Muriel Mussells Seyfert
Muriel E. Mussells Seyfert (born Muriel Elizabeth Mussells, February 3, 1909 – November 9, 1997) was an American astronomer best known for discovering a "ring nebulae" (planetary nebulae) in the Milky Way while working at the Harvard College Observatory in 1936 as a human computer. Early life Muriel was born on February 3, 1909, in Danvers, Massachusetts, the daughter of George and Stella Mussells. Scientific contributions Mussells Seyfert was employed as a human computer at the Harvard College Observatory. By examining photographic plates taken at Harvard’s astronomical station at Bloemfontain, South Africa, she discovered three new ring nebulae in the Milky Way galaxy in the mid-1930s. Artist After moving to Nashville, Tennessee with her husband, Muriel pursued painting and maintained her art studio in the observatory residence (which has since become known as Muriel’s Retreat in her honor). Two of her portraits, one of observatory namesake Arthur Dyer and another o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Keenan Seyfert
Carl Keenan Seyfert (February 11, 1911 – June 13, 1960) was an American astronomer. He is best known for his 1943 research paper on high-excitation line emission from the centers of some spiral galaxies, which are named Seyfert galaxy, Seyfert galaxies after him. Seyfert's Sextet, a group of galaxies, is also named after him. Biography Seyfert was born and raised in Cleveland, Cleveland, Ohio, then attended Harvard University, starting in 1929. He earned his B.S. and M.S. degrees in 1933, and his Ph.D. in astronomy in 1936. His thesis was "Studies of the External Galaxies", supervised by Harlow Shapley. The thesis dealt with colors and magnitudes of galaxy, galaxies. In 1935 Seyfert married astronomer Muriel Mussells Seyfert, Muriel Elizabeth Mussels, who was a former Harvard Computers, Harvard computer who made contributions to the study of ring nebulae. They had two children, daughter Gail Carol and son Carl Keenan Seyfert, Jr. In 1936 Seyfert joined the staff of the new McD ...

Seyfert's Sextet
Seyfert's Sextet is a group of galaxies about 190 million light-years away in the constellation Serpens. The group appears to contain six members, but one of the galaxies, NGC 6027d, is a background object and another "galaxy," NGC 6027e, is actually a part of the tail from galaxy NGC 6027. The gravitational interaction among these galaxies should continue for hundreds of millions of years. Ultimately, the galaxies will merge to form a single giant elliptical galaxy. Discovery The group was discovered by Carl Keenan Seyfert using photographic plates made at the Barnard Observatory of Vanderbilt University. When these results were first published in 1951, this group was the most compact group ever identified. Members See also * Wild's Triplet * Zwicky's Triplet * Robert's Quartet * Stephan's Quintet and NGC 7331 Group ( Also known as the ''Deer Lick Group'', about half a degree northeast of Stephan's Quintet) * Copeland Septet The Copeland Septet (also Copeland' ...

Seyfert Galaxies
Seyfert galaxies are one of the two largest groups of active galaxies, along with quasars. They have quasar-like nuclei (very luminous, distant and bright sources of electromagnetic radiation) with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, their host galaxies are clearly detectable. Seyfert galaxies account for about 10% of all galaxies and are some of the most intensely studied objects in astronomy, as they are thought to be powered by the same phenomena that occur in quasars, although they are closer and less luminous than quasars. These galaxies have supermassive black holes at their centers which are surrounded by accretion discs of in-falling material. The accretion discs are believed to be the source of the observed ultraviolet radiation. Ultraviolet emission and absorption lines provide the best diagnostics for the composition of the surrounding material. Seen in visible light, most Seyfert galaxies ...

Dyer Observatory
The Dyer Observatory, also known as the Arthur J. Dyer Observatory, is an astronomical observatory owned and operated by Vanderbilt University.

Dyer, who paid for the observatory's -wide dome, and houses a reflecting telescope named for astronomer Carl Seyfert. Today, the observatory primarily serves as a teaching tool; its mission is to interest the public in the fields of astronomy, science and engineering. The observatory was listed on the National Register of Historic Places on March 6, 2009. (78 pages, including historic photos, blueprints, maps, diagrams and 36 color photos) History Vanderbilt's first observatory was housed on the campus itself.
