Mass sub-structures in galaxies constrained via lensing

Leon KOOPMANS
Kapteyn Astronomical Institute

Chapitres

  1. Theory of flux- and surface-brightness anomalies due to mass substructure in strong lens galaxies
  2. Observational effects of mass substructures in strong lens galaxies and optimal observational strategies.
  3. Modeling of and inferences about mass substructure in strong lens galaxies.

Résumé

In this series of three lectures on mass-subtructure in strong lens galaxies I will (i) introduce the theory basis of flux and surface-brightness anomalies in lensed image due to mass subtructure, (ii) illustrate the effects of mass substructure in a number of systems that show these anomalies and what observational strategies should be followed to distinguish these from other effects, and (iii) discuss how these anomalies can be modeled (individually or statistically) to derive constraints on the substructure properties, their mass function and potentially their evolution with cosmic time. These three topics will be sequentially covered in 3x1hr lectures.

Bibliographie

The lecture slides will function as notes and will include references to relevant papers and books.
