An LBT view of the co-rotating group of galaxies around NGC 2750: Deep imaging and new satellite candidates
S. Taibi, M. S. Pawlowski, O. Müller +6
Some galaxies such as the Milky Way and Andromeda display coherently rotating satellite planes, posing tensions with cosmological simulations. NGC 2750 has emerged as an additional…
The effect of measurement uncertainties on the inferred stability of planes of satellite galaxies
Prem Kumar, Marcel S. Pawlowski, Kosuke Jamie Kanehisa +3
Observations have revealed that the MW, Andromeda, Centaurus A (and potentially other galaxies) host spatially thin and kinematically coherent planes of satellites. Such structures…
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,…
