NGC 1097 (also known as Caldwell 67) is a
Four supernovae have been observed in NGC 1097: SN 1992bd (type II, mag. 15), SN 1999eu (type II-pec, mag. 19.7), SN 2003B (type II, mag. 17.6),[4] and SN 2023rve (type II, mag. 14).[5]
General information
NGC 1097 is also a
NGC 1097 has a supermassive black hole at its center, which is 140 million times the mass of the Sun.[6][7] Around the central black hole is a glowing ring of star-forming regions with a network of gas and dust that spirals from the ring to the black hole. An inflow of material toward the central bar of the galaxy causes new stars to be created in the ring. The ring is approximately 5,000 light-years in diameter, the spiral arms of the galaxy extend tens of thousands of light-years beyond the ring.[6]
NGC 1097 has two satellite galaxies, NGC 1097A and NGC 1097B. Dwarf elliptical galaxy NGC 1097A is the larger of the two. It is a peculiar elliptical galaxy that orbits 42,000 light-years from the center of NGC 1097. Dwarf galaxy NGC 1097B (5 x 106 solar masses), the outermost one, was discovered by its HI emission, and appears to be a typical dwarf irregular. Little else is known about it.
