    • Bl lac objects - view from the highest energies 

      Fallah Ramazani, Vandad
      Turun yliopiston julkaisuja - Annales Universitatis Turkuensis, Ser A I: : 628 (Turun yliopisto, 16.06.2020)
      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 ...

    • Environments of Active Galaxies 

      Lietzen, Heidi
      Turun yliopiston julkaisuja. Sarja AI, Chemica - Physica – Mathematica : 447 (Turun yliopisto, 10.11.2012)
      This dissertation presents studies on the environments of active galaxies. Paper I is a case study of a cluster of galaxies containing BL Lac object RGB 1745+398. We measured the velocity dispersion, mass, and richness ...

    • Mass and radius constraints for neutron stars using X-ray timing, spectral, and polarization observations 

      Salmi, Tuomo
      Turun yliopiston julkaisuja - Annales Universitatis Turkuensis, Ser A I: Astronomica, Chemica, Physica, Mathematica : 637 (Turun yliopisto, 11.12.2020)
      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 ...

    • X-ray bursts as a tool to constrain the equation of state of the ultra-dense matter inside neutron stars 

      Nättilä, Joonas
      Turun yliopiston julkaisuja. Sarja AI: Astronomica - Chemica - Physica – Mathematica : 570 (Turun yliopisto, 15.12.2017)
      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 ...
