Exploring cosmic homogeneity with the BOSS DR12 galaxy sample
Pierros Ntelis, Jean-Christophe Hamilton, Jean-Marc Le Goff +16
In this study, we probe the transition to cosmic homogeneity in the Large Scale Structure (LSS) of the Universe using the CMASS galaxy sample of BOSS spectroscopic survey which cov…
A 14 Gpc study of cosmic homogeneity using BOSS DR12 quasar sample
Pierre Laurent, Jean-Marc Le Goff, Etienne Burtin +16
The BOSS quasar sample is used to study cosmic homogeneity with a 3D survey in the redshift range . We measure the count-in-sphere, , i.e. the average number o…
Simulations of BAO reconstruction with a quasar Lyman-alpha survey
J. -M. Le Goff, C. Magneville, E. Rollinde +13
The imprint of Baryonic Acoustic Oscillations (BAO) on the matter power spectrum can be constrained using the neutral hydrogen density in the intergalactic medium as a tracer of th…
EROS Variable Stars : Discovery of Beat Cepheids in the Small Magellanic Cloud and the effect of metallicity on pulsation
J. P. Beaulieu, M. Krockenberger, D. D. Sasselov +27
We report the discovery of eleven beat Cepheids in the Small Magellanic Cloud, using data obtained by the EROS microlensing survey. Four stars are beating in the fundamental and fi…
Metallicity Effects on the Cepheid Extragalactic Distance Scale from EROS photometry in LMC and SMC
D. D. Sasselov, J. P. Beaulieu, C. Renault +30
This is an investigation of the period-luminosity relation of classical Cepheids in samples of different metallicity. It is based on 481 Cepheids in the Large and Small Magellanic…
The effect of metallicity on the Cepheid distance scale and its implications for the Hubble constant () determination
J. P. Beaulieu, D. D. Sasselov, C. Renault +30
Recent HST determinations of the expansion's rate of the Universe (the Hubble constant, H_0) assumed that the Cepheid Period-Luminosity relation at V and I are independent of metal…
