Melchior, A L., Afonso, C., Ansari, R., Aubourg, E., Baillon, P., Bareyre, P., ...
We apply the pixel method of analysis (sometimes called ``pixel lensing'') to a small subset of the EROS-1\ microlensing observations of the bar of the Large Magellanic Cloud (LMC). The pixel method...
Examples of Berezin-Toeplitz Quantization: Finite sets and Unit Interval (2006)
Gazeau, J. P., Garidi, T., Huguet, E., Lachieze-Rey, M., Renaud, J.
We present a quantization scheme of an arbitrary measure space based on overcomplete families of states and generalizing the Klauder and the Berezin-Toeplitz approaches. This scheme could reveal...
About the Malmquist bias in the determination of H0 and of distances of galaxies (2005)
Triay, R., Lachieze-Rey, M., Rauzy, S.

Laplacian eigenmodes for spherical spaces (2005)
Lachieze-Rey, M., Caillerie, S.
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 WMAP. To test the...
A new basis for eigenmodes on the Sphere (2003)
The usual spherical harmonics $Y_{\ell m}$ form a basis of the vector space ${\cal V} ^{\ell}$ (of dimension $2\ell+1$) of the eigenfunctions of the Laplacian on the sphere, with eigenvalue...

Theoretical Necessity of an External Scalar Field in the Kaluza-Klein Theory (I) (2000)
Mbelek, J. P., Lachieze-Rey, M.
We show that the principle of least action is generally inconsistent with the usual Kaluza-Klein program, the higher dimensional Einstein-Hilbert action being unbounded from below. This inconsistency...
The Friedmann-Lemaitre models in perspective (2000)
I show that all FRW models (four dimensional pseudo-Riemannian manifolds with maximally symmetric space) can be embedded in a flat Minkowski manifold with 5 dimensions. The pseudo Riemannian metric...
Yasu, Y., Yasu, Y., Yasu, Y., Yasu, Y., Yasu, Y., Ferlet, R., ...
We present CCD phase-binned light curves at 490\,nm for 97 Cepheid variable stars in the bar of the LMC. The photometry was obtained as part of the French EROS project and has excellent phase...

Lachieze-Rey, M., Luminet, J. P.
General relativity does not allow one to specify the topology of space, leaving the possibility that space is multi-- rather than simply--connected. We review the main mathematical properties of...
Lehoucq, R., Lachieze-Rey, M., Luminet, J. P.
We assume that the Universe has a non trivial topology whose compact spatial sections have a volume significantly smaller than the horizon volume. By a topological lens effect, such a "folded" space...

A symplectic approach to gravitational instability (1995)
We present a global approach of non-dissipative physics. Based on symplectic mechanics this technique allows us to obtain the solution of a very large class of problems in terms of a Taylor expand....
V/Vmax statistic and Neo-Classic Cosmological Tests (1995)
Van Waerbeke, L., Mathez, G., Mellier, Y., Bonnet, H., Lachieze-Rey, M.
A new cosmological test is derived, based on the distribution of individual V/Vmax in a complete redshift-limited sample of distant objects. The fundamental assumption is that, in any bin of absolute...
Mathez, G., Van Waerbeke, L., Mellier, Y., Bonnet, H., Lachieze-Rey, M.
This paper describes the simulation of realistic Monte-Carlo extragalactic catalogues, aimed at comparing the behaviour of cosmological tests versus input parameters. QSO catalogues are built on a...
