Watching the universe expand in real time

Beatriz G. Pereira

The redshift drift of objects following the Hubble flow provides us with a unique (but still unfulfilled) opportunity to watch the universe expand in real time, and in a model-independent way. The first practical proposal for this measurement emerged in the context of the ELT (the so-called Sandage-Loeb test), but in recent years redshift drift measurements with other facilities have also been proposed. In this contribution we provide a comparative analysis of the constraining power of these measurements for various cosmological scenarios. Our analysis includes the latest techniques and facilities proposed in the Astro 2020 white papers call.
