  1. 11. Black Holes of the First Stars

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Aron Kordt; [2022]
    Keywords : ;

    Abstract : In this report, we constrain properties of foreground objects in the Milky Way that have the potential of being confused with accretion disks of Population III stellar- mass black holes at high redshift. Following Windhorst et al. (2018), a model for multicolour accretion disks of Population III stellar-mass black holes is presented. READ MORE

  3. 12. Fermi-LAT gamma-ray and multi-wavelength SED analysis and modelling of PKS 0426-380 : A thesis analysing the behaviour and properties of the blazar PKS 0426-380

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Nathanael Löfström; [2022]
    Keywords : active galactic nucleus; black hole; AGN; Fermi-LAT; JetSeT;

    Abstract : An analysis is made on the Flat Spectrum Radio Quasar PKS 0426-380 using two sets of data. The first set of data is the Fermi-LAT data collected over the time 54682.66 − 59317.66 in Modified Julian Date within the energy range of 100 MeV to 500 GeV. READ MORE

  4. 13. Black Hole Dynamics in Stellar Clusters

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Markus Strickert; [2022]
    Keywords : Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

    Abstract : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

  5. 14. Black Holes and Scalar Fields : A study of a massive scalar field around a black hole

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Abdulmasih Ghazal; [2022]
    Keywords : Black holes; scalar field; General relativity; special relativity; spacetime; cosmology; Schwarzschild; Schrödinger equation; Svart hål; relativitetsteori; skalär fält; rumtid; Shrödinger; Schwarzschild.;

    Abstract : Black holes are one of the most interesting objects in the universe, and studying these objects should give exciting results. This research will investigate the General Theory of Relativity, explaining the essence of the theory needed for deriving solutions for a Schwarzschild black hole. READ MORE

  6. 15. Review of Black-hole Amplitudes

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Chen Huang; [2022]
    Keywords : ;

    Abstract : Abstract: In this review, we referred to several recent works about the black-hole amplitudes. By regarding the black holes as elementary particles, we wrote down the amplitudeswhich describe the black-hole graviton scattering. READ MORE
