A new analysis of Poincaré dodecahedral space model
S. Caillerie, M. Lachièze-Rey, J. -P. Luminet +3
The full three-year WMAP results (WMAP3) reinforce the absence of large-angle correlations at scales greater than 60 degrees. The Poincare dodecahedral space (PDS) model model, whi…
Constraining Cosmic Topology with CMB Polarization
Alain Riazuelo, Samuel Caillerie, Marc Lachièze-Rey +2
Multiply connected space sections of the universe on a scale smaller than the horizon size can leave an imprint on cosmic microwave background polarization maps, in such a way that…
Laplacian eigenmodes for spherical spaces
M. Lachieze-Rey, S. Caillerie
The possibility that our space is multi - rather than singly - connected has gained a renewed interest after the discovery of the low power for the first multipoles of the CMB by W…
Harmonic projection and multipole Vectors
Marc Lachieze-Rey
We show that the multipole vector decomposition, recently introduced by Copi et al., is a consequence of Sylvester's theorem, and corresponds to the Maxwell's representation. Analy…
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…
