== Description ==
IC 1182 was originally classified as a [[Seyfert galaxy|Seyfert]] type 2 galaxy but later, research proves, it is indeed an unusual and rare galaxy in some kind of merger event.<ref>{{Cite web |title=Object of the Week May 25, 2014 IC 1182 A Member of The Jet Set |url=https://www.deepskyforum.com/showth...k-May-25-2014-IC-1182-A-Member-of-The-Jet-Set |access-date=2024-04-30 |website=www.deepskyforum.com}}</ref> It presents a [[Astrophysical jet|jet]] that is extending out from the center in east direction comprising of [[Kinetic energy|kinetic material]].<ref name=":1">{{Cite web |last=information@eso.org |title=The VLT Records Faint Structures in Colliding Galaxies |url=https://www.eso.org/public/news/eso9834/ |access-date=2024-04-30 |website=www.eso.org |language=es}}</ref> There is a broad faint S-shaped plume and debris on the other side of the galaxy. Not to mention, IC 1182 radiates a lot of [[energy]] and expels a subsential amount of material at high [[velocity]] into depths of space. In its central region, clusters of [[O-type main-sequence star|O-type]] hot blue stars are present.<ref name=":1" />

== An ongoing merger? ==
IC 1182 shows high resolution broad and narrow band images and long slit [[spectroscopy]]. It reveals a distorted morphology with a heavily [[Interstellar cloud|obscured disk-link structure]] with several knots in its regions.<ref name=":2">{{Cite journal |last=Moles |first=M. |last2=Bettoni |first2=D. |last3=Fasano |first3=G. |last4=Kjærgaard |first4=P. |last5=Varela |first5=J. |last6=Milvang-Jensen |first6=B. |date=2004-05-01 |title=The peculiar galaxy IC 1182: An ongoing merger? |url=https://www.aanda.org/articles/aa/abs/2004/17/aa0295/aa0295.html |journal=Astronomy & Astrophysics |language=en |volume=418 |issue=2 |pages=495–507 |doi=10.1051/0004-6361:20034295 |issn=0004-6361}}</ref> Some of the [[Interstellar medium|galactic material]], in the form of two slender tails are detected beyond the main body of the [[galaxy]]. IC 1182 has [[Color index|color indices]] of an early type object which is significantly bluer than what is typical for the kind of galaxy.<ref name=":2" /> The [[Narrow-line region|narrow lines]] shows this galaxy is a [[Active galactic nucleus|powerful emitter]] which the knots in the central region and inside the tail emerging eastward from the galaxy are [[Luminous efficacy|luminous]] in H''α'' and have typical sizes of 1 kpc.<ref name=":2" />

Additionally, IC 1182 presents large quantities of neural [[hydrogen]] which its distance-independent ratio of hydrogen mass to optical luminosity is equal to 0.7 times the [[Solar radio emission|solar ratio]].<ref name=":3">{{Cite journal |last=Bothun |first=G.
