Dark energy and the Hubble constant with standard candles and standard clocks

In this talk, I will summarise our recent results on constraining dark energy and measuring the local expansion rate, i.e. the Hubble constant, with Type Ia supernovae and gravitationally lensed transients. Despite growing evidence of accelerated expansion of the universe, the physical mechanism driving this phenomenon is poorly understood. Using geometric probes, we find no significant evidence suggesting a paradigm outside standard cosmology, i.e. dark energy as a cosmological constant, however, we obtain moderate evidence disfavouring some of the non-standard models.
