NGC 3115 (also called the Spindle Galaxy or Caldwell 53) is a field lenticular (S0) galaxy in the constellation Sextans. The galaxy was discovered by William Herschel on February 22, 1787. [4][5] At about 32 million light-years away from Earth, it is …

NGC 3115，也稱為 紡錘星系 或 科德韋爾53，是位於 六分儀座 的一個 透鏡星系。 這個星系是 威廉·赫歇爾 在1787年2月22日發現的 [3]，與 地球 的距離大約是3,200萬 光年，它的大小數倍於 銀河系。

NGC 3115 is a Elliptical/Spiral Galaxy in the Sextans constellation. NGC 3115 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

2011年7月27日 · NGC 3115 is located about 32 million light years from Earth and is classified as a so-called lenticular galaxy because it contains a disk and a central bulge of stars, but without a detectable spiral pattern.

2019年3月28日 · The nearby galaxy NGC 3115 contains a known radio-emitting, low-luminosity active galactic nucleus (AGN), and was recently claimed to host a candidate AGN displaced 14.3 pc from the galaxy's optical photocenter. Our goal is to understand whether this represents a single offset AGN, an AGN in orbit around a central black hole, or something else.

NGC 3115 is a Lenticular Galaxy located in the constellation of Sextans in the equatorial region. NGC 3115's distance from Earth is 33,525,614.06 light years. NGC 3115 is called NGC 3115 in the New General Catalogue (NGC).

2021年4月10日 · Most likely, NGC 3115 formed from a gas-rich merger, forming the bulge and thick disc. Then through processes of accretion and feedback, a thin disc developed and an AGN was activated, which quenched star formation due to the influx of hot gas that prevented cooling.

The galaxy NGC 3115 is shown here in a composite image of data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope (VLT). Using the Chandra image, the flow of hot gas toward the supermassive black hole in the center of this galaxy has been imaged.

The black hole at the center of the galaxy NGC 3115 is one of the largest and most-massive yet discovered: It probably weighs in at around one billion times the mass of the Sun. The galaxy itself is several times larger than the Milky Way. Its stars are mostly old, and there is little gas to give birth to new stars.
