Are Gas-rich Ultra-diffuse Galaxies and Field Dwarfs Distinct?

The Astrophysical Journal
We explore the differences in gas-rich field ultra-diffuse galaxies (UDGs) and diffuse classical dwarf galaxies using an extensive atomic gas (H I ) follow-up survey of optically selected UDG candidates from the Systematically Measuring Ultra-diffuse ...

VST-SMASH: VST Survey of Mass Assembly and Structural Hierarchy

Astronomy & Astrophysics
Context. Understanding the formation and evolution of late-type galaxies requires deep imaging for tracing the faintest stellar components in their outskirts (i.e. accreted material, diffuse halos, and tidal streams).

Ultradiffuse Galaxies in the EAGLE Simulation

The Astrophysical Journal
We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultradiffuse galaxies (UDGs). We identify 181 UDGs at z = 0 and find their properties are consistent with observations.

An Accreting Supermassive Black Hole Buried in a Faint Dwarf Galaxy

The Astrophysical Journal Letters
In the last decade, there have been several discoveries of active galactic nuclei (AGN) in dwarf galaxies including an AGN in an ultracompact dwarf galaxy with a black hole mass >10 ^6 M _⊙ .

Formation of a Nuclear Star Cluster through a Merger Event in the Low-surface-brightness Galaxy AGC 223218

The Astrophysical Journal
We present the properties of a nuclear star cluster (NSC) in the low-surface-brightness galaxy AGC 223218. The disk of the galaxy can be modeled using two Sérsic components with distinct central positions: one representing the inner bright disk and the ...
