A 10,000-solar-mass black hole in the nucleus of a bulgeless dwarf galaxy

Nature Astronomy, 2019
The motions of gas and stars in the nuclei of nearby galaxies have demonstrated that massive black holes are common1 and that their masses correlate with the stellar velocity dispersion σ★ of the bulge2–4.

Dwarf galaxies in Clusters

Astrophysics and Space Science, 2003
Dwarf and Low Surface Brightness (LSB) galaxies are the most numerous type of galaxies in the local Universe. However ubiquitous they are, their properties remain widely unexplored. Dwarf galaxies range from Ultra Compact Objects (UCO), Dwarf Ellipticals (dE), Dwarf Spheroidals (dSph) to Dwarf Irregulars (dIrr) and are generally of low surface ...

Dwarf Irregular Galaxies

2004
Dwarf irregular galaxies at optical wavelengths are small, faint and appear to be unstructured and irregular in shape. They are typically gas-rich, metal-poor systems, with varying levels of STAR FORMATION occurring in a haphazard manner across the ...

A supermassive black hole in an ultra-compact dwarf galaxy

Nature, 2014
Ultra-compact dwarf galaxies are among the densest stellar systems in the Universe. These systems have masses of up to 2 × 108 solar masses, but half-light radii of just 3–50 parsecs.
