Definition of Seyfert galaxy in English:

Seyfert galaxy

nounˈseɪfəːtˌsēfərt ˈɡaləksē

Astronomy

A galaxy of a type characterized by a bright compact core that shows strong infrared emission.
〔天文〕赛弗特星系
Example sentencesExamples
- The lines tend to be broader, indicating more rapid motions, if Seyfert galaxies are viewed nearly face-on.
- Another impressive observation is that many of these close associations occur along lines, sometimes on either side of a special galaxy, such as a Seyfert galaxy.
- Examples of groups consisting of a bright galaxy plus Seyfert galaxies and quasars in lines suggest a hierarchy of paired ejections; some of these are particularly impressive and are analysed to yield ejection velocities.
- Look here for a disturbing prediction that our Milky Way will evolve into a Seyfert galaxy.
Synonyms
star system, solar system, constellation, cluster, nebula

Origin

Named after Carl K. Seyfert (1911–60), American astronomer.
