Using only Ia supernova (SN) observations, it is not possible to distinguish the evolution of the SN absolute magnitude M B from an arbitrary evolution of the Hubble parameter H(z). However, using Etherington's distance-duality relation, which relates the angular and luminosity distances, together with the observed angular baryon acoustic oscillation (BAO) scale at any redshift z, one may calibrate an effective M B (z). This calibration involves a scale which depends on the cosmological model, however the evolution of the effective M B (z) between two redshifts with BAO observations is independent of this scale. The line of sight BAO scale can be used to extend this calibration to redshifts near z. As an application, using BOSS BAO at z = 0.32 and 2.34, JLA supernova at low z and Hubble Space Telescope SN at z > 1.7, we find a statistically insignificant downward shift M B (2.34) − M B (0.32) = −0.08 ± 0.15. Replacing BOSS data with the best fit Planck ΛCDM BAO expectations, we find a shift of −0.24 ± 0.13. With the SN that will be observed by the James Webb Space Telescope, such a calibration at z = 2.34 will be more precise, and it will serve as an anchor for cosmological analyses with the SN that it will observe at yet higher z.

“…Combining supernova data from the supernova cosmology project (SCP) Union 2008 compilation (Kowalski et al 2008) and H(z) data from Stern et al (2010), deviations from the standard DDR have been constrained to few percent (Avgoustidis et al 2010;Ma & Corasaniti 2018). At the same time, direct measurements of CMB temperature at different redshifts, denoted T (z) hereafter, have been obtained at both low redshifts (z 1) via observations of the Sunyaev-Zel'dovich effect in galaxy clusters (Luzzi et al 2009) and at higher redshifts (z > 1) through high-resolution spectroscopy of atomic, ionic, or molecular levels excited by the absorption of CMB photons (Noterdaeme et al 2011).…”

Context. In metric theories of gravity with photon number conservation, the luminosity and angular diameter distances are related via the Etherington relation, also known as the distance duality relation (DDR). A violation of this relation would rule out the standard cosmological paradigm and point to the presence of new physics. Aims. We quantify the ability of Euclid, in combination with contemporary surveys, to improve the current constraints on deviations from the DDR in the redshift range 0 < z < 1.6. Methods. We start with an analysis of the latest available data, improving previously reported constraints by a factor of 2.5. We then present a detailed analysis of simulated Euclid and external data products, using both standard parametric methods (relying on phenomenological descriptions of possible DDR violations) and a machine learning reconstruction using genetic algorithms. Results. We find that for parametric methods Euclid can (in combination with external probes) improve current constraints by approximately a factor of six, while for non-parametric methods Euclid can improve current constraints by a factor of three. Conclusions. Our results highlight the importance of surveys like Euclid in accurately testing the pillars of the current cosmological paradigm and constraining physics beyond the standard cosmological model.

Gravitational lens time-delay as a probe of a possible time variation of the fine-structure constant

A new method based on large scale structure observations is proposed to probe a possible temporal variation of the fine-structure constant ($$\alpha $$ α ). Our analyses are based on time-delay of Strong Gravitational Lensing and Type Ia Supernovae observations. By considering the runaway dilaton scenario, where the cosmological temporal evolution of the fine-structure constant is given by $$\frac{\Delta \alpha }{\alpha } \approx -\gamma \ln {(1+z)}$$ Δ α α ≈ - γ ln ( 1 + z ) , we obtain limits on the physical properties parameter of the model ($$\gamma $$ γ ) at the level $$10^{-2}$$ 10 - 2 ($$1\sigma $$ 1 σ ). Although our limits are less restrictive than those obtained by quasar spectroscopy, the approach presented here provides new bounds on the possibility of $$\frac{\Delta \alpha }{\alpha } \ne 0$$ Δ α α ≠ 0 at a different range of redshifts.
