Strings with Non-Relativistic Conformal Symmetry and Limits of the AdS/CFT Correspondence
Troels Harmark, Jelle Hartong, Lorenzo Menculini +2
We find a Polyakov-type action for strings moving in a torsional Newton-Cartan geometry. This is obtained by starting with the relativistic Polyakov action and fixing the momentum…
Action Principle for Newtonian Gravity
Dennis Hansen, Jelle Hartong, Niels A. Obers
We derive an action whose equations of motion contain the Poisson equation of Newtonian gravity. The construction requires a new notion of Newton--Cartan geometry based on an under…
Observational signature of near-extremal Kerr-like black holes in a modified gravity theory at the Event Horizon Telescope
Minyong Guo, Niels A. Obers, Haopeng Yan
We study the shadows cast by near-extremal Kerr-MOG black holes for different values of the parameter in modified gravity (MOG). In particular, we consider an isotropic emitter orb…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
