NGC 3191 (also known as NGC 3192) is a barred spiral galaxy in the constellation Ursa Major. It was discovered on 5 February 1788 by William Herschel. It is located at a distance of about 400 million light years from Earth, which, given its apparent dimensions, means that NGC 3191 is about 115,000 light years across.

NGC 3191 （又名 NGC 3192）是一个位于 大熊座 的 棒旋星系，距离地球4亿 光年，直径11.5万光年。 NGC 3191与其西边1.3弧分的星系形成 交互作用星系，两星系间形成蓝色的潮汐桥 [2]。 研究人员在NGC 3191中发现了 超新星 SN 1988B 和 SN 2017egm。 SN 1988B出现在星系中心偏北10 角秒 处。 SN 2017egm在2017年5月23日由 盖亚任务 发现，是一颗 Ia型超新星 [3][4][5]。 ^ 跳转到： 1.0 1.1 1.2 1.3 1.4 1.5 1.6 NASA/IPAC Extragalactic Database.

2017年8月13日 · Here we present an integral-field study of the massive, high-metallicity spiral NGC 3191, the host of SN 2017egm, the closest SLSN Type I to date. We use data from PMAS/CAHA and the public MaNGA survey to shed light on the properties of the SLSN site and the origin of star-formation in this non-starburst spiral galaxy.

At redshift z = 0.03, the recently discovered SN 2017egm is the nearest Type I superluminous supernova (SLSN) to date and first near the center of a massive spiral galaxy (NGC 3191). Using SDSS spectra of NGC 3191, we find a metallicity ∼2 {Z} ⊙ at the nucleus and ∼1.3 {Z} ⊙ for a star-forming region at a radial offset similar to SN ...

2017年8月2日 · Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I occurring in a "normal" spiral galaxy (NGC 3191) in terms of stellar mass (several times 10^10 M_sun) and metallicity (roughly Solar).

2017年8月10日 · At redshift z = 0.03, the recently discovered SN 2017egm is the nearest Type I superluminous supernova (SLSN) to date and first near the center of a massive spiral galaxy (NGC 3191). Using SDSS spectra of NGC 3191, we find a metallicity ∼2 at the nucleus and ∼1.3 for a star-forming region at a radial offset similar to SN 2017egm.

2018年1月23日 · Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I occurring in a "normal" spiral galaxy (NGC 3191) in terms of stellar mass (several times 10 10 M⊙) and metallicity (roughly solar).
