The MUSE-Faint survey V. The binary fraction of Leo T
Daniel Vaz, Jarle Brinchmann, Sebastian Kamann +3
The Leo T dwarf galaxy, the faintest and least massive galaxy known to have recent star formation (), exhibits a high dynamical mass-to-light ratio based on its stellar…
The radial acceleration relation at the EDGE of galaxy formation: testing its universality in low-mass dwarf galaxies
Mariana P. Júlio, Justin I. Read, Marcel S. Pawlowski +6
A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide range of mass () - the Radi…
GravSphere2: A higher-order Jeans method for mass-modeling spherical stellar systems
Andrés Bañares-Hernández, Justin I. Read, Mariana P. Júlio
Mass-modeling methods are used to infer the gravitational field of stellar systems, from globular clusters to giant elliptical galaxies. While many methods exist, most require assu…
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…
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…
Gas thermodynamics meets galaxy kinematics: Joint mass measurements for eROSITA galaxy clusters
Pengfei Li, Ang Liu, Matthias Kluge +13
The mass of galaxy clusters is a critical quantity for probing cluster cosmology and testing theories of gravity, but its measurement could be biased given assumptions are inevitab…
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…
Satellite group infall into the Milky Way: exploring the Crater-Leo case with new HST proper motions
Mariana P. Júlio, Marcel S. Pawlowski, Sangmo Tony Sohn +3
Context. Within Cold Dark Matter (CDM) simulations, Milky Way-like galaxies accrete some of their satellite galaxies in groups of 3-5 members rather than individually. It wa…
The MUSE-Faint survey. III. Constraining scalar field dark matter with Antlia B
Mariana P. Júlio, Jarle Brinchmann, Sebastiaan L. Zoutendijk +7
Aims. We use the stellar line-of-sight velocities of Antlia B (Ant B), a faint dwarf galaxy in the NGC 3109 association, to derive constraints on the fundamental properties of scal…
Measuring galaxy cluster mass profiles into the low acceleration regime with galaxy kinematics
Pengfei Li, Yong Tian, Mariana P. Júlio +7
We probe the dynamical mass profiles of 10 galaxy clusters from the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS) using galaxy kinematics. We numerically solve the spherical…
