NGC 4274 is a barred spiral galaxy located in the constellation Coma Berenices. It is located at a distance of circa 45 million light years from Earth, which, given its apparent dimensions, means that NGC 4274 is about 95,000 light years across. It was discovered by William Herschel in 1785.

Characteristics

NGC 4274 is characterised by its overlapping outer arms, forming a ring structure with apparent diameter 2.8′. The inner arms begin near the edge of the bulge and they are bright and dusty, with dust lanes that are more prominent at the near side. Outside the near-ring a set of fainter outer arms has been detected. [3] These outer arms also form a ring, with diameter 5.9′. A third rings exists near the nucleus. [4] The nuclear ring has semimajor axis 9", which corresponds to 680 parsec at that distance. [5]

The bar of the galaxy is 5 kpc long. [5] The galaxy features a nuclear bar that is almost perpendicular to the outer bar. [6] [7]

Supernova

One supernova has been observed in NGC 4274: SN 1999ev. It was a type II supernova, discovered by Tom Boles on 7 November 1999. It peaked at magnitude 15.2. [8]

Nearby galaxies

NGC 4274 is the foremost member of a galaxy group known as NGC 4274 group. Other members of the group are NGC 4173, NGC 4245, NGC 4251, NGC 4283, IC 3215, NGC 4310, and NGC 4314. [9] It is part of the Coma I Group which is part of the Virgo Supercluster. [10]

<span class="mw-page-title-main">NGC 4725</span> Galaxy in the constellation Coma Berenices

NGC 4725 is an intermediate barred spiral galaxy with a prominent ring structure, located in the northern constellation of Coma Berenices near the north galactic pole. It was discovered by German-born British astronomer William Herschel on April 6, 1785. The galaxy lies at a distance of approximately 40 megalight-years from the Milky Way. NGC 4725 is the brightest member of the Coma I Group of the Coma-Sculptor Cloud, although it is relatively isolated from the other members of this group. This galaxy is strongly disturbed and is interacting with neighboring spiral galaxy NGC 4747, with its spiral arms showing indications of warping. The pair have an angular separation of 24′, which corresponds to a projected linear separation of 370 kly. A tidal plume extends from NGC 4747 toward NGC 4725.

NGC 3344 is a relatively isolated barred spiral galaxy located 22.5 million light years away in the constellation Leo Minor. This galaxy belongs to the group known as the Leo spur, which is a branch of the Virgo Supercluster. NGC 3344 has the morphological classification (R)SAB(r)bc, which indicates it is a weakly barred spiral galaxy that exhibits rings and moderate to loosely wound spiral arms. There is both an inner and outer ring, with the prominent arms radiating outward from the inner ring and the slightly elliptical bar being situated inside. At the center of the bar is an HII nucleus with an angular diameter of about 3″. NGC 3344 hosted supernova SN 2012fh, which was shown to likely be a Type Ib or Type Ic.
