Understand
The luminosity-redshift relation of cosmological standard candles provides information about the relative energy composition of our Universe.
- In particular, the observation of type Ia supernovae up to redshift of z~2 indicate a universe which is dominated today by dark matter and dark energy.
- The propagation distance of light from these sources is of the order of the Hubble radius and serves as a very sensitive probe of feeble inelastic photon interactions with background matter, radiation or magnetic fields.
- In this paper we discuss the limits on mini-charged particle models arising from a dimming effect in supernova surveys.
