The Cen A galaxy group: dynamical mass and missing baryons
Oliver Müller, Federico Lelli, Benoit Famaey +5
The nearby elliptical galaxy Cen A is surrounded by a flattened system of dwarf satellite galaxies with coherent motions. Using a novel Bayesian approach, we measure the mean rotat…
On the Effect of the Large Magellanic Cloud on the Orbital Poles of Milky Way Satellite Galaxies
Marcel S. Pawlowski, Pierre-Antoine Oria, Salvatore Taibi +2
The reflex motion and distortion of the Milky Way (MW) halo caused by the infall of a massive Large Magellanic Cloud (LMC) has been demonstrated to result in an excess of orbital p…
On the Co-Orbitation of Satellite Galaxies Along the Great Plane of Andromeda: NGC 147, NGC 185, and Expectations from Cosmological Simulations
Marcel S. Pawlowski, Sangmo Tony Sohn
Half of the satellite galaxies of Andromeda form a narrow plane termed the Great Plane of Andromeda (GPoA), and their line-of-sight velocities display correlation reminiscent of a…
The phantom dark matter halos of the Local Volume in the context of modified Newtonian dynamics
P. -A. Oria, B. Famaey, G. F. Thomas +8
We explore the predictions of Milgromian gravity (MOND) in the Local Universe by considering the distribution of the `phantom' dark matter (PDM) that would source the MOND gravitat…
The Baryonic Tully-Fisher Relation in the Local Group and the Equivalent Circular Velocity of Pressure Supported Dwarfs
Stacy McGaugh, Federico Lelli, Jim Schombert +4
We explore the Baryonic Tully-Fisher Relation in the Local Group. Rotationally supported Local Group galaxies adhere precisely to the relation defined by more distant galaxies. For…
Phase-Space Correlations Among Systems of Satellite Galaxies
Marcel S. Pawlowski
Driven by increasingly complete observational knowledge of systems of satellite galaxies, mutual spatial alignments and relations in velocities among satellites belonging to a comm…
Gaia EDR3 proper motions of Milky Way dwarfs. II: Velocities, Total Energy and Angular Momentum
François Hammer, Jianling Wang, Marcel Pawlowski +5
Here we show that precise Gaia EDR3 proper motions have provided robust estimates of 3D velocities, angular momentum and total energy for 40 Milky Way dwarfs. The results are stati…
Tracing satellite planes in the Sculptor group: I. Discovery of three faint dwarf galaxies around NGC 253
David Martinez-Delgado, Dmitry Makarov, Behnam Javanmardi +7
In the last years, a new generation of large-scale imaging surveys have probed wide field regions around some nearby galaxies at unprecedented low surface brightness regime (~28.0-…
On the absence of backsplash analogues to NGC 3109 in the CDM framework
Indranil Banik, Moritz Haslbauer, Marcel S. Pawlowski +2
The dwarf galaxy NGC 3109 is receding 105 km/s faster than expected in a CDM timing argument analysis of the Local Group and external galaxy groups within 8 Mpc (Banik \& Zhao 2…
The lopsided distribution of satellites of isolated central galaxies
Peng Wang, Noam I. Libeskind, Marcel S. Pawlowski +4
Satellites are not randomly distributed around their central galaxies but show polar and planar structures. In this paper, we investigate the axis-asymmetry or lopsidedness of sate…
Gaia EDR3 proper motions of Milky Way dwarfs I: 3D Motions and Orbits
Hefan Li, Francois Hammer, Carine Babusiaux +5
Based on Gaia Early Data Release 3 (EDR3), we estimate the proper motions for 46 dwarf spheroidal galaxies (dSphs) of the Milky Way. The uncertainties in proper motions, determined…
