Debiasing Local Cluster Infall Reveals : Application to the Virgo Cluster
Bastien Carreres, David Benisty, Jenny Wagner +3
Galaxy recession velocities are commonly used to measure the Hubble constant, , with peculiar velocities treated as random noise. Around massive clusters, however, these motio…
Tighter Dark Matter Constraints from the Projected Mass Method: A Neural Network Enhanced Method for Galaxy Groups and Clusters
Yinbo Huang, David Benisty
Measuring the total mass of the Milky Way and nearby galaxy groups is difficult because classical dynamical estimators rely on assumptions about satellite orbital geometry that are…
Tango of Titans: Centaurus A and M83 as a Local Group Analog
David Benisty, Noam Libeskind, Dmitry Makarov
Centaurus A (CenA) and M83 form one of the most massive galaxy pairs in the nearby Universe. Although their observed heliocentric velocities suggest motion that is not obviously in…
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…
