HST Proper Motions of Andromeda V and VI
Dana I. Casetti-Dinescu, Marcel S. Pawlowski, Terrence M. Girard +3
We measure the absolute proper motions of Andromeda V (And V) and Andromeda VI/Pegasus (And VI) dwarf galaxies, satellites of M31 located near its galactic plane. And VI is located…
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…
Andromeda's asymmetric satellite system as a challenge to cold dark matter cosmology
Kosuke Jamie Kanehisa, Marcel S. Pawlowski, Noam Libeskind
The Andromeda galaxy is surrounded by a strikingly asymmetrical distribution of satellite dwarf galaxies aligned towards the Milky Way. The standard model of cosmology predicts tha…
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…
HST Proper Motion of Andromeda III: Another Satellite Co-orbiting The M31 Satellite Plane
Dana I. Casetti-Dinescu, Marcel S. Pawlowski, Terrence M. Girard +5
We measure the absolute proper motion of Andromeda III using ACS/WFC and WFPC2 exposures spanning an unprecedented 22-year time baseline. The WFPC2 exposures have been processed us…
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 imprint of galaxy mergers on satellite planes in a cosmological context
Kosuke Jamie Kanehisa, Marcel S. Pawlowski, Oliver Müller
Flattened and kinematically correlated planes of dwarf satellite galaxies have been observed in the Local Volume. The slinging out of satellites during host galaxy mergers has been…
Classifying the satellite plane membership of Centaurus A's dwarf galaxies using orbital alignment constraints
Kosuke Jamie Kanehisa, Marcel S. Pawlowski, Oliver Müller +1
The flattened, possibly co-rotating plane of satellite galaxies around Centaurus A, if more than a fortuitous alignment, adds to the pre-existing tension between the well-studied M…
The intervelocity of galaxy pairs in CDM -- The observed velocity peak at ~130 km/s is not unique to MOND
Marcel S. Pawlowski, Kosuke Jamie Kanehisa, Salvatore Taibi +1
Observational studies of pairs of galaxies have uncovered that their differential line-of-sight velocities indicate the presence of a peak in their three-dimensional intervelocity…
