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 ...
Michelson interferometer with porch swing bearing for portable FTIR spectrometer
(Turun yliopistoAnnales Universitatis Turkuensis A I 487, 2014-05-10)
The interferometer for low resolution portable Fourier Transform middle infrared spectrometer was developed and studied experimentally. The final aim was a concept for a commercial prototype. Because of the portability, ...
On Methods for Constraining F (R) Theories of Gravity
(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 ...
Small and Large Scale Dynamics in the Milky Way
(Turun yliopistoAnnales Universitatis Turkuensis A I 409, 2010-07-31)
This thesis contains dynamical analysis on four different scales: the Solar system, the Sun itself, the Solar neighbourhood, and the central region of the Milky Way galaxy. All of these topics have been handled through ...
Magnetic Resonance Experiments with Atomic Hydrogen
(Turun yliopistoAnnales Universitatis Turkuensis A I 412, 2010-10-30)
In this thesis three experiments with atomic hydrogen (H) at low temperatures T<1 K are presented. Experiments were carried out with two- (2D) and three-dimensional (3D) H gas, and with H atoms trapped in solid H2 matrix. ...
Properties of Galaxies and Groups: Nature Versus Nurture
(Turun yliopistoAnnales Universitatis Turkuensis A I 419, 2011-06-03)
Magnetic resonance study of atomic hydrogen stabilized in matrices of hydrogen isotopes below 1K
(Turun yliopistoAnnales Universitatis Turkuensis A I 555, 2017-03-03)
In this thesis, we report on an experimental study of H, D and T atoms stabilized in solid molecular matrices of hydrogen isotopes at temperatures down to 70 mK. Previous experiments have been carried out at ...
Observational studies of core-collapse supernova progenitors and their environments
(Turun yliopistoAnnales Universitatis Turkuensis A I 558, 2017-05-12)
In this doctoral thesis, core-collapse supernova progenitor stars are studied. Different ways to gain information on the progenitor stars of core-collapse supernovae are explored, with an emphasis on using the environments ...
