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 brightnesses and large effective radii must exist elsewhere, still hidden due to current detection limits. We report…
The explosive growth of the Messier 74 galaxy. A galaxy doubling its size in less than a Gigayear
Ignacio Ruiz Cejudo, Ignacio Trujillo, Sergio Guerra Arencibia +3
Galaxy formation models predict that galaxies grow inside-out, becoming larger over time. While observations broadly support this paradigm, the nature and timescales of this growth…
Deep imaging of the very isolated dwarf galaxy NGC6789
Ignacio Trujillo, Sergio Guerra Arencibia, Ignacio Ruiz Cejudo +3
We present deep optical imaging of the extremely isolated dwarf galaxy NGC 6789, obtained with the new 2-meter Two-meter Twin Telescope (TTT3) at Teide Observatory. Despite its loc…
Deep imaging of the galaxy Malin 2 shows new faint structures and a candidate satellite dwarf galaxy
Junais, Ignacio Ruiz Cejudo, Sergio Guerra Arencibia +5
Giant Low Surface Brightness (GLSB) galaxies are extreme disk systems with exceptionally large sizes and low stellar densities. Their formation and evolution remain poorly constrai…
