On the kinematic deconvolution of the local neighbourhood luminosity function
C. Pichon, A. Siebert O. Bienayme
A method for inverting the statistical star counts equation, including proper motions, is presented; in order to break the degeneracy in that equation it uses the supplementary con…
3D Spatial Distribution of the Intergalactic Medium
Patrick Petitjean, Emmanuel Rollinde, Bastien Aracil +2
Very recently a new inversion method has been developped to analyze the intergalactic medium seen in absorption in quasar spectra (the so-called Lyman-alpha forest). This method is…
Physical properties and small-scale structure of the Lyman-alpha forest: Inversion of the HE 1122-1628 UVES spectrum
E. Rollinde, P. Petitjean, C. Pichon
We study the physical properties of the Lyman-alpha forest by applying the inversion method described by Pichon et al. (2001) to the high resolution and high S/N ratio spectrum of…
The XMM-Newton Project
J. G. Bartlett, N. Aghanim, M. Arnaud +16
The abundance of high-redshift galaxy clusters depends sensitively on the matter density $\OmM$ and, to a lesser extent, on the cosmological constant . Measurements of this abun…
Inversion of the Lyman- forest: 3D investigation of the intergalactic medium
C. Pichon, J. L. Vergely, E. Rollinde +2
We discuss the implementation of Bayesian inversion methods in order to recover the properties of the intergalactic medium from observations of the neutral hydrogen Lyman- absor…
