NGC 1042 is aspiral galaxy located in theconstellationCetus. It was discovered on 10 November 1885 byAmerican astronomerLewis Swift.[2] The galaxy has an apparent magnitude of 14.0.

NGC 1042 is a low-luminosityactive galaxy.[3][4] Furthermore, its luminosity class is III–IV and it has a broadHI line.[5] It is known that NGC 1042 also hosts an intermediate-massblack hole in its center.[6]

NGC 1042 contains an ultraluminousX-ray source called NGC 1042 ULX1.[7]

Morphology

[edit]

NGC 1042 is a late-type galaxy, classified as type SAB(rs)cd.[8] It has a bulgeless structure withspiral arms consisting of twosymmetric arms located in the inner side with ceaseless long outer arms, with an Arm Class 9 classification.[9] The spiral galaxy type of NGC 1042 is a mystery; some astronomers classified it abarred spiral galaxy based onellipse fitting via B- and H-band images,[10] while others classified it anunbarred spiral galaxy.[11][12] Further evidence by them suggests, the inner arms of NGC 1042 are curved with a bar-like structure that is mistaken as a bar.[13][4]

Nearby galaxies

[edit]

NGC 1042 appears near thespiral galaxyNGC 1035 in the sky, with both having similarredshifts. The two objects may therefore be physically associated with each other.[14] In additional, NGC 1042 is also a member of theNGC 1052 group.[15] It is shown to be the only galaxy with a large gas reservoir, indicating it was stripped ofgas during a pastinteraction with NGC 1052.[16]
