Everything here appears in anti-chronological order, which should be more or less in order of interest. This is not guaranteed though.

Master's Thesis: Star Clusters in M51

M51 In this project we investigated several aspects of the star clusters in M51, mainly related to their luminosities and radii. Broadband imaging observations (in this case HST/ACS, B,V and I imaging) on a small wavelength range are not sufficient to in detail derive ages, masses, extinctions and metallicity for all clusters separately. Therefore, it may be wise to only look at the statistics of the population, like radius distributions, luminosity functions and correlations between radius and magnitude (which both can be derived from the data, of course). So, that's what we did and some quite nice results followed from it.

If you want to know more about this subject, see some of the oldest publications in the publications section, or ask me! Asking in person is ofcourse also allowed...;-)

The final Masterpiece, my thesis, deals with some of the aspects of the radii and luminosities of star clusters in M51. Well... final? My paper about this actually came out more than two years after graduating...

Master Courses

In my fourth year I followed a course on General Relativity, of which this report on gravitational lensing by cosmic strings marked the end.

The only course more or less related to my later work was about galaxies. A report on synthetic spectral modeling of galaxies resulted from this.

The course on stellar mass loss culminated in an abstract about the research of the influence of stellar mass loss on the evolution of star clusters.

Bachelor related texts

I also did a small research project in Solar Physics. I went to La Palma to the Dutch Open Telescope for that. A small report on my 'findings' can be found here.

A report on the calculation of the velocity distribution of particles in gasses at extremely high temperatures, which I've written during my third year.

A report on the analysis of the X-ray spectrum of an AGN, using SPEX. Also third year stuff.

A text on the numerical integration of partial differential equations from my second year.

A text on some methods used in observational astrophysics, belonging to the corresponding second year course.
