PGC 13809
emission-line galaxy of the Fornax Cluster
PGC 13809 is a spiral, almost edge-on galaxy in the constellation Fornax. It was discovered by the European Southern Observatory and it is a member of the Fornax Cluster.
PGC 13809 has a Hubble classification of Sc, indicating it is an unbarred spiral galaxy with loose spiral arms. It is also seen nearly edge-on, with an angle of about ≈80 degrees (≈80°). Its size on the night sky is 4.8' x 0.8', indicating a real size of about 90,000 light-years, so PGC 13809 is slightly smaller than the Milky Way. It is also one of the larger galaxies in the Fornax Cluster, a cluster of 200 galaxies. Its magnitude is 12.6.
With a redshift of 1838 km/s, it is one of the faster moving galaxies in the Fornax Cluster, but it is close to the central giant elliptical galaxy NGC 1399, so gravitational reaction is possible.
This brief starts where responsible research should: with the source description of “PGC 13809” as emission-line galaxy of the Fornax Cluster. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as emission-line galaxy of the Fornax Cluster. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 14, 2023. The linked authority identifier is Q15921515. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1838 and 1399.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
