1- Cosmological simulations of galaxy formation and reionisation

Joakim Rosdahl & Thibault Garel

Abstract: In this tutorial you’ll run 2d radiation hydrodynamics (RHD) experiments with RAMSES-RT. The Fortran-written code is designed for running 3d simulations, but to maintain a good workflow and be able to run a few experiments in a reasonable time, it is best that we restrict ourselves here to 2d runs. If you’re happy with the experience and are eager to go to the next dimension, it is a fairly straightforward thing to do and an introductory 3d setup is presented.

2-LENSTOOL

David Lagattuta

Abstract: LENSTOOL (Jullo et al. 2007) is a widely-used, Bayesian-based software package designed to (parametrically) reconstruct the mass distribution of gravitational lenses, using the multiply-imaged background galaxies as constraints. In this tutorial I will give an overview of the theory behind LENSTOOL and demonstrate its many capabilities on real data. I will also compare the differences between parametric modeling codes like LENSOOL and their non-parametric ("free-form") counterparts, highlighting the pluses and minuses of each technique.

4- Automated Radio Telescope Imaging Pipeline - ARTIP

Neeraj Gupta

Abstract: ARTIP is an end-to-end pipeline automating the entire process of flagging, calibrationand imaging for radio-interferometric data. The pipeline uses various statistical techniques toautomatically identify bad antennas, baselines, time ranges and radio frequency interference (RFI). The pipeline is written using standard python libraries and the CASA package, and is beingdeveloped to deal with large datasets from upcoming spectral line surveys. In the tutorial, I will provide an overview of the pipeline, and we will try it on a GMRT dataset.
