Mass and radius constraints for neutron stars from pulse shape modeling
Neutron stars are the most compact directly observable objects. The matter inside a neutron star is at supranuclear densities. The equation of state (EOS) of neutron stars describes the properties of such dense matter. ...
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 ...
Globular Cluster Bimodality in Isolated Elliptical Galaxies

Examining the symmetry of optical flares in blazars
Blazars are one of the most energetic types of active galactic nuclei. They are luminous emitters that can be detected over the whole of the electromagnetic spectrum. They are radio-loud objects whose jet is closely aligned ...
Magnetospheric truncation of an accretion disk around the unique X-ray pulsar GRO J1744-28
(Turun yliopisto, 2017-09-18)
Neutron stars are very massive yet compact objects, where both quantum mechanical and relativistic effects play a role. Many of them have magnetic fields which are many orders of magnitude stronger than what mankind can ...
Constraining supernova progenitors with integral field spectroscopy
Core-collapse supernovae (CCSNe) are an important part of the stellar evolution of massive stars. Certain types of supernova (SN) explosions are believed to originate from similar types of stars, but linking a SN type ...
Symplektisen integroinnin soveltaminen satelliittien suhteellisten ratojen laskemiseen
(Turun yliopisto, 2009-10-07)
Maapalloa kiertävien satelliittien liikkeet toistensa suhteen eli satelliittien suhteelliset radat ovat keskeisessä asemassa satelliittimuodostelmien kannalta. Suhteellisten ratojen ratkaiseminen maapallon potentiaalikentässä ...
A Study of Astronomical Polarization, Polarimetric Observations and Polarimetry of Exoplanets
Astronomical polarization has become one useful tool to study a number of astronomical objects and related astrophysical mechanisms. The polarization of electromagnetic waves is caused by various astronomical phenomena. ...
