The Cosmological Dipole in Tilted Anisotropic Universes
Alicia Martín, Constantinos Skordis, Deaglan J. Bartlett +3
There is tentative evidence for a mismatch between the rest frames of matter and the cosmic microwave background, the "quasar dipole anomaly". We consider such a dipole in tilted a…
Towards galaxy cluster models in Aether-Scalar-Tensor theory: isothermal spheres and curiosities
Amel Durakovic, Constantinos Skordis
The Aether-Scalar-Tensor (AeST) theory is an extension of General Relativity (GR) which can support Modified Newtonian Dynamics (MOND) behaviour in its static weak-field limit, and…
Aether Scalar Tensor (AeST) theory: Quasistatic spherical solutions and their phenomenology
Peter Verwayen, Constantinos Skordis, Céline Bœhm
There have been many efforts in the last three decades to embed the empirical MOND program into a robust theoretical framework. While many such theories can explain the profile of…
Cosmic backgrounds from the radio to the far-infrared: recent results and perspectives from cosmological and astrophysical surveys
Carlo Burigana, Elia Sefano Battistelli, Laura Bonavera +8
Cosmological and astrophysical surveys in various wavebands, in particular from the radio to the far-infrared, offer a unique view of the universe's properties and the formation an…
A new relativistic theory for Modified Newtonian Dynamics
Constantinos Skordis, Tom Zlosnik
We propose a relativistic gravitational theory leading to modified Newtonian dynamics, a paradigm that explains the observed universal galactic acceleration scale and related pheno…
Dark Matter properties through cosmic history
Stéphane Ilić, Michael Kopp, Constantinos Skordis +1
We perform the first test of dark matter (DM) stress-energy evolution through cosmic history, using cosmic microwave background measurements supplemented with baryon acoustic oscil…
