NGC 2962 is alenticular galaxy in the constellationHydra. The galaxy lies about 110 millionlight years away from Earth, which means, given its apparent dimensions, that NGC 2962 is approximately 90,000 light years across.[1] It was discovered byAlbert Marth on December 10, 1864.[3]
NGC 2962 is lenticular galaxy with two bars without a box shapedbulge.[4] The galaxy also has two rings, an inner ring with major axis 0.93 arcminutes long and an outer ring with major axis 2.13 arcminutes long.[5] The galaxy features a hydrogen disk, visible inHI, exteding well beyond the optical radius of the galaxy.[6]
The outer ring of NGC 2962 has low surface brightness and is created by tightly wound spiral arms which overlap while there are faint connections with the central region. There is no spiral pattern in the brighter, inner region of the galaxy.[7] The outer ring is better visible inultraviolet than the inner ring and contains about 5–8% of the stellar mass of the galaxy.[8] Ultraviolet imaging byGALEX shows it is bluer than the rest of the galaxy and has spiral arms emerging from it.[9] The ring corotates with the rest of the galaxy.[10]
The galaxy has probably accreted gas from a companion galaxy, which has led to renewed star formation activity in the nucleus.[8]
Onesupernova has been observed in NGC 2962, SN 1995D. The supernova was discovered byReiki Kushida in CCD images on 10 February 1995 at an apparent magnitude of 14.0, lying 11 arcseconds east and 90.5 arcseconds to the south of the centre of the galaxy.[11] The galaxy was identified as atype Ia supernova about a week before maximum.[12][13][14]
NGC 2962 is the foremost galaxy of the NGC 2962 Group or LGG 178. Other members of the group includeNGC 2966 and UGC 5107.[15][16] A hydrogen bridge has been found to connect NGC 2962 with gas rich galaxy SDSS J094056.3+050240.5, lying 8 arcminutes away.[6]
