NGC 1369 is abarred lenticular galaxy located 59 million light years away[4] in constellation ofEridanus. The galaxy was discovered by astronomerJulius Schmidt on January 19, 1865,[5] and is a member of theFornax Cluster.[6] NGC 1369 is a host to asupermassive black hole with an estimated mass of 1.8 millionsolar masses.[7]

Surrounding NGC 1369 is a population of a least 11 knownglobular clusters.[8]

Physical characteristics

[edit]

In the disk of NGC 1369, there are two bright, diffusespiral arms which break of a relatively weak bar structure. These arms quickly fade in the diffuse outer disk.[9] Despite the presence of spiral arms, the galaxy is very red which actually makes NGC 1369 alenticular galaxy.[10] Also, the galaxy is devoid of atomic and molecular gas,[11] and does not show any indications of ionised-gas emission as a result ofstar formation. Observations in X-rays have shown that it is infalling in a transional region of the Fornax Cluster between the high and low-density regions of the cluster where the X-ray emission is still present. As a result,ram-pressure stripping would have acted to stop star formation once the galaxy entered into the cluster core,[12] causing it to transion from aspiral galaxy to alenticular galaxy.[11]
