Variability of radio and TeV emitting X-ray binary systems: The case of LS I +61°303
(2013-09-09)
X-ray binaries contain a compact object, a black hole or a neutron star, and a normal companion star. An exclusive club of only ∼5 sources, also emits in radio and in gamma-rays. The nature of these gamma-ray binaries is ...
Investigating astrophysical plasmas with pulsars using LOFAR and other telescopes
(2015-02-19)
Pulsars are rapidly-rotating, highly-magnetised neutron stars that produce radio emission in their magnetospheres, which is detected as pulses on Earth. The focus of this thesis is observing pulsars as the means to study ...
The Physical Properties of Intermediate-Velocity Gas at High Galactic Latitudes
(2016-07-26)
The accretion of matter onto galactic disks, the formation of molecular clouds, and the formation of stars are of major importance for the evolution of galaxies over cosmic times. During their lifetimes, high-mass stars ...
Dust and gas in the MilkyWay: a full-sky view on the multiphase interstellar medium
(2016-11-04)
The Milky Way (MW) Galaxy is a unique laboratory to study the evolution of spiral galaxies, offering great sensitivities and angular resolutions with respect to observations of other galaxies. There, the large distance and ...
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.
The current approach to large-scale HI surveys, ...
