Galaxie pipeline
The "Galaxie" pipeline is designed to provide quick and automatic
data treatment for studying galaxies's spectral energy distributions.
"Galaxie" is written in Java, which ensures compatibility, high
performance, and easy extension mechanism.
About
TOP
The "Galaxie" pipeline is designed for high performance treatment of
galaxies's observations, from the raw data to the high level data
products. It can for example:
- extract 1D spectra from 2D/3D observations
- measure spectral features (emission lines, absorption lines,
indices) from a set of 1D spectra (see also "platefit_vimos"
sub-project)
- calculate physical parameters from emission lines (such as
gas-phase metallicities, star formation rates, ...)
- classify emission-line galaxies into star-forming galaxies and
active galactic nuclei (see also "JClassif" sub-project)
- compute stellar population models with various histories (star
formation, metal enrichment, dust, ...) and any input stellar spectra
library
- calculate physical parameters from both spectra and broad-band
magnitudes with a Bayesian approach (such as stellar masses, star
formation rates, ages, stellar metallicities, ...)
- calculate velocity and dispersion maps from 2D/3D observations
- modelize the dynamics from velocity and dispersion maps
- plot and fit all results
Up to know, the whole "Galaxie" pipeline is still under development to
make it an interactive and easy-to-use tool, but it will be soon
progressively released on this website !
