Looking into the faintEst WIth MUSE (LEWIS): Exploring the nature of ultra-diffuse galaxies in the Hydra-I cluster. VI. A star-forming UDG in Hydra I: a rare UDG or a transition phase?

Luca Rossi, Chiara Buttitta, Goran Doll +21

This paper presents a detailed analysis of a gas-rich star-forming ultra-diffuse galaxy (UDG) as part of the ESO Large Programme 'Looking into the faintEst WIth MUSE (LEWIS)'. Amon…

Advancing the detection of low surface brightness galaxies. I. ATTILA: multi-tAsking deTecTIon tool for Lsb gAlaxies

E. Borsato, F. Fonzo, N. Bellucco +15

Context. Ultra-diffuse galaxies (UDGs) lie at the extreme end of the size-luminosity distribution of low surface-brightness (LSB) galaxies. Their detection and characterization req…

VST-SMASH: VST Survey of Mass Assembly and Structural Hierarchy I. Survey presentation and deep photometry of IC 5332: tracing the mass assembly in the challenging faintest-end regime

R. Ragusa, C. Tortora, L. Hunt +9

Understanding the formation and evolution of late type galaxies (LTG) requires deep imaging for tracing the faintest stellar components in their outskirts. Despite their crucial ro…

Intracluster globular clusters as tracers of the mass assembly of the Hydra I galaxy cluster

Felipe S. Lohmann, Magda Arnaboldi, Michael Hilker +7

In galaxy clusters, hierarchical assembly predicts the formation of stellar substructures and intracluster light (ICL), a diffuse stellar component tracing the global cluster poten…

Stellar halos of bright central galaxies II: Scaling relations, colors and metallicity evolution with redshift

Emanuele Contini, Marilena Spavone, Rossella Ragusa +2

We study the formation and evolution of stellar halos (SHs) around bright central galaxies (BCGs), focusing on their scaling relations, colors, and metallicities across cosmic time…

The link between galaxy merger, radio jet expansion and molecular outflow in the ULIRG IRAS 00183-7111

Ilaria Ruffa, Marilena Spavone, Enrichetta Iodice +8

The ultraluminous infrared galaxy (ULIRG) IRAS 00183-7111 () is one of the three ULIRGs that are currently known to host an active galactic nucleus (AGN) with small-scale…
