Dwarf galaxies in the MATLAS Survey: Hubble Space Telescope observations of nuclear star clusters

Mélina Poulain, Francine R. Marleau, Pierre-Alain Duc +8

In dwarf galaxies, nuclear star clusters (NSCs) are believed to primarily form from the migration and merger of globular clusters (GCs), with a possible contribution from in-situ s…

Low Surface Brightness structures from annotated deep CFHT images: effects of the host galaxy's properties and environment

Elisabeth Sola, Pierre-Alain Duc, Mathias Urbano +20

Hierarchical galactic evolution models predict that mergers drive galaxy growth, producing low surface brightness (LSB) tidal features that trace galaxies' late assembly. These fai…

Evidence of star cluster migration and merger in dwarf galaxies

Mélina Poulain, Rory Smith, Pierre-Alain Duc +8

Nuclear star clusters (NSCs) are the densest stellar systems in the Universe. They can be found at the center of all galaxy types, but tend to favor galaxies of intermediate stella…

Pearls on a string: Dark and bright galaxies on a strikingly straight and narrow filament

Maryam Arabsalmani, Sambit Roychowdhury, Benjamin Schneider +11

We identify a chain of galaxies along an almost straight line in the nearby Universe with a projected length of ~5 Mpc. The galaxies are distributed within projected distances of o…
