Serendipitous discovery of an almost-dark galaxy in the Virgo Cluster

Minh Ngoc Le, Ignacio Trujillo, Sergio Guerra Arencibia +9

Analogues of extreme Local Group galaxies with very low surface brightness and large effective radii must exist elsewhere, still hidden due to current detection limits. We report t…

LIGHTS. The Thin Encircling Stellar Stream of NGC 3938

Dennis Zaritsky, Jacob Nibauer, Giulia Golini +17

We present a stellar stream found in images of the nearby, nearly face-on, late-type galaxy, NGC 3938 obtained for the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) s…

Euclid preparation LXXIX. Using mock low surface brightness dwarf galaxies to probe Euclid Wide Survey detection capabilities

Euclid Collaboration, M. Urbano, P. -A. Duc +313

Local Universe dwarf galaxies can serve as both cosmological and mass assembly probes. Deep surveys have enabled the study of these objects down to the low surface brightness (LSB)…

Euclid: Early Release Observations -- Interplay between dwarf galaxies and their globular clusters in the Perseus galaxy cluster

T. Saifollahi, A. Lançon, Michele Cantiello +183

We present an analysis of globular clusters (GCs) of dwarf galaxies in the Perseus galaxy cluster to explore the relationship between dwarf galaxy properties and their GCs. Our foc…

LIGHTS. A robust technique to identify galaxy edges

Giulia Golini, Ignacio Trujillo, Dennis Zaritsky +19

The LIGHTS survey is imaging galaxies at a depth and spatial resolution comparable to what the Legacy Survey of Space and Time (LSST) will produce in 10 years (i.e., 31 mag/a…

Euclid: Star clusters in IC 342, NGC 2403, and Holmberg II

S. S. Larsen, A. M. N. Ferguson, J. M. Howell +156

We examine the star cluster populations in the three nearby galaxies IC 342, NGC 2403, and Holmberg II, observed as part of the Euclid Early Release Observations programme. Our mai…
