Testing gravity on large scales. The skewness of the galaxy distribution at z~1
C. Marinoni, L. Guzzo, A. Cappi +54
We study the evolution of the low-order moments of the galaxy overdensity distribution over the redshift interval 0.7<z<1.5. We find that the variance and the normalized skewness e…
Strong lensing in the Einstein-Straus solution
Thomas Schucker
We analyse strong lensing in the Einstein-Straus solution with positive cosmological constant. For concreteness we compare the theory to the light deflection of the lensed quasar S…
Strong lensing with positive cosmological constant
Thomas Schucker
Strong lensing by an isolated spherically symmetric mass distribution is considered in presence of a positive cosmological constant. Deflection angles and time delay are computed a…
A test of the nature of cosmic acceleration using galaxy redshift distortions
L. Guzzo, M. Pierleoni, B. Meneux +48
Observations of distant supernovae indicate that the Universe is now in a phase of accelerated expansion the physical cause of which is a mystery. Formally, this requires the inclu…
On the determination of curvature and dynamical Dark Energy
J. -M. Virey, D. Talon-Esmieu, A. Ealet +2
Constraining simultaneously the Dark Energy(DE) equation of state and the curvature of the Universe is difficult due to strong degeneracies. To circumvent this problem when analyzi…
Testing for monotonicity in the Hubble diagram
Nicolai Meinshausen, John Rice, Thomas Schücker
General relativistic kinematics and the cosmological principle alone imply a monotonicity constraint in the Hubble diagram, which we confront to present-day supernova data. We use…
