A symplectic approach to gravitational instability
J. Perez, M. Lachieze-Rey
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…
Experimental limits on the contribution of sub-stellar and stellar objects to the galactic halo
R. Ansari
EROS (Expérience de Recherche d'Objets Sombres) has been monitoring the luminosity of 4 million stars in the Large Magellanic Cloud in order to search for gravitational microlensin…
The determination of by using the TF relation : About particular selection effects
R. Triay, S. Rauzy, M. Lachièze-Rey
This paper completes the statistical modeling of the Hubble flow when a Tully-Fisher type relation is used for estimating the absolute magnitude from a line width…
Wavelet Analysis of Inhomogeneous Data with Application to the Cosmic Velocity Field
S. Rauzy, M. Lachièze-Rey, R. N. Henriksen
In this article we give an account of a method of smoothing spatial inhomogeneous data sets by using wavelet reconstruction on a regular grid in an auxilliary space onto which the…
Pure Luminosity Evolution Hypothesis for QSOs: From Luminosity Functions to Synthetic Catalogues
G. Mathez, L. Van Waerbeke, Y. Mellier +2
This paper describes the simulation of realistic Monte-Carlo extragalactic catalogues, aimed at comparing the behaviour of cosmological tests versus input parameters. QSO catalogue…
EROS VARIABLE STARS : FUNDAMENTAL-MODE AND FIRST OVERTONE CEPHEIDS IN THE BAR OF THE LARGE MAGELLANIC CLOUD
J. P. Beaulieu, P. Grison, W. Tobin +27
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 excel…
