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…
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…
Galaxy infall models for arbitrary velocity directions
Jenny Wagner, David Benisty
For most galaxies in the cosmos, our knowledge of their motion is limited to line-of-sight velocities from redshift observations. To determine the radial velocity between two galax…
Galaxy groups in the presence of Cosmological Constant: Increasing the Masses of Groups
David Benisty, Moshe M. Chaichian, Anca Tureanu
The boundaries of galaxy groups and clusters are defined by the interplay between the Newtonian attractive force and the decoupling from the local expansion of the Universe. This w…
Tracking the Local Group Dynamics by Extended Gravity
David Benisty, Salvatore Capozziello
The Local Group (LG) of galaxies, modeled as a two body problem, is sensitive to cosmological contributions like those related to the presence of a cosmological constant into d…
