NGC 3341 is a peculiar galaxy located in the constellation of Sextans. It is located 415 million light years away from Earth and has a diameter of 170,000 light years. [1] It was discovered by Albert Marth on March 22, 1865, who described the object as "very faint and small". [2] The galaxy is classified a minor galaxy merger system, with two known companions revealed as offset active galactic nuclei (AGN).

Characteristics

NGC 3341 is classified as a giant disk galaxy located at redshift 0.027. It has a magnitude of MB = -20.3 with a mass of ≈ 1 x 1011 MΘ. [3] The galaxy has two smaller companions of low mass located north from the galaxy with an estimated distance of 5.1 and 8.4 kiloparsecs respectively. [3]

Further observations by astronomers, classified the two offset nuclei of NGC 3341 as dwarf ellipticals or budge remnants of spiral galaxies, whose disk structures were tidal stripped as they coalesced into the larger primary galaxy. [4] According to observations made by Foord and his colleagues, they found the primary nucleus of NGC 3341 has a 0.5-8 keV flux with luminosity of 3.63+0.07-0.05 in harmony with a rest-frame luminosity of 8.54+0.41-0.33 x 1041 erg s-1. The secondary nucleus on the other hand, has an observed 0.5-8 keV flux of 2.7+0.6-0.8 x 10-15 erg s-1 cm-2 s-1. Despite the primary nucleus having an X-ray luminosity of LX > 1 x 1041 erg s-1, the second doesn't. [5]

What is more stranger about the nuclei of NGC 3341, is both of them have different classifications. One is classified a Seyfert type II while the other is a LINER containing weak emission lines. However, the primary nucleus in NGC 3341 contains an emission-line spectrum. Based on the optical spectra of the two nuclei, it is suggested NGC 3341 might well be a dual AGN or a triple AGN system. [4] But because the secondary nucleus never met the X-ray luminosity standards, the merger system of NGC 3341 actually contains a sole AGN. [6]

An active galactic nucleus (AGN) is 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. Such excess, non-stellar emissions have been observed in the radio, microwave, infrared, optical, ultra-violet, X-ray and gamma ray wavebands. A galaxy hosting an AGN is called an active galaxy. The non-stellar radiation from an AGN is theorized to result from the accretion of matter by a supermassive black hole at the center of its host galaxy.

The Black Eye Galaxy is a relatively isolated spiral galaxy 17 million light-years away in the mildly northern constellation of Coma Berenices. It was discovered by Edward Pigott in March 1779, and independently by Johann Elert Bode in April of the same year, as well as by Charles Messier the next year. A dark band of absorbing dust partially in front of its bright nucleus gave rise to its nicknames of the "Black Eye", "Evil Eye", or "Sleeping Beauty" galaxy. M64 is well known among amateur astronomers due to its form in small telescopes and visibility across inhabited latitudes.
