GALACTIC WINDS – Outflows of gas driven by supernovae and AGN activity, affecting galaxy evolution.

METALLICITY EVOLUTION – The increasing abundance of heavy elements in galaxies over time due to stellar processes.

AGN (ACTIVE GALACTIC NUCLEUS) – A highly energetic region at a galaxy’s center, often influencing star formation.

ELLIPTICAL GALAXY FORMATION – The result of major galaxy mergers that disrupt disk structures.

REDSHIFT – The shifting of light to longer wavelengths as galaxies move away due to cosmic expansion.

INTERGALACTIC MEDIUM (IGM) – The tenuous gas and plasma between galaxies, playing a role in galaxy evolution.

TIDAL FORCES – Gravitational interactions that distort and shape galaxies during mergers.

GALAXY MERGERS – The process where two or more galaxies collide and combine, influencing their evolution.

STARBURST GALAXIES – Galaxies experiencing an intense period of star formation, often triggered by mergers.

QUASARS – Extremely bright, distant objects powered by supermassive black holes, often seen in young galaxies.
