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…
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…
MUSE observations of dwarf galaxies and a stellar stream in the M83 group
Oliver Müller, Marina Rejkuba, Katja Fahrion +8
Spectroscopy for faint dwarf galaxies outside of our own Local Group is challenging. Here, we present MUSE spectroscopy to study the properties of four known dwarf satellites and o…
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…
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,…
Dwarf Galaxies in the MATLAS Survey: The satellite system of NGC474 under scrutiny with MUSE
Oliver Müller, Francine R. Marleau, Nick Heesters +12
A recent study of the distribution of dwarf galaxies in the MATLAS sample in galaxy groups revealed an excess of flattened satellite structures, reminiscent of the co-rotating plan…
Lopsided distribution of MATLAS and ELVES dwarf satellite systems around isolated host galaxies
Nick Heesters, Helmut Jerjen, Oliver Müller +2
The properties of satellite dwarf galaxies pose important empirical constraints to verify cosmological models on galaxy scales. Their phase-space correlations, in particular, offer…
The satellite galaxy plane of NGC 4490 in light of ΛCDM - Sparsity of similarly extreme analogs and a possible role of satellite pairs
Marcel S. Pawlowski, Oliver Müller, Salvatore Taibi +3
The galaxy system around NGC4490 was recently highlighted to display a flattened, kinematically correlated structure reminiscent of satellite galaxy planes around other hosts. Sinc…
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…
The creation of a massive UCD by tidal threshing from NGC 936
Sanjaya Paudel, Pierre-Alain Duc, Sungsoon Lim +9
We study a compact nucleus embedded in an early-type dwarf galaxy, MATLAS-167, which is in the process of disruption by the tidal force of the neighboring giant S0 galaxy, NGC 936,…
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…
Is there a dwarf galaxy satellite-of-satellite problem in CDM?
Oliver Müller, Nick Heesters, Helmut Jerjen +2
Dark matter clusters on all scales, therefore it is expected that even substructure should host its own substructure. Using the Extragalactic Distance Database, we searched for dwa…
Flattened structures of dwarf satellites around massive host galaxies in the MATLAS low-to-moderate density fields
N. Heesters, R. Habas, F. R. Marleau +6
It was first observed in the 1970s that the dwarf galaxies surrounding our Milky Way, so-called satellites, appear to be arranged in a thin, vast plane. Similar discoveries have be…
