dwarf spheroidal galaxy

Recently, dwarf spheroidal galaxies have become key objects for the study of dark matter.

It is the fourth largest Local Group dwarf spheroidal galaxy.

This found that the horizontal branch stars, like other dwarf spheroidal galaxies were predominantly red.

It is classified as a dwarf spheroidal galaxy (dSph).

MB3 is a dwarf spheroidal galaxy discovered in 1997 and located about 10 million light-years away from the Earth.

Leo I is a dwarf spheroidal galaxy in the constellation Leo.

M110 is classified as either a dwarf spheroidal galaxy or simply a generic elliptical galaxy.

Parametrically, these clusters lie somewhere between a globular cluster and a dwarf spheroidal galaxy.

No neutral or molecular hydrogen has been detected in it, which is consistent with its classification as a dwarf spheroidal galaxy.

Cetus Dwarf is a dwarf spheroidal galaxy.

Still fainter elliptical-like galaxies, called dwarf spheroidal galaxies, appear to be genuinely distinct.

Dwarf spheroidal galaxies appear to be a distinct class: their properties are more similar to those of irregulars and late spiral-type galaxies.

Dwarf spheroidal galaxy (dSph)

The stream is thought to be the remains of a dwarf spheroidal galaxy that is in the process of merging with the Milky Way.

Since small dwarf ellipticals bear little resemblance to large ellipticals, they are often called dwarf spheroidal galaxies instead.

This raises the question of whether there is a correlation between a radial horizontal-branch gradient and the metallicity dispersion between dwarf spheroidal galaxies.

It is classified as a dwarf spheroidal galaxy (dSph) meaning that it has an approximately round shape with the half-light radius of about 130 pc.

The Antlia Dwarf, a 14.8 dwarf spheroidal galaxy that belongs to our Local Group of galaxies.

Andromeda III is a dwarf spheroidal galaxy about 2.44 million light-years away in the constellation Andromeda.

The first one known as Dwingeloo 2 is an irregular galaxy and the second MB 3 is likely a dwarf spheroidal galaxy.

Bootes III is an overdensity in the Milky Way's halo, which may be a disrupted dwarf spheroidal galaxy.

Antlia Dwarf is unusual among dwarf spheroidal galaxies in that it contains large amounts (as much as 7 x10 solar masses) of neutral atomic hydrogen.

These satellite galaxies, like the satellites of the Milky Way, tend to be older, gas-poor dwarf elliptical and dwarf spheroidal galaxies.

At higher energies, ground-based gamma-ray telescopes have set limits on the annihilation of dark matter in dwarf spheroidal galaxies and in clusters of galaxies.
