The Redshift Difference in Gravitational Lensed Systems: A Novel Probe of Cosmology
Chengyi Wang, Krzysztof Bolejko, Geraint F. Lewis
The exploration of the redshift drift, a direct measurement of cosmological expansion, is expected to take several decades of observation with stable, sensitive instruments. We int…
The Instantaneous Redshift Difference of Gravitationally Lensed Images: Theory and Observational Prospects
Chengyi Wang, Krzysztof Bolejko, Geraint F. Lewis
Due to the expansion of our Universe, the redshift of distant objects changes with time. Although the amplitude of this redshift drift is small, it will be measurable with a decade…
Direct detection of the cosmic expansion: the redshift drift and the flux drift
Krzysztof Bolejko, Chengyi Wang, Geraint F. Lewis
The redshift drift, the change of cosmological redshift with time, is a direct consequence of the expansion of the Universe. Thus the measurement of the cosmological redshift drift…
