The ultra-diffuse galaxies DF2 and DF4 in the NGC 1052 group share several unusual
properties: they both have large sizes, rich populations of overluminous and large globular …

ABSTRACT PHANGS-HST is an ultraviolet-optical imaging survey of 38 spiral galaxies
within∼ 20 Mpc. Combined with the PHANGS-ALMA, PHANGS-MUSE surveys and other …

The tip of the red giant branch has been used to measure distances to 500 nearby galaxies
with the Hubble Space Telescope (HST) which are available in the Color–Magnitude …

The standard cold dark matter plus cosmological constant model predicts that galaxies form
within dark-matter haloes, and that low-mass galaxies are more dark-matter dominated than …

We derive the stellar population parameters of 11 quiescent ultra-diffuse galaxies (UDGs)
from Keck/KCWI data. We supplement these with 14 literature UDGs, creating the largest …

The existence of long-lived galaxies lacking dark matter represents a challenge to our
understanding of how galaxies form. Here, we present evidence that explains the lack of …

The recent discovery of diffuse dwarf galaxies that are deficient in dark matter appears to
challenge the current paradigm of structure formation in our universe. We describe …

Faint extended elliptically shaped ultra-diffuse galaxies and slightly brighter and more
compact dwarf elliptical and lenticular stellar systems are common in galaxy clusters. Their …

It was recently proposed that the dark matter–deficient ultradiffuse galaxies DF2 and DF4 in
the NGC 1052 group could be the products of a" bullet dwarf" collision between two gas-rich …
