Hubble Constant and Mass Determination of Centaurus A & M83 from TRGB Distances
Adrian Faucher, David Benisty, David F. Mota
An independent determination of the Hubble constant is crucial given the persistent tension between early- and late-Universe measurements. In this study, we analyze the dynamics of…
The Binary Ballet: Mapping Local Expansion Around M81 & M82
Jenny Wagner, David Benisty, Igor D. Karachentsev
This study of the M81 complex and its Hubble flow delivers new and improved Tip of the Red Giant Branch (TRGB)-based distances for nine member galaxies, yielding a total of 58 gala…
Islands in Simulated Cosmos: Probing the Hubble Flow around Groups and Clusters
David Benisty, Antonino Del Popolo
The local Hubble flow provides a valuable probe of the transition between cosmic expansion and nonlinear gravitational dynamics. On large scales, galaxies follow the linear Hubble…
Line-of-Sight Velocity Projection Impact on the Local Group Mass
David Benisty, David Mota
The mass of the Local Group (LG), comprising the Milky Way (MW), Andromeda (M31), and their satellites, is crucial for validating galaxy formation and cosmological models. Traditio…
Unveiling the Coma Cluster Structure: From the Core to the Hubble Flow
David Benisty, Jenny Wagner, Sandeep Haridasu +1
The Coma cluster, embedded in a cosmic filament, is a complex and dynamically active structure in the local Universe. Applying a density-based member selection dbscan to data from…
Multiscale Cosmic Curvature: from Local Structures to Cosmology
David Benisty
This study tackles the impact Dark Energy (DE) in different systems by a simple unifying formalism. We introduce a parameter space that compare gravity across all cosmic scales, us…
