1. Molecular clouds and star formation in galaxies
Sammanfattning : .... LÄS MER
2. The Frequency of Supernovae in the Early Universe
Sammanfattning : Supernovae are cosmic explosions of cataclysmic proportion that signify the death of a star. While being interesting phenomena in their own right, their brightness also make them excellent probes of the early universe. Depending on the type of the progenitor star and the origin of the explosion different subjects can be investigated. LÄS MER
3. Observing Lyman alpha emitters - How does Lyman alpha escape from galaxies?
Sammanfattning : The Lyman alpha (Lyα) emission line has grown to become one of the most successful tools for finding galaxies at high redshift. At redshifts corresponding to the early cosmic times of reionization and primeval galaxy formation, the wavelength of Lyα is still accessible with ground-based facilities. LÄS MER
4. A High Resolution Study of the LINER Galaxy NGC5218
Sammanfattning : Low Ionisation Nuclear Emission-line Regions (LINERs)are found in one third of the galaxies in the local bright galaxy population. The LINERs typically recide in the central parts of their host galaxies, and occur in early type elliptical galaxies as well as late type spiral galaxies. LÄS MER
5. A study of the Hercules dwarf spheroidal galaxy
Sammanfattning : Parts of large spiral galaxies, such as the Milky Way and Andromeda, are believed to have formed from the accretion of several smaller galaxies. Remnants of this chaotic merging era, such as dwarf spheroidal (dSph) galaxies, are visible in the outskirts of large galaxies. LÄS MER
