We propose that the ultra-diffuse galaxy (UDG) population represents a set of satellite
galaxies born in∼ 1010− 1011 M⊙ haloes, similar to field dwarfs, which suffer a dramatic …

We present spatially resolved stellar kinematics of the well-studied ultra-diffuse galaxy
(UDG) Dragonfly 44, as determined from 25.3 hr of observations with the Keck Cosmic Web …

We study the formation of ultradiffuse galaxies (UDGs) using the cosmological
hydrodynamical simulation TNG50 of the Illustris-TNG suite. We define UDGs as dwarf …

We study the gas kinematics of a sample of six isolated gas-rich low surface brightness
galaxies, of the class called ultra-diffuse galaxies (UDGs). These galaxies have recently …

Recent advances in deep dedicated imaging surveys over the past decade have uncovered
a surprisingly large number of extremely faint low surface brightness galaxies with large …

Almost dark galaxies are objects that have eluded detection by traditional surveys such as
the Sloan Digital Sky Survey (SDSS). The low surface brightness of these galaxies (μ r (0)> …

Understanding the peculiar properties of ultra-diffuse galaxies (UDGs) via spectroscopic
analysis is a challenging task requiring very deep observations and exquisite data …

Abstract We present Hubble Space Telescope imaging of 14 gas-rich, low-surface-
brightness galaxies in the field at distances of 25–36 Mpc, with mean effective radii and g …

Distance determinations of extremely low-surface-brightness galaxies are expensive in
terms of spectroscopic time. Because of this, their distances are often inferred by associating …

We present a homogeneous catalog of 275 large (effective radius≳ 5 farcs 3) ultra-diffuse
galaxy (UDG) candidates lying within an≈ 290 square degree region surrounding the Coma …
