Spiral galaxy in the constellation Cetus
NGC 1042 is aspiral galaxy located in theconstellation Cetus . 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]
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]
NGC 1042 appears near thespiral galaxy NGC 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]
