The physics of condensed matter in the cosmos

 

 Thesis Supervisor: Ralf Siebenmorgen


Abstract

Photons are scattered, polarised, absorbed, or re-emitted by dust particles during their travel through the cosmos from origin to our detectors. Dust confuses our available information of the composition and structure of various object types such as star forming regions, proto-planetary or debris disks, the end-phases and death of the stars or supernovae, and more so, of extra-galactic objects, starburst galaxies, active galactic nuclei, gamma ray bursts and more general the inter-stellar or extra-galactic medium. Recent advances in computer technology enables the use of efficient Monte Carlo (MC) techniques to study the transport of radiation in arbitrary three-dimensional geometry for polarised or unpolarised light through a dusty medium.

The goal of this PhD project is to study and explore the physics of the dust or applying such MC treatments that shall confronted to existing archival or new observations.  This is a timely project to support understanding of new data obtained with our modern instrumentation that are available at the VLT, ALMA, and other facilities or to simulate new science case for future instrumentation projects such as METIS of ESO's Extremely Large Telescope (ELT).
