Activity and dust environment of comet 67P/Churyumov-Gerasimenko
(Turun yliopisto, 2018-06-01)
Comets are scientifically interesting objects for several reasons. Comets are among the most pristine objects of the Solar System, which can give us a way to directly study the imprints of the Solar System formation ...
Mass and radius constraints for neutron stars using X-ray timing, spectral, and polarization observations
(Turun yliopisto, 2020-12-11)
Neutron stars (NSs) are the most dense objects in the Universe that can be directly observed. The nature of the cold ultra-dense matter inside them is still unresolved, and determining the equation of state (EoS) of that ...
Controlling dynamics of open quantum systems
(Turun yliopisto, 2019-10-05)
Quantum mechanics has both deepened our understanding of the physical reality and allowed development of quantum technologies beating their classical counterparts in efficiency, security, and sensitivity. As a major downside, ...
Bl lac objects - view from the highest energies
(Turun yliopisto, 2020-06-16)
Relativistic jets launched by a super-massive black holes are among the most extreme particle accelerators in the Universe. BL Lac objects host a relativistic jet that points very close to our line of sight. They are the ...
Measurement simulability and incompatibility in quantum theory and other operational theories
(Turun yliopisto, 2021-06-17)
Quantum theory is a particularly important instance of an operational theory.By looking at quantum theory from the perspective of more abstract operational framework one is able to study its properties in a wider context. ...
Transport in correlated open quantum systems
(Turun yliopisto, 2021-01-30)
The problem of the dynamics in open and correlated quantum systems has gained attention in recent years due to the impressive experimental advances that were made in quantum transport in molecular systems. The importance ...
Ab initio investigations of the durability of iron alloys and titanium
(Turun yliopisto, 2019-06-14)
In this ab initio work the oxidation of Fe-Cr, Fe-Al, Fe-Cr-V and Fe-Cr-Al, and the elasticity of Fe-Cr-Al alloys and titanium were investigated. The computational method used was Exact Muffin-tin Orbitals method (EMTO). ...
Empirical modelling of solar energetic particles
(Turun yliopisto, 2021-06-28)
Solar energetic particles (SEPs) are an important component of space weather. They pose a serious radiation hazard to electronic equipment and biological organisms in space. They are produced in explosive events such as ...
Properties of highly magnetized neutron stars from X-ray timing analysis on different time scales
(Turun yliopisto, 2022-10-26)
Massive stars end their lives either by collapsing directly into a black hole or by exploding as a supernova, leaving behind their collapsed core, a black hole or a neutron star (NS). NSs are a showcase of extremities: ...
Observational studies of accreting X-ray pulsars in a broad energy range
(Turun yliopisto, 2022-11-04)
Among all interesting astrophysical objects in the universe, only a few are capable of improving our understanding of physics under extreme conditions. Accreting neutronstars are one of these objects. These compact objects ...
