NGC 1404 is anelliptical galaxy in the SouthernconstellationEridanus. It was discovered on November 28, 1837, by the astronomerJohn Herschel.[5] Based on thetip of the red-giant branch distance indicator, it lies at a distance of approximately 60 millionlight-years from theMilky Way.[3] It is one of the brightest members of theFornax Cluster.[6][7]

Characteristics

[edit]

As usual with most elliptical galaxies, NGC 1404 is rich inglobular 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 withNGC 1399, thebrightest galaxy of the Fornax Cluster.[9]

Studies using theX-raytelescopeChandra show how theram-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]

Twosupernovae 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]
