Search the designations of an object

This catalogue (table a101 in the database) presents the compilation of the designations of objects. In general, the designations are formed from an acronym of the catalogue where the source is described followed by a running number: For example, NGC 4486 means "the object number 4486 in the New General Catalogue". A given object may have several names. See a list of catalogues of galaxies from the NED knowledge database (Level 5).

The designations should comply several rules defined by the commission 5 of the IAU, and new acronyms should be declared to this commission. There are some variants between the coding of names between the various databases, Simbad and NED in particular. HyperLeda tries to use names as widely accepted as possible.

For most of the recent large surveys, the names are build from the acronym and from the position of the object on the sky (in general the J2000 equatorial coordinates). Note that the position must be "truncated" not "rounded".

Objects known by their lexical name

Many bright objects are known by a lexical name. These names are useful for some nearby large galaxies (Dwingeloo 1 and 2; Maffei 1 and 2, etc...). These names are given in the table below:
See also the list of named galaxies from the NED knowledge database (Level 5).

Description of the various fields in the catalogue

Field: design

Designation in a standardized spelling. The colon behing a galaxy designation means that this name is given to 2 (or more) objects. It may happen in particular for members of a pair or of a group of galaxies. The pair keeps the name given in the catalogue and the 2 objects members of the pair have the same name + the colon.

Field: flag

Not fully reliable name. In the past this name was given to another object of the database (wrong identification), and was corrected to its current affectation. There is a risk that some references in the literature use the ancient wrong identification. This name should be avoided.
Unreliable name. This name is associated with a different objects in different papers, and in particular between NED and HyperLeda. It should not be used.
Degenerated name. This name is given to more than one object (like maybe the members of a pair of galaxies). It should not be used.
