MeerGas is a project to study how galaxies acquire their neutral hydrogen gas. Using the MeerKAT radio synthesis telescope in South Africa, we are obtaining ultra-deep observations of the neutral hydrogen in 30 nearby galaxies (as part of the MeerKAT MHONGOOSE Large Science Project). We will use these to find and characterise signs of low-column density gas accreting onto these galaxies. MeerGas is funded by the European Research Council.

To help support the MeerGas project, we invite applications for a

Job description:

As part of the MeerGas team, you will help with reducing and analyzing the MeerKAT MHONGOOSE radio data. You will help expand the capabilities of the data reduction and analysis pipelines. You will explore novel techniques to explore this unique MeerKAT data set, also through participation in the ASTRON Science Data Centre. You will lead one of the science projects within MeerGas with the ultimate goal to determine the nature of cold gas accretion in galaxies.

You will be part of a team consisting of a number of postdocs and students. You will collaborate with the MHONGOOSE team, consisting of many international experts on spectral-line and multi-wavelength observations. You will also work with the MeerKAT team in South Africa. The position will be full-time (38 hours per week).

Junior commissioning engineer

During my graduation project for the study of astronomy, I had my first encounter with ASTRON. At that time I got the chance to make an interesting thesis I seized the opportunity immediately! After my studies I started to work at ASTRON. I chose ASTRON partly because it is a knowledge institute. There is also […]
