Discovery of a low surface brightness galaxy in the Zone of Avoidance using VVVX Deepstack imaging

J. L. Nilo-Castellón, L. Baravalle, D. Minniti +12

We report the discovery of VVVX J080705.96-273823.6, the first low-surface-brightness galaxy candidate identified in the Zone of Avoidance by the VISTA Variables in the Via Lactea…

Exploring the stellar streams and satellites around the giant low surface brightness galaxy Malin 1

Roy O. E. Bustos-Espinoza, Matias Blaña, Gaspar Galaz +7

Context. Giant Low Surface Brightness galaxies, such as Malin 1, host extended discs exceeding 100 kpc. Their formation and evolution remain debated, with interactions with satelli…

The Next Generation Fornax Survey (NGFS).VIII. A Support Vector Machine Approach for Disentangling Globular Clusters from other Sources

Yasna Ordenes-Briceño, Thomas H. Puzia, Paul Eigenthaler +8

Wide-field, multi-band surveys now detect millions of unresolved sources in nearby galaxy clusters, yet separating globular clusters (GCs) from foreground stars and background gala…

Formation of A Nuclear Star Cluster Through A Merger Event In The Low Surface Brightness Galaxy AGC 223218

Tian-Wen Cao, Zi-Qi Chen, Zi-Jian Li +8

We present the properties of the nuclear star cluster (NSC) in the low surface brightness galaxy AGC 223218. The disk of the galaxy can be modeled using two Srsic co…

The formation and evolution of Supermassive disks in IllustrisTNG

Diego Pallero, Gaspar Galaz, Patricia B. Tissera +4

Supermassive disks are outstanding galaxies whose formation and evolution are still poorly understood. They comprise a large variety of objects, ranging from large, low-surface-bri…

Diving into dangerous tides: The impact of galaxy cluster tidal environments on satellite galaxy mass densities

Matias Blaña, Thomas H. Puzia, Yasna Ordenes-Briceño +8

Satellite galaxies endure powerful environmental tidal forces that drive mass stripping of their outer regions. Consequently, satellites located in central regions of galaxy cluste…
