Abstract: We review different aspects of the construction and perturbations of homogeneous black strings in Gauss-Bonnet and third-order Lovelock theory, which are unstable under s-wave perturbations.

Abstract: Among the various modified theories of gravity, scalar-tensor theories are arguablythe most natural extensions to general relativity.
CQG focus issue on hairy BHs
The awakening of the gravitational astronomy era, together with the ever increasing precision of electromagnetic observations, motivates scrutinizing models of alternative compact objects and their phenomenology. As a contribution to this effort, Gr@v researchers will be guest editors of a Focus issue of Classical and Quantum gravity on hairy black holes.
On relativistic geodesy and orbit deviation
Speaker
Dennis Philipp (Bremen U.)

Venue
GAP room

Abstract: The talk is devided into two parts: I will talk about the current status and the prospects of relativistic geodesy and a very interesting project related to this that is called „geoQ“.
Bridging cosmology and astrophysics with gravitational waves
Speaker
Ippocratis Saltas (IA - Lisbon U.)
Event date
Venue
GAP room
Event type
Abstract: In this talk, I will first discuss the challenges one faces when trying to explain the observed late-time acceleration of our Universe, due to the obstacles which the yet unkown physics of dark energy and dark matter place when we try to understand the true theory of gravity at large scales. In this context, I will further explain how model-independent observables have the potential to reveal whether gravity is truly modified at large scales, and will describe a fundamental, underlying relation between large-scale modifications of gravity and the (non-trivial) propagation of gravitational waves, as well as its observational implications for cosmology and astrophysics.
