Dust environment and dynamical history of a sample of short period comets
F. J. Pozuelos, F. Moreno, F. Aceituno +53
Aims. In this work, we present an extended study of the dust environment of a sample of short period comets and their dynamical history. With this aim, we characterized the dust ta…
Cosmological tests of modified gravity: constraints on theories from the galaxy clustering ratio
Julien Bel, Philippe Brax, Christian Marinoni +1
The clustering ratio , a large-scale structure observable originally designed to constrain the shape of the power spectrum of matter density fluctuations, is shown to provide a…
Probing non-standard gravity with the growth index: a background independent analysis
Heinrich Steigerwald, Julien Bel, Christian Marinoni
Measurements of the growth index provide a clue as to whether Einstein's field equations encompass gravity also on large cosmic scales, those where the expansion of the univ…
Measuring the growth of matter fluctuations with third-order galaxy correlations
Kai Hoffmann, Julien Bel, Enrique Gaztanaga +3
Measurements of the linear growth factor at different redshifts are key to distinguish among cosmological models. One can estimate the derivative from red…
The VIMOS Public Extragalactic Redshift Survey (VIPERS). Never mind the gaps: comparing techniques to restore homogeneous sky coverage
O. Cucciati, B. R. Granett, E. Branchini +28
[Abridged] Non-uniform sampling and gaps in sky coverage are common in galaxy redshift surveys, but these effects can degrade galaxy counts-in-cells and density estimates. We carry…
