NGC 7329 is a large barred spiral galaxy located in the constellation Tucana. [1] NGC 7329 was discovered by British astronomer John Herschel in 1835. [2]

Contents

The luminosity class of NGC 7329 is II and it has a broad HI line. To date, 29 non-redshift measurements yield a distance of 44.662 ± 5.536 Mpc (~146 million ly), [3] which is within the Hubble distance range. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy. [4]

Discovery

This galaxy was discovered in 1835 by the English astronomer John Herschel using a 47.5 cm (18.7 in) optical telescope that used a mirror as the light-gathering element.

Supernovae

Two supernovae have been observed in NGC 7329: SN 2006bh and SN 2009iu.

SN 2006bh

This supernova was discovered on April 2, 2006, by South African amateur astronomer Berto Monard, in Pretoria. It was cateogorized as type Ia with a magnitude of 14.8. [5]

SN 2009iu

This supernova, categorized as type Ib with a magnitude of 15.5, was discovered on September 1, 2009, by the CHASE (Chilean Automatic Supernova Search) project, a project searching for supernovae visible from astronomical observatories in the southern hemisphere. [6]

NGC 7329 Group

NGC 7329 is a member of a group of galaxies that bears its name. The NGC 7329 group has at least 11 members. The other galaxies are NGC 7358, NGC 7408, NGC 7417, IC 5222, IC 5227, IC 5244, IC 5250, IC 5266, IC 5272 and ESO 109-32. [7] This group of galaxies also bears the designation LGG 462.
