A Host Galaxy Morphology Link between Quasiperiodic Eruptions and Tidal Disruption Events

The Astrophysical Journal
The physical processes that produce X-ray quasiperiodic eruptions (QPEs) recently discovered from the nuclei of several low-redshift galaxies are mysterious.

Ultradiffuse Galaxies—A Distinct Population? Dwarf Galaxies in the Coma Cluster and A262 from Deep u′–g′–r′ Wendelstein Imaging Data

The Astrophysical Journal Supplement Series
In this study, we compare the structural parameters of ultradiffuse galaxies (UDGs) to those of other dwarf galaxies and investigate whether UDGs form a distinct population.

Ultra-diffuse galaxies in the Kilo-Degree Survey with deep learning

Astronomy & Astrophysics
Ultra-diffuse galaxies (UDGs) are a subset of low-surface-brightness galaxies (LSBGs), showing mean effective surface brightness fainter than 24 mag arcsec−2 and a diffuse morphology, with effective radii larger than 1.5 kpc.

Fuzzy Galaxies or Cirrus? Decomposition of Galactic Cirrus in Deep Wide-field Images

The Astrophysical Journal
Diffuse Galactic cirrus, or diffuse Galactic light (DGL), can be a prominent component in the background of deep wide-field imaging surveys. The DGL provides unique insights into the physical and radiative properties of dust grains in our Milky Way, and ...

Systematically Measuring Ultra-Diffuse Galaxies. VIII. Misfits, Miscasts, and Miscreants

The Open Journal of Astrophysics
We re-examine the 7,070 candidate ultra-diffuse galaxies (UDGs) in the SMUDGes survey and provide classifications based on their visual morphology.

Candidate Dark Galaxy-2: Validation and Analysis of an Almost Dark Galaxy in the Perseus Cluster

The Astrophysical Journal Letters
Candidate Dark Galaxy-2 (CDG-2) is a potential dark galaxy consisting of four globular clusters (GCs) in the Perseus cluster, first identified in D. Li et al. through a sophisticated statistical method. The method searched for overdensities of GCs from a
