Minkowski's object
  بر‌آخت ِ مینکوفسکی   
barâxt-e Minkowski

Fr.: objet de Minkowski   

A peculiar blue object near the → elliptical galaxy NGC 541 in the → galaxy cluster Abell 194.

1, 2, 3, 4, 5, 6) barâxt; 7) kondâr

Fr.: objet   

1) General: Anything that is visible or tangible.
2) Physics: A collection of masses, taken to be one.
3) Optics: The collection of points that acts as a source of light rays for an optical system.
4) Astro.: A general designation for material bodies studied in this science.
5) Math.: Anything that could be formally defined, and with which one may do deductive reasoning and mathematical proofs. → mathematical object
6) Computer science: A free standing chunk of code that defines the properties of some thing.
7) Grammar: In English grammar, a noun, noun phrase, or pronoun that is affected by the action of a verb (a direct object or an indirect object) or that completes the meaning of a preposition (the object of a preposition).

From M.L. objectum "thing thrown down or put before" (the mind or sight), neutral of objectus, p.p. of obicere "to present, oppose, cast in the way of," from ob "against" + jacere "to throw," from PIE base *ye- "to do" (cf. Gk. iemi, ienai "to send, throw," Hitt. ijami "I make").

Barâxt "thing drawn against, before" from bar- + âxt. The prefix bar- "on; upon; against; before; at; in," from Mid.Pers. abar, O.Pers. upariy "above; over, upon, according to," Av. upairi "above, over" (upairi.zəma- "located above the earth"), cf. Gk. hyper- "over, above," L. super-, O.H.G. ubir "over;" PIE base *uper "over".
The second component âxt, contraction of âxté, p.p. of âxtan, variants âhixtan, âhiz- "to draw (a sword)," âhanjidan "to draw up, pull, extract," Mid.Pers. âhixtan, âhanjitan "to draw out, pull up, extract," Av. θanj- "to draw, pull, drive;" Proto-Iranian *θanj-.
