Bounding the Cosmological Constant using Galactic Rotation Curves from the SPARC Dataset
David Benisty, David Vasak, Jürgen Struckmeier +1
Dark energy (and its simplest model, the Cosmological Constant or ) acts as a repulsive force that opposes gravitational attraction. Assuming galaxies maintain a steady state ov…
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…
Late-Time constraints on Interacting Dark Energy: Analysis independent of , and
David Benisty, Supriya Pan, Denitsa Staicova +2
We investigated a possible interaction between cold dark matter and dark energy, corresponding to a well-known interacting dark energy model discussed in the literature within the…
Weighing Milky Way and Andromeda in an expanding CDM Universe: Decreasing the Local Group mass
David Benisty
The dynamics of the Local Group (LG), especially the contribution of the Milky Way (MW) and Andromeda (M31) galaxies, is sensitive to the presence of dark energy. This work analyze…
