Linked from

The 16 pages that link to Seyfert galaxy, each with the reason it gives.

• Active galactic nucleusBroader topic: Seyfert galaxies provide nearby, comparatively accessible examples of nuclear activity.

• QuasarCompared with: Seyfert nuclei share quasar-like activity but are generally less luminous.

• Radio galaxyCompared with: Seyfert galaxies are active, but generally lack the vast radio lobes characteristic of powerful radio galaxies.

• BlazarCompared with: Its nucleus is generally viewed away from the jet axis, unlike a blazar.

• Centaurus ACompared with: Seyfert galaxies are another active-nucleus class, usually distinguished by weaker extended radio structures.

• UhuruRelated: Uhuru detected X-ray emission from active galactic nuclei, including Seyfert galaxies.

• Whirlpool GalaxyCompared with: The Whirlpool’s bright central region is not what defines its identity; its grand-design disk does.

• Messier 81Compared with: M81’s nucleus is comparatively faint, despite evidence for accretion onto its central black hole.

• Messier 77Broader topic: Messier 77 is the prototype of a Seyfert 2 galaxy.

• NGC 1275Related: NGC 1275’s nucleus has Seyfert-like activity.

• NGC 4151Narrower topic: NGC 4151 became a key example of the class Carl Seyfert defined in 1943.

• Low-ionization nuclear emission-line regionCompared with: Seyfert nuclei typically show stronger high-ionization emission than LINERs.

• NGC 5548Narrower topic: NGC 5548 belongs to this class of active galaxies.

• Magellanic spiralCompared with: Nuclear activity is a different classification feature from the bar-and-arm morphology defining this type.

• Messier 106Narrower topic: Messier 106 is classified as a Seyfert galaxy because its nucleus shows strong activity.

• Sculptor GalaxyCompared with: NGC 253's central activity is powered mainly by star formation, not an active nucleus.
