NGC 1527

NGC 1527 is a lenticular galaxy in the constellation of Horologium. Its velocity with respect to the cosmic microwave background is 1,178±17 km/s, which corresponds to a Hubble distance of 56.7 ± 4.1 Mly (17.37 ± 1.27 Mpc).[1] Additionally, 10 non-redshift measurements give a mean distance of 55.87 ± 3.62 Mly (17.130 ± 1.111 Mpc).[2] It was discovered by Scottish astronomer James Dunlop on 28 September 1826.[3]

NGC 1527 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4][5]

Galaxy group

edit

NGC 1527 is a member of a galaxy group known as HDC 257. The group contains at least 14 galaxies, including NGC 1433, NGC 1483, NGC 1487, NGC 1493, NGC 1494 [fr], NGC 1495 [fr], NGC 1510, NGC 1512, IC 1959 [fr], IC 2000 (galaxy) [fr], ESO 201-14 [d], and two others.[6][7]

Supernova

edit

One supernova has been observed in NGC 1527:

  • SN 2008ge (Type Iax, mag. 12.8) was discovered by The CHilean Automatic Supernova sEarch (CHASE) on 8 October 2008.[8][9][10] It reached magnitude 12.2, making it the brightest supernova of 2008.[11] It was initially classified as Type Ia, but later analysis concluded that it was Type Iax.[10]
