WebWe analyse the effect of the cosmological expansion on the deflection of light caused by a point mass, adopting the McVittie metric as the geometrical description of a point-like lens embedded in an expanding universe. In the case of a generic, non-constant Hubble parameter, H, we derive and approximately solve the null geodesic equations, finding an … Web9 jan. 2024 · In the same way as for the calibrator sample, we derive peak apparent magnitudes m J and uncertainties σ fit for the Hubble-flow sample from the Gaussian process interpolation, applying Milky Way extinction and K-corrections as above.For the K-corrections, we warp the model SED to match the SN colour (using the mangle option in …
