  1. 1. Intermediate-mass black hole binary as an origin of super-massive black holes

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Isabelle Signe Maj Maria Thord; [2023]
    Keywords : Intermediate-mass black holes; binary; merger; hardening; encounters; Physics and Astronomy;

    Abstract : Galactic nuclei contain super-massive black holes (SMBHs), nuclear stellar clusters (NSCs), or both. In the NSC, intermediate-mass black holes (IMBHs) are likely to reside and form highly eccentric binaries. Over time, the orbit of a binary could harden via interaction with surrounding low-mass stars. READ MORE

  3. 2. The retention of black holes in globular clusters

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

    Author : Wuxueman Liu; [2021]
    Keywords : Physics and Astronomy;

    Abstract : We simulate the velocities of formed Black Holes to determine the fraction of retained Black Holes in 152 Globular Clusters. The model we used for the escape velocity is from Plummer. The scenarios of the natal kick are Neutronstar like kicks and momentum conserving kicks. READ MORE

  4. 3. Chaos in Stellar Dynamics - Outcomes of Binary-Single interactions in Globular Clusters

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

    Author : Lucas Hellström; [2020]
    Keywords : Stellar Dynamics; Binary-Single interactions; Dynamical encounters; Additional processes; Physics and Astronomy;

    Abstract : Gravitational encounters between a single star and a binary system can frequently occur in the cores of dense stellar systems like globular clusters. These three-body scattering encounters can lead to a variety of outcomes since the energy of the binary components can be exchanged with the interacting single star. READ MORE

  5. 4. The information paradox - Horizon structures and its effects on the quasinormal mode gravitational radiation from binary merger ringdowns : Gravitational echoes from reflective near horizon structures

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Anton Vikaeus; [2017]
    Keywords : information paradox; gravitational waves; horizon structures; binary black hole merger; quasinormal modes; QNM; gravitational echoes;

    Abstract : Classical theory cannot provide a satisfying scenario for a unitary thermodynamic evolution of black holes. To preserve information one requires quantum mechanical effects on scales reaching beyond the traditional horizon radius. READ MORE

  6. 5. Gravitational Waves and Coalescing Black Holes

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Joanna Ekehult; Anna Karpinska; [2017]
    Keywords : ;

    Abstract : Gravitation is a manifestation of the space-time curvature and gravitational waves aredistortions traveling through the fabric of space-time. Scientists have tried to detectgravitational waves for decades, but the first direct detection of gravitational waves andthe first observation of a binary black hole merger was made in 2015. READ MORE
