On the 29th of October, our colleague Sarrvesh Sridhar successfully defended his thesis "Non-thermal emission and magnetic fields in nearby galaxies" at the University of Groningen. His thesis is the culmination of a herculean effort to characterise polarisation observations of nearby galaxies conducted by LOFAR in a time when the instrument was far from simple to calibrate and understand. The work has been particularly important in understanding particle acceleration processes in galaxies similar to our own Milky Way. We can add that his thesis also includes LOFAR images of some of the most iconic nearby spiral galaxies, well studied in the past at other radio (and not only!) wavelengths by many people over the years at both the Kapteyn Institute and ASTRON. Sarrvesh was supervised by Dr George Heald and Prof. Thijs van der Hulst (official promoter). Sarrvesh is currently a telescope scientist at ASTRON. You can access his thesis here (or you can ask him for a hardcopy).
