Focus on the small but powerful fraction of galaxies known as active galaxies. You’ll discover why observing across the full electromagnetic spectrum is essential to understanding them, and how their behaviour changes over time. This module introduces the main types of active galaxies and what distinguishes them.

Investigate the engines powering active galaxies. You’ll explore the idea that supermassive black holes drive enormous energy output through jets, and how viewing angle explains different galaxy types. The module also connects this model to some of the most extreme events in the universe, including gamma-ray bursts.

Examine the central role of black holes in shaping galaxies. You’ll see how they influence star formation by injecting energy into their surroundings, and how they are linked to galaxy growth. This module highlights the deep connection between black holes and the evolution of cosmic structure.

Zoom out to the biggest structures in the cosmos. Using data from large astronomical surveys, you’ll explore the cosmic web, a vast network of galaxies and gas. This module shows how these structures form, how they help explain missing matter, and how they support our current models of the universe.
