NGC 4102

April 06, 2023

NGC 4102 is an intermediate[9] barred spiral galaxy located in the northern constellation of Ursa Major. It is visible in a small telescope and has an apparent visual magnitude of 11.2.[7] The galaxy was discovered April 12, 1789 by William Herschel. J. L. E. Dreyer described it as "bright, pretty small, round, brighter middle and bright nucleus".[11] This galaxy is located at a distance of 60[5] million light years and is receding with a heliocentric radial velocity of 837 km/s.[4] It is a member of the Ursa Major group of galaxies.[6]

The morphological class of NGC 4102 is SABab[3] or SAB(s)b?,[10] which is a spiral galaxy with a bar-like feature around the core (SAB), no inner ring structure (s), and moderately tightly-wound spiral arms ('ab' or 'b'). However, the bar in this galaxy is considered particularly small for galaxies of this class.[10] The galactic plane is inclined at an angle of 56°±2° to the line of sight from the Earth.[12] NGC 4102 has a region of intense star formation in the nuclear region, known as a starburst region.[6] This volume is 1,000 ly (310 pc) in diameter containing some 3 billion solar masses.[13] An outflow of hydrogen has been detected, extending outward to the northwest as far as 6.3 kpc (21 kly) from the nucleus.[14]

The core of NHC 4102 is almost certainly an active galactic nucleus (AGN),[15] which indicates it has a supermassive black hole (SMBH) that is generating energy by accreting material.[16] It is an X-ray source with a spectrum similar to a Seyfert 2 galaxy.[15] This type of AGN is known as a Type-2 LINER, or low-ionization nuclear emission-line region. This is due to a core that is obscured by intervening dusty materials and/or the SMBH is accreting material in an inefficient manner. The bolometric luminosity of the active nucleus is ~7×1043 erg·s−1.[16]

One supernova has been observed in NGC 4102: SN 1975E (type unknown, mag. 16.7).[17]
