The variance of the locally measured Hubble parameter explained with different estimators
Io Odderskov, Steen Hannestad, Jacob Brandbyge
We study the expected variance of measurements of the Hubble constant, , as calculated in either linear perturbation theory or using non-linear velocity power spectra derived…
Measuring the velocity field from type Ia supernovae in an LSST-like sky survey
Io Odderskov, Steen Hannestad
With the upcoming sky survey with the Large Synoptic Survey Telescope a great sample of type Ia supernovae will be observed, allowing for a precise mapping of the velocity structur…
The Local Value of in an Inhomogeneous Universe
I. Odderskov, S. M. Koksbang, S. Hannestad
The effects of local inhomogeneities on low redshift determinations are studied by estimating the redshift-distance relation of mock sources in N-body simulations. The result…
The effect of interacting dark energy on local measurements of the Hubble constant
Io Odderskov, Marco Baldi, Luca Amendola
In the current state of cosmology, where cosmological parameters are being measured to percent accuracy, it is essential to understand all sources of error to high precision. In th…
On the local variation of the Hubble constant
Io Odderskov, Steen Hannestad, Troels Haugbølle
We have carefully studied how local measurements of the Hubble constant, , can be influenced by a variety of different parameters related to survey geometry, depth, and size,…
