1. Investigating the origin of radio emission in nearby starburst galaxies via high-resolution metre and centimetre observations
Sammanfattning : Star formation and galaxy evolution are intimately linked together. A detailed understanding of the physics of star formation can help us explain how galaxies evolve into, for example, our present Milky Way. LÄS MER
2. Multi frequency interferometer studies of active and starburst galaxies
Sammanfattning : We report the results of a multi-frequency study of three interactinggalaxies: NGC 5218, NGC 1614 and NGC 4194 (the Medusa merger). These sourcesbelong to different classes of active and starburst galaxies. LÄS MER
3. Stacking of interferometric data at sub-millimeter and radio wavelengths
Sammanfattning : Understanding the procceses of galaxy evolution require observational constraints on the physical properties of galaxies at different times in the history of the Universe. Large and deep surveys at visible and near-infrared wavelengths have, during the past decade, been used to produce extensive catalogues of high-redshift galaxies, spanning a large range of the history of the Universe.

4. Molecular gas and ionizing radiation in star-forming galaxies
Sammanfattning : In cosmic history, some of the major changes such as reionization were driven by baryons (i.e. the stars and gas in galaxies), despite the fact that they contribute only few percent to the total mass-energy budget in the Universe. LÄS MER
5. Polarization in the ELAIS-N1 LOFAR deep field
Sammanfattning : The physical characteristics of cosmic magnetic fields are encoded in the po- larization properties of the extragalactic radio sources. Linearly polarized radiation undergoes Faraday rotation as it crosses a magneto-ionic medium; the rotation of the polarization angle of the signal is equal to its wavelength squared times the Rotation Measure (RM), that is proportional to the line- of-sight integral of the product of the magnetic field component along the line of sight and the density of thermal electrons.
