Testing a proposed "planarity" tool for studying satellite systems: On the alleged consistency of Milky Way satellite galaxy planes with CDM

Marcel S. Pawlowski, Mariana P. Júlio, Kosuke Jamie Kanehisa +1

The existence of planes of satellite galaxies has been identified as a long-standing challenge to CDM cosmology, due to the rarity of satellite systems in cosmological simulatio…

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…

Simulations of cluster ultra-diffuse galaxies in MOND

Srikanth T. Nagesh, Jonathan Freundlich, Benoit Famaey +4

Ultra-diffuse galaxies (UDGs) in the Coma cluster have velocity dispersion profiles that are in full agreement with the predictions of Modified Newtonian Dynamics (MOND) in isolati…

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…

A too-many dwarf galaxy satellites problem in the M83 group

Oliver Müller, Marcel S. Pawlowski, Yves Revaz +4

Dwarf galaxies in groups of galaxies provide excellent test cases for models of structure formation. This led to a so-called small-scale crisis, including the famous missing satell…

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…
