Spatially resolved studies of lensed galaxies

Chapitres

  1. Introduction on magnification of strongly-lensed galaxies and source reconstruction techniques
  2. Resolved morphology of lensed galaxies
  3. Resolved kinematics of lensed galaxies
  4. Metallicity gradients

Résumé

In these 2 lectures, I will present the topic of using strong lensing to derive spatially-resolved properties in the sources. After introducing the method of source reconstruction, I will detail 3 main observational applications using current instrumentation (high resolution imaging, long-slit or IFU spectroscopy), and discuss the specific effects inherent to each analysis.
