A new chemodynamical tool to study the evolution of galaxies in the local Universe: a quick and accurate numerical technique to compute gas cooling rate for any chemical composition [PDF]

open access: yes, 2007
We have developed a quick and accurate numerical tool to compute gas cooling whichever its chemical composition.Comment: 3 pages, 2 figures, to appear in the Proceedings of "Heating vs.

Tales within Tales and Cutoffs within Cutoffs: What Sets the Mass Scale for Galaxies? [PDF]

open access: yes, 2001
Please answer ``yes'' or ``no'': 1. Does the mass function for clusters of galaxies cut off exponentially? 2. Does the luminosity function for galaxies cut off exponentially? 3. Is the dependence of virial velocity on galaxy luminosity a power law?

Photometric and kinematical study of nearby groups of galaxies around IC 65 and NGC 6962 [PDF]

open access: yes, 2006
We discuss the structure, galaxy content and kinematics of a sparse, probably collapsing group around IC 65 and an evolved rich group around NGC 6962Comment: Poster contribution on 2 pages with 2 figures to be published in ESO Astrophysics Symposia ...

Astrophysics on the GRAPE Family of Special Purpose Computers [PDF]

open access: yes, 1998
The GRAPE-4, the world's fastest computer in 1995-1997, has produced some major scientific results, through a wide diversity of large-scale simulations in astrophysics.

Observed Properties of Dark Matter on Small Spatial Scales [PDF]

open access: yes, 2007
The nature of dark matter is one of the outstanding questions of astrophysics. The internal motions of member stars reveal that the lowest luminosity galaxies in the Local Group are the most dark-matter dominated.

Spiral galaxies with large optical warps [PDF]

open access: yes, 1999
As a result of our statistical study of 540 edge-on galaxies, we present here the images and preliminary statistical analysis of a sub-sample of 60 galaxies, that were selected to be S-type warped spirals.

Tracing the Mass-Assembly History of Galaxies with Deep Surveys

open access: yes, 2007
We use the optical and near-infrared galaxy samples from the Munich Near-Infrared Cluster Survey (MUNICS), the FORS Deep Field (FDF) and GOODS-S to probe the stellar mass assembly history of field galaxies out to z ~ 5.

N-body simulations of galaxies and groups of galaxies with the Marseille GRAPE systems [PDF]

open access: yes, 1998
I review the Marseille GRAPE systems and the N-body simulations done with them. I first describe briefly the available hardware and software, their possibilities and their limitations.

Compact jets as probes for sub-parsec scale regions in AGN

open access: yes, 2007
Compact relativistic jets in active galactic nuclei offer an effective tool for investigating the physics of nuclear regions in galaxies. The emission properties, dynamics, and evolution of jets in AGN are closely connected to the characteristics of the ...

Stability of disk-like galaxies--Part I: Stability via reduction [PDF]

open access: yes, 2006
We prove the existence and stability of flat steady states of the Vlasov-Poisson system, which in astrophysics are used as models of disk-like galaxies.
