Perturbations of Cosmological Redshift Drift
Pedro Bessa, Ruth Durrer, Dennis Stock
In this paper we calculate the linear perturbations of the cosmological redshift drift. We show explicitly that our expressions are gauge-invariant and compute the power spectrum o…
The Hawking Energy in a Perturbed Friedmann-Lemaître Universe
Dennis Stock, Enea Di Dio, Ruth Durrer
Hawking's quasi-local energy definition quantifies the energy enclosed by a spacelike 2-sphere in terms of the amount of lightbending on the sphere caused by the energy distributio…
Redshift weighted galaxy number counts
William L Matthewson, Dennis Stock, Ruth Durrer
In this paper we introduce the `redshift fluctuation' as a gauge-invariant cosmological observable and give its fully relativistic expression at first order in cosmological perturb…
Applications of the Hawking Energy in Inhomogeneous Cosmology
Dennis Stock
The past lightcone of an observer in a cosmological spacetime is the unique geometric structure directly linked to observations. After general properties of the Hawking energy alon…
The Hawking Energy on the Past Lightcone in Cosmology
Dennis Stock
This work studies the Hawking energy in a cosmological context. The past lightcone of a point in spacetime is the natural geometric structure closely linked to cosmological observa…
Quantum Improved Schwarzschild-(A)dS and Kerr-(A)dS Space-times
Jan M. Pawlowski, Dennis Stock
We discuss quantum black holes in asymptotically safe quantum gravity with a scale identification based on the Kretschmann scalar. After comparing this scenario with other scale id…
The projected gravitational potential of the galaxy cluster MACS~J1206 derived from galaxy kinematics
Dennis Stock, Sven Meyer, Eleonora Sarli +7
We reconstruct the radial profile of the projected gravitational potential of the galaxy cluster MACS-J1206 from 592 spectroscopic measurements of velocities of cluster members. Fo…
