Safely simplifying redshift drift computations in inhomogeneous cosmologies: Insights from LTB Swiss-cheese models
David Rønne Sallingboe, Sofie Marie Koksbang
One of the most important discoveries in cosmology is the accelerated expansion of the Universe. Yet, the accelerated expansion has only ever been measured {\em in}directly. Redshi…
Transverse Velocities in Real-Time Cosmology: Position Drift in Relativistic N-Body Simulations
Alexander Oestreicher, Chris Clarkson, Julian Adamek +1
The era of real-time cosmology has begun. It is now possible to directly measure the apparent drift of high-redshift astronomical sources across the sky . Th…
Redshift Drift in Relativistic N-Body Simulations
Alexander Oestreicher, Chris Clarkson, Julian Adamek +1
The cosmological redshift drift promises to be the first observable directly measuring the evolution of the cosmic expansion rate and should be detectable with upcoming surveys by…
