Scientific animation
Neutrino mass and the growth of cosmic structure
A visual comparison of cosmic structure with and without massive neutrinos, highlighting the suppression of power on small scales.
Cosmic-web panels compare total neutrino masses of zero and 0.4 eV. A graph shows the relative linear matter power for three neutrino masses, with smaller scales highlighted.

About this visualization
The animation compares cosmic structure in two scenarios: a total neutrino mass of zero and 0.4 eV. The side-by-side view highlights differences in the appearance of small-scale structure.
What to look for
The final graph shows the ratio of the linear matter power spectrum to the massless-neutrino case at redshift zero, for total neutrino masses of 0.1, 0.2, and 0.4 eV. The highlighted small-scale region emphasizes where the suppression is more pronounced.
Available versions
The main version has a light background and includes the power-spectrum comparison. A 40-second alternative with a dark background is also available in the downloads. The animations have no audio narration; the explanation above describes their main scientific message.
