The 47 pages that link to Galaxy merger, each with the reason it gives.

• Dynamical frictionRelated: Friction acting on satellite galaxies and their components helps remove orbital energy during a merger.

• Local GroupRelated: Interactions among major members shape the group’s future and its visible structure.

• Starburst galaxyRelated: Merger-driven tidal forces can funnel gas into a galaxy’s center and trigger intense star formation.

• Elliptical galaxyRelated: Major mergers can scramble stellar orbits and produce an elliptical remnant.

• Galaxy evolutionRelated: Mergers rearrange stars and gas, trigger star formation, or help end it.

• GalaxyRelated: Mergers redistribute stars and gas and can trigger bursts of star formation.

• Ram-pressure strippingCompared with: Mergers can transform gas-rich galaxies through gravitational interaction rather than environmental pressure.

• Spiral galaxyRelated: Mergers can reshape spiral disks or trigger bursts of star formation.

• Galaxy morphologyBroader topic: Mergers can transform disks into spheroidal systems or produce irregular forms.

• Galaxy formation and evolutionRelated: Mergers rearrange stars and gas and can trigger bursts or quench star formation.

• Hubble sequenceRelated: Mergers can distort galaxies beyond the orderly shapes represented by the sequence.

• Barred spiral galaxyCompared with: A merger can distort disks and bars, unlike the orderly structure of a settled barred spiral.

• Hierarchical structure formationBroader topic: Galaxy mergers are visible outcomes of the assembly of their host halos.

• Galactic diskRelated: Mergers can thicken, disrupt, or help regrow galactic disks depending on their properties.

• Lenticular galaxyRelated: Mergers can reshape disks and alter gas content, though they are not the only proposed pathway.

• Galaxy groupRelated: Frequent encounters in groups can drive mergers and reshape member galaxies.

• Galaxy interactionBroader topic: A close encounter can end with the galaxies merging into one system.

• Tidal tailRelated: Mergers can draw long tails from the galaxies as they pass and coalesce.

• Galaxy harassmentCompared with: Unlike a merger, harassment accumulates effects across fast passages that usually do not coalesce.

• Centaurus ANarrower topic: A merger between a large elliptical galaxy and a smaller gas-rich galaxy is a leading explanation for Centaurus A’s structure.

• Irregular galaxyRelated: Mergers can scramble disks and leave a galaxy with an irregular appearance.

• Antennae GalaxiesNarrower topic: The Antennae are a nearby example of a merger in progress.

• Galaxy ZooRelated: Classifications of disturbed galaxy shapes help identify possible merger stages.

• Omega CentauriRelated: Accretion and disruption may have delivered Omega Centauri into the Milky Way.

• Tidal dwarf galaxyRelated: Merger simulations test how often tidal dwarfs form and whether they persist afterward.

• Messier 87Related: M87’s enormous size and globular-cluster population preserve evidence of past mergers.

• Nuclear star clusterRelated: Mergers can deliver gas to galactic centers and trigger nuclear star formation.

• Satellite galaxyRelated: A satellite can become part of its host through orbital decay and merger.

• Ultraluminous infrared galaxyRelated: Mergers can concentrate gas and trigger the intense activity seen in many nearby ULIRGs.

• Luminous infrared galaxyRelated: Mergers can compress gas and trigger the intense activity seen in many nearby examples.

• Arp 220Narrower topic: The collision of two galaxies built Arp 220’s disturbed structure and concentrated its gas.

• Galaxy morphological classificationRelated: Mergers can reshape galaxies and produce disturbed morphologies.

• Ring galaxyRelated: A merger can create the encounter geometry and disturbances that produce a ring galaxy.

• Brightest cluster galaxyRelated: Repeated mergers can build the large stellar body of a central cluster galaxy.

• Hoag's ObjectRelated: A merger may have shaped the core or ring, though no remnant is firmly identified.

• IC 1101Related: Repeated mergers are a leading explanation for the growth of giant central galaxies.

• Peculiar galaxyRelated: Mergers can distort a galaxy's structure and trigger bursts of star formation.

• Andromeda–Milky Way collisionNarrower topic: A merger is a possible outcome of the predicted close encounter, not a guaranteed collision of stars.

• cD galaxyRelated: Repeated mergers can build the enormous stellar mass of a cD galaxy.

• Field galaxyRelated: Mergers remain an important route to structural change outside clusters.

• Interacting galaxyBroader topic: A close interaction can end in merger, transforming both galaxies into a single remnant.

• Intergalactic starRelated: Mergers can fling stars onto orbits that leave the resulting galaxy.

• MegamaserRelated: Mergers concentrate gas and dust, often creating conditions for powerful hydroxyl megamasers.

• Messier 49Related: Its structure and stellar halo can be studied for traces of past mergers.

• Thick diskRelated: A past merger can heat a pre-existing disk and contribute stars to a thick component.

• Formation and evolution of stars and galaxiesCompared with: Mergers can trigger star formation or disrupt disks, contrasting with quieter evolution.

• Starburst regionRelated: Mergers can drive gas toward galactic centers, where it fuels intense star formation.
