Much remains a mystery about the first billion years of the universe’s history, the epoch in which the cosmos emerged from its dark ages with the dawning of the earliest stars and galaxies. Now ...

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, ...

Surprisingly, some of the universe's brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a ...

Light transport simulation and rendering techniques form the backbone of modern computer graphics, enabling the creation of photorealistic images by accurately modelling the behaviour of light in ...
