Escape Velocity Mass of Abell S1063
Alexander Rodriguez, Christopher J. Miller, Vitali Halenka +1
We measure the radius-velocity phase-space edge profile for Abell S1063 using galaxy redshifts from arXiv:1409.3507 and arXiv:2109.03305. Combined with a cosmological model and aft…
Testing the theory of gravity with DESI: estimators, predictions and simulation requirements
Shadab Alam, Christian Arnold, Alejandro Aviles +33
Shortly after its discovery, General Relativity (GR) was applied to predict the behavior of our Universe on the largest scales, and later became the foundation of modern cosmology.…
Quantifying the Projected Suppression of Cluster Escape Velocity Profiles
Vitali Halenka, Christopher J. Miller, Paige Vansickle
The 3D radial escape-velocity profile of galaxy clusters has been suggested to be a promising and competitive tool for constraining mass profiles and cosmological parameters in an…
Testing emergent gravity with mass densities of galaxy clusters
Vitali Halenka, Christopher J. Miller
We use a sample of 23 galaxy clusters to test the predictions of emergent gravity (EG) as alternative to dark matter. Our sample has both weak-lensing inferred total mass profiles…
Deriving galaxy cluster velocity anisotropy profiles from a joint analysis of dynamical and weak lensing data
Alejo Stark, Christopher J. Miller, Vitali Halenka
We present an analytic approach to lift the mass-anisotropy degeneracy in clusters of galaxies by utilizing the line-of-sight velocity dispersion of clustered galaxies jointly with…
Power-law cosmology, SN Ia, and BAO
A. Dolgov, V. Halenka, I. Tkachev
We revise observational constraints on the class of models of modified gravity which at low redshifts lead to a power-law cosmology. To this end we use available public data on Sup…
Studies of Cosmic Ray Composition and Air Shower Structure with the Pierre Auger Observatory
The Pierre Auger Collaboration, J. Abraham, P. Abreu +470
Studies of the composition of the highest energy cosmic rays with the Pierre Auger Observatory, including examination of hadronic physics effects on the structure of extensive air…
