Statistical Analyses of Massive Stars and Stellar Populations
(2015-03-04)
Massive stars, i.e. stars more massive than about ten times that of the Sun, are key agents in the Universe. They synthesise many of the chemical elements that are so important for life on Earth, helped reionising the early ...
Statistical properties of cosmological correlation functions
(2015-04-24)
Correlation functions are an omnipresent tool in astrophysics, and they are routinely used to study phenomena as diverse as the large-scale structure of the Universe, time-dependent pulsar signals, and the cosmic microwave ...
Challenges of theoretical and numerical structure formation in a ΛCDM universe
(2015-06-22)
Systematic surveys of the extra-galactic sky have revealed the existence of large-scale structures in the Universe: the galaxy distribution is organized in a complex network of filaments surrounding underdense regions and ...
Galaxies in Milgromian Dynamics
(2015-02-04)
Since its first formulation in 1983, Milgromian dynamics (also known as modified Newtonian dynamics or MOND) has been very successful in predicting the gravitational potential of galaxies from the distribution of baryons ...
Investigating Anisotropies in the Local Universe with Type Ia Supernovae from the Nearby Supernova Factory
(2015-12-10)
The dipole anisotropy of the cosmic microwave background temperature is two orders of magnitude larger than its other multipole components, which is attributed to the Doppler shift due to the motion of our Local Group of ...
Automated Source Extraction for the Next Generation of Neutral Hydrogen Surveys
(2015-12-23)
This thesis is a first step to develop the necessary tools to automatically extract and parameterize sources from future HI surveys with ASKAP, WSRT/Apertif, and SKA.
