We present a study of the central parts of the Sagittarius dwarf spheroidal galaxy (Sgr). We found a clear overdensity of Sgr's stars around M 54 (hereafter NS). NS is well represented by a King model ...

The stately and inclined spiral galaxy NGC 3511 is the subject of this NASA/ESA Hubble Space Telescope image. The galaxy is located 43 million light-years away in the constellation Crater (The Cup).

A new study of diffuse dwarf galaxies is challenging the prevailing galaxy formation model within the standard Cold Dark Matter (CDM) framework, leading to a proposed new model of dark matter. Under ...

In contrast, dwarf galaxies have often been underrepresented in such studies because of their low luminosity and the challenges associated with sparse sampling. However, the USTC research team has ...

A new study of diffuse dwarf galaxies is challenging the prevailing galaxy formation model within the standard Cold Dark Matter (CDM) framework, leading to a proposed new model of dark matter.

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe.

Spirals are only one of four major classifications for galaxies; the others are elliptical, irregular and peculiar ... These are called “dwarf elliptical galaxies” and are satellites of ...

the uncertainty about the number); one such galaxy is the Ursa Minor Dwarf Galaxy. It was discovered by A.G. Wilson at Lowell Observatory in 1955. The Ursa Minor Dwarf is a small galaxy ...
