Gravitational edge mode powers galaxy flat rotation curves
Obinna Umeh
The point-particle approximation is foundational to modelling clustering of matter in the universe, but is fundamentally inconsistent within General Relativity due to associated sp…

Cosmological evolution of the gravitational entropy of the large-scale structure
Giovanni Marozzi, Jean-Philippe Uzan, Obinna Umeh +1
We consider the entropy associated with the large-scale structure of the Universe in the linear regime, where the Universe can be described by a perturbed Friedmann-Lemaître spacet…

Non-linear relativistic contributions to the cosmological weak-lensing convergence
Sambatra Andrianomena, Chris Clarkson, Prina Patel +2
Relativistic contributions to the dynamics of structure formation come in a variety of forms, and can potentially give corrections to the standard picture on typical scales of 100…
