Research Projects
Modelling icy envelopes
Pooneh Nazari (ESO)
After the launch of JWST multiple studies have analysed the ice abundances in protostellar systems. However, it is not clear whether and how the measured ice column density ratios change for objects with different physical structures. In this project, the student will use radiative transfer models to measure ice abundances of carbon monoxide, carbon dioxide, and water in protostellar systems with a variety of physical conditions and assess whether changes in physical conditions across systems will alter the column density ratios. This will be done by running radiative transfer models of RADMC3D and analysing their outputs using Python. The exact scope of the project will be developed in consultation with the student, to take their interest into account.
Hunt for new molecules
Pooneh Nazari (ESO)
Hundreds of molecules have been detected in the interstellar medium in the past decades. However, this number is still growing as new data become available. In this project, the student will use archival ALMA data of one or more objects to search for new molecules. A particular attention will be given to 3-carbon species. The project involves downloading the spectra from ALMA archive and first modelling as many lines as possible with CASSIS spectral analysis tool before focusing on the weaker lines of potentially exotic species. The exact scope of the project will be developed in consultation with the student, to take their interest into account.
Galaxy evolution
Danial Langeroodi (DARK, University of Copenhagen), Pooneh Nazari (ESO)
A project is available on the topic of galaxy evolution. The project will broadly cover use of ALMA and JWST archival data to better understand the chemical enrichment and evolution of galaxies. The exact scope and topic of the project will be developed in consultation with the student, to take their interest into account.
