1. Search for Higgs bosons in Z⁰ decays using the Delphi detector
Sammanfattning : .... LÄS MER
2. Observations of distant supernovae and cosmological implications
Sammanfattning : Type Ia supernovae can be used as distance indicators for probing the expansion history of the Universe. The method has proved to be an efficient tool in cosmology and played a decisive role in the discovery of a yet unknown energy form, dark energy, that drives the accelerated expansion of the Universe. LÄS MER
3. Characterizing the X-ray Properties of Clusters of Galaxies
Sammanfattning : Clusters of galaxies are the most massive bound structures known and represent a fair sample of the baryonic and dark matter content of the universe. The hot baryonic gas present in cluster dark matter halos cause them to emit in the X-ray band. LÄS MER
4. The Circumstellar Environment of Type Ia Supernovae
Sammanfattning : Type Ia supernovae (SNe Ia) have proven to be extremely useful for measuring cosmological distances and were used for the discovery of the accelerated expansion of the universe. Although thousands of SNe Ia have been observed to date, many questions surrounding the physics of the explosions and the nature of their progenitor systems remain unanswered. LÄS MER
5. Type Ia Supernova Cosmology : Quantitative Spectral Analysis
Sammanfattning : Type Ia supernovae have been successfully used as standardized candles to study the expansion history of the Universe. In the past few years, these studies led to the exciting result of an accelerated expansion caused by the repelling action of some sort of dark energy. LÄS MER
