Radial velocities and stellar population properties of 56 MATLAS dwarf galaxies observed with MUSE
Nick Heesters, Oliver Müller, Francine R. Marleau +6
Dwarf galaxies have been extensively studied in the Local Group, in nearby groups, and selected clusters, giving us a robust picture of their global stellar and dynamical propertie…
A too-many dwarf satellite galaxies problem in the MATLAS low-to-moderate density fields
Kosuke Jamie Kanehisa, Marcel S. Pawlowski, Nick Heesters +1
Dwarf galaxy abundances can serve as discernment tests for models of structure formation. Previous small-scale tensions between observations and dark matter-only cosmological simul…
The phase-space distribution of the M81 satellite system
Oliver Müller, Nick Heesters, Marcel S. Pawlowski +3
The spatial distribution of dwarf galaxies around their host galaxies is a critical test for the standard model of cosmology because it probes the dynamics of dark matter halos and…
New dwarf galaxy candidates in the M106, NGC3521, and UGCA127 groups with the Hyper Suprime Camera
Oliver Müller, Helmut Jerjen, Salvatore Taibi +3
The local universe is still full of hidden dwarf galaxies to be discovered using deep imaging campaigns. Here we present the third paper in a series to search for low-surface brigh…
Galaxies OBserved as Low-luminosity Identified Nebulae (GOBLIN): a catalog of 43,000 high-probability dwarf galaxy candidates in the UNIONS survey
Nick Heesters, David Chemaly, Oliver Müller +9
The detection of low surface brightness galaxies beyond the Local Group poses significant observational challenges, yet these faint systems are fundamental to our understanding of…
UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey
Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
