On Gravitational Waves in Spacetimes with a Nonvanishing Cosmological Constant
J. Näf, P. Jetzer, M. Sereno
We study the effect of a cosmological constant on the propagation and detection of gravitational waves. To this purpose we investigate the linearised Einstein's equations with…
The role of Lambda in the cosmological lens equation
M. Sereno
The cosmological constant Lambda affects cosmological gravitational lensing. Effects due to Lambda can be studied in the framework of the Schwarzschild-de Sitter spacetime. Two nov…
The dynamical state of RX J1347.5-1145 from a combined strong lensing and X-ray analysis
M. Miranda, M. Sereno, E. De Filippis +1
We perform a combined X-ray and strong lensing analysis of RX J1347.5-1145, one of the most luminous galaxy clusters at X-ray wavelengths. We show that evidence from strong lensing…
On the influence of the cosmological constant on gravitational lensing in small systems
M. Sereno
The cosmological constant Lambda affects gravitational lensing phenomena. The contribution of Lambda to the observable angular positions of multiple images and to their amplificati…
Primary caustics and critical points behind a Kerr black hole
M. Sereno, F. De Luca
The primary optical caustic surface behind a Kerr black hole is a four-cusped tube displaced from the line of sight. We derive the caustic surface in the nearly asymptotic region f…
