  1. 16. Mass-Singularity Structure of QED and Perturbative Quantum Gravity Scatterings

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Santiago Londono Castillo; [2020]
    Keywords : perturbative quantum gravity; QED; mass singularities; collinear singularities; soft singularities; singularity cancellation; graviton; Physics and Astronomy;

    Abstract : In this thesis, the mass singularities occurring in the cross-section of electron scattering processes are investigated. Two types of scatterings are studied: Quantum Electrodynamics (QED) scatterings, and Perturbative Quantum Gravity (PQG) scatterings. READ MORE

  3. 17. 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

  4. 18. Synergies between Gaia, LSST and LISA

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Isabella Danaliv; [2020]
    Keywords : Gaia; LSST; LISA; telescope; synergies; multi-messenger; Physics and Astronomy;

    Abstract : The scientific development of astronomy today mainly comes from the information that can be obtained via electromagnetic radiation. Today, the Gaia optical telescope is one of the most ambitious space projects man has ever completed. Another optical telescope LSST is designed to complement Gaia. READ MORE

  5. 19. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Pablo Martinez Cano; [2019]
    Keywords : LISA; PCB; temperature; passive; aluminum; aluminium;

    Abstract : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.
