NGC 1404 is an elliptical galaxy in the Southern constellation Eridanus. It was discovered on November 28, 1837, by the astronomer John Herschel.[5] Based on the tip of the red-giant branch distance indicator, it lies at a distance of approximately 60 million light-years from the Milky Way.[3] It is one of the brightest members of the Fornax Cluster.[6][7]

Characteristics

[edit]

As usual with most elliptical galaxies, NGC 1404 is rich in globular clusters, with a population of them that has been estimated to be around 725;[8] however it has been proposed it could have lost most of its globular clusters due to gravitational interactions with NGC 1399, the brightest galaxy of the Fornax Cluster.[9]

Studies using the X-ray telescope Chandra show how the ram-pressure stripping caused by the motion of NGC 1404 through Fornax' intracluster medium is stripping the galaxy of its hot gas,[10] leaving behind a large trail.[11]

Supernovae

[edit]

Two supernovae have been observed in NGC 1404:

  • SN 2007on (type Ia, mag. 14.9) was discovered by the TAROT collaboration on 5 November 2007.[12][13]
  • SN 2011iv (type Ia, mag. 12.8) was discovered by Stuart Parker on 2 December 2011.[14][15]
