Bachelor and Master Thesis
Below we list ideas for Bachelor and Master thesis. Please also view the Doctoral Thesis topics we offer, most of which can also be scaled to Master thesis topics. We will be happy to explain in more detail and define a project that suits your interests and technical background. You could also work on any of these projects within an internship, to get to know us and the subject.
Galaxy Clusters and Cosmology
- Missing baryons in the cosmic filaments: in this project we will use a galaxy-pair catalog and Planck all-sky data to look for the signatures of missing baryons in the cosmic filaments, via thermal and kinematic SZ effects. We can also go beyond the thermal imaging and look for nonthermal emissions, this time using radio maps and the same galaxy-pair catalog.
- Nonthermal SZ within AGN bubbles: existence of nonthermal, high-energy electrons inside AGN bubbles is known from hard X-ray observations, but no constraints exist for the total energy budget for these electrons. We shall look for the signature of nonthermal SZ in these AGN bubbles
- Galaxy cluster velocities from kSZ: we will use the available Planck data for some well-known clusters and see what can be inferred on their cosmic velocities, under various assumptions on mass, temperature, dust content, etc
- Density inhomegeneity in galaxy clusters: we will use available SZ maps of two very well-known clusters (Coma and A2163) and combined the results with hard X-ray data from the NuSTAR satellite, to make a measurement of gas clumping using a completely new method!
- Mapping of a giant radio halo: we can choose one of the known clusters from our (tons of!) VLA data and use the existing VLA pipeline to try to make a radio halo map.
- ALMA SZ image of a cluster: we will combine a large amount of ALMA Compact Array data for the El Gordo cluster (over 40h) and make a map, to see if there is any hint of a shock or other structures. We shall then do some model fitting in the uv-plane.
- Lensed CIB profile for a cluster: we will use a simple lensing model for a cluster for analytically predict how the flux amplification profile will look like from lensing the Cosmic Infrared Background (CIB).
Galaxy evolution, ISM and Star Formation
- Hydrogen Recombination Lines (H-RL). Harvest the ALMA archive for observations of mm-wavelength hydrogen recombination lines (H-RL), determine the line fluxes and relate that to the infrared-flux, in order to establish H-RLs as reliable tracers of the massive star formation rate. We have a unique software developed for this be a recent master student that you will inherit, so you get a quick start.
- JWST MIRI. To study star formation and the dense ISM, through their PAH and line emission, in a representative sample of high-redshift (z=1-3) galaxies, we plan to propose for integral field spectroscopy (5 to 29 micron) observations with the MIRI instrument on JWST. The galaxies are selected from our ALMA spectroscopic deep field observations. The project supports the target selection and observation planning.
