dwarf elliptical galaxy

The galaxy is surrounded by many dwarf elliptical galaxies also located within the cluster.

M110 contains some dust and hints of recent star formation, which is unusual for dwarf elliptical galaxies in general.

Dwarf elliptical galaxies sometimes have pointlike nuclei that are also not well described by Sérsic's law.

NGC 4121 is a dwarf elliptical galaxy in the constellation Draco.

Dwarf elliptical galaxies, or dEs, are elliptical galaxies that are much smaller than others.

Or the satellite could dive in to the primary (e.g. Sagittarius Dwarf Elliptical Galaxy).

Dwarf elliptical galaxies have properties that are intermediate between those of regular elliptical galaxies and globular clusters.

The dwarf elliptical galaxies in Coma have their own, internal, velocity dispersion for their stars, which is a σ 80 km/s, typically.

Unlike most dwarf elliptical galaxies, NGC 185 contains young stellar clusters, and star formation proceeded at a low rate until the recent past.

The smallest, the Dwarf elliptical galaxies, may be no larger than a typical globular cluster, but contain a considerable amount of dark matter not present in clusters.

Elliptical galaxy: dwarf elliptical galaxy (dE)

It is suggested that dwarf spiral galaxies can transform into dwarf elliptical galaxies, expecially in dense cluster environments.

NGC 3109 is believed to be tidally interacting with the dwarf elliptical galaxy, Antlia Dwarf.

Among them are M54 and Omega Centauri, the former being the core of Sagittarius Dwarf Elliptical Galaxy.

Messier 32 (also known as NGC 221 and Le Gentil) is a dwarf elliptical galaxy about 2.65 million light-years away in the constellation Andromeda.

The Ursa Minor Dwarf dwarf elliptical galaxy was discovered by A.G. Wilson of the Lowell Observatory in 1954.

The Sagittarius Stream of the Sagittarius Dwarf Elliptical Galaxy (SagDEG) dominates the Field.

It had some success explaining galactic scale features, such as rotational velocity curves of elliptical galaxies, and dwarf elliptical galaxies, but did not successfully explain galaxy cluster gravitational lensing.

It does appear clear that globular clusters are significantly different from dwarf elliptical galaxies and were formed as part of the star formation of the parent galaxy rather than as a separate galaxy.

Observations by Hubble's Advanced Camera for Surveys spotted 29 dwarf elliptical galaxies in the Perseus Cluster, located 250 million light-years away and one of the closest galaxy clusters to Earth.

It is theorized that these are the cores of nucleated dwarf elliptical galaxies, that have been stripped of gas and outlying stars by tidal interactions, travelling through the hearts of rich clusters.

In contrast, dwarf elliptical galaxies, dwarf irregular galaxies, and the dwarf versions of Magellanic type galaxies (which may be considered transitory between spiral and irregular in terms of morphology) are very common.

While similar to dwarf elliptical galaxies in appearance and properties such as little to no gas or dust or recent star formation, they are approximately spheroidal in shape, generally lower luminosity, and are recognized only as satellite galaxies in the Local Group.

The Antlia Dwarf is classified alternatively as a dwarf elliptical galaxy of type dE3.5, or either as a dwarf spheroidal galaxy (dSph) or as a transitional galaxy from spheroidal to irregular types (dSph/Irr).

A search for a stellar stream from the Sagittarius Dwarf Elliptical Galaxy - which is currently merging with the Milky Way - in the vicinity of the sun yielded a null result, which helps constrain the shape of the Milky Way's dark halo.
