Videos

This page contains videos showing the evolution of an individual galaxy, a cluster of galaxies, a slice through the simulation, and an explanation of the sonification process. Use the controls in each section to explore the different models, scales, and properties available.

Individual galaxy

The videos below show the evolution of a galaxy in the L012m5 simulation from redshift z = 5.5 to z = 0. It has present-day stellar mass 1010.8 M, a star formation rate of 1.6 M/yr, and a black hole of mass 108.2 M. Stellar light videos include the effect of dust attenuation.

Cluster of galaxies

The videos below show the evolution of the largest cluster of galaxies in the L050m6 (thermal AGN feedback) and L050m6h (hybrid AGN feedback) simulations. This object has a present-day virial mass of 1014.2 M. The central galaxy has a stellar mass of 1011.6 M and a supermassive black hole with a mass of 109.6 M. On small-scale views the scale bar indicates a length of 100 physical kiloparsec (pkpc), about 300 thousand lightyears; on large-scale views it indicates 500 pkpc, about 1.6 million lightyears.

Box slice

Below are videos showing the evolution of various properties from redshift z = 17.5 to z = 0 of a 10 comoving megaparsec (cMpc) thick slice through the L050m6 simulations, which are 50 cMpc on a side (1 cMpc is about 3.3/(1+z) million lightyears). The sonification for this video is in stereo, with sound in the left (right) speaker coming from the left (right) side of the slice.

Sonification explanation

The COLIBRE videos include sonification using STRAUSS to augment what is seen. Sound is used to express the black hole accretion rate, the star formation and the energy outflow rate of galaxies as they evolve. These use rhythmic, musical and textural representations, respectively, to distinguish them. Watch the (accessible) explainer video below to understand more.
