Strong lensing in the Einstein-Straus solution
Thomas Schucker
We analyse strong lensing in the Einstein-Straus solution with positive cosmological constant. For concreteness we compare the theory to the light deflection of the lensed quasar S…
Strong lensing with positive cosmological constant
Thomas Schucker
Strong lensing by an isolated spherically symmetric mass distribution is considered in presence of a positive cosmological constant. Deflection angles and time delay are computed a…
Cosmological constant and time delay
Thomas Schucker, Noureddine Zaimen
The effect of the cosmological constant on the time delay caused by an isolated spherical mass is calculated without using the lens equation and compared to a recent observational…
Cosmological constant and lensing
Thomas Schucker
The effect of the cosmological constant on the curvature of light due to an isolated spherical mass is recalculated without using the lens equation and compared to a lensing cluste…
Testing for monotonicity in the Hubble diagram
Nicolai Meinshausen, John Rice, Thomas Schücker
General relativistic kinematics and the cosmological principle alone imply a monotonicity constraint in the Hubble diagram, which we confront to present-day supernova data. We use…
Perturbations to the Hubble diagram
Thomas Schucker, Ilhem ZouZou
We compute the linear responses of the Hubble diagram to small scalar perturbations in the Robertson-Walker metric and to small peculiar velocities of emitter and receiver. We disc…
