From a galaxy to a distorted waveform
A galaxy splits the source into macroimages, one of which lands on a field of stars whose critical curves distort the signal.

A point mass inside an external potential
The external potential grows, enlarging the caustic and strengthening the wave-optics distortions that come with it.

Stochastic diffraction and the dark timbre
A frequency sweep through one realization of 2502 cold-dark-matter halos along the line of sight to a source at redshift 3.

Limits on compact objects as dark matter
Existing bounds on the abundance of compact objects against their mass, with bands showing the masses each wave-optics probe reaches.

Gravitational-wave birefringence
A signal crossing a Vainshtein-screened lens, where the two polarizations travel differently and the waveform carries the difference.

Parameter estimation in two dimensions
A sampler exploring a two-parameter lens model, with each point a candidate and the posterior emerging from the ones that survive.

Ten thousand stellar fields, reduced to a basis
Distortion curves from ten thousand simulated fields collapse into a mean and a one-sigma band, and the first six modes carry most of the variance.

Logos
The two marks below identify the project and the code, and they are not covered by the licence above: use them to refer to GLOW or to GLoW, and do not alter them. Each comes in two versions, one for placing on a dark background and one for a light background, both with transparency. Ana Carvalho designed them.
GLOW, the project

GLoW, the code
The mark of the wave-optics code, different from the ERC project.
