Numerics of Spacecraft Dynamics
(Turun yliopisto, 2011-02-26)
Whenever a spacecraft is launched it is essential that the algorithms in the on-board software systems and at ground control are efficient and reliable over extended periods of time. Geometric numerical integrators, and ...

Studies of Eu- and Yb-induced Reconstructions on the Si(100) Surface
(Turun yliopistoAnnales Universitatis Turkuensis A I 387, 2008-12-19)
This thesis presents experimental studies of rare earth (RE) metal induced structures on Si(100) surfaces. Two divalent RE metal adsorbates, Eu and Yb, are investigated on nominally flat Si(100) and on vicinal, stepped ...

(Turun yliopistoAnnales Universitatis Turkuensis A I 556, 2017-04-21)
Einstein's theory of general relativity is without doubt one of greatest achievements in the history of Mankind. Even so, there are some ways, in which it leaves room for improvement. The last one hundred ...
On the Properties and Cosmology of Q-balls
(Turun yliopistoAnnales Universitatis Turkuensis AI 272, 2001)
The properties and cosmological importance of a class of non-topological solitons, Q-balls, are studied. Aspects of Q-ball solutions and Q-ball cosmology discussed in the literature are reviewed. Q-balls are particularly ...

X-ray bursts as a tool to constrain the equation of state of the ultra-dense matter inside neutron stars
(Turun yliopisto, 2017-12-15)
Neutron stars are one of the most dense objects in the Universe. However, the exact description of the equation of state (EoS) of the cold ultra-dense matter inside them is still a mystery. In this thesis, we measure the ...

Very High Energy Gamma-Rays emitting BL LAC's Population Study
(Turun yliopisto, 2014-09-16)
Context: BL Lacs are the most numerous extragalactic objects which are detected in Very High Energy (VHE) gamma-rays band. They are a subclass of blazars. Large flux variability amplitude, sometimes happens in very short ...
