  1. 1. Constraining the Potential of the Milky Way using Stellar Streams

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Timmy Ejdetjärn; [2017]
    Keywords : stellar streams; Milky Way; potential; confidence region; orbital approximation; MW; CR; halo; disc; constrain; mass; orbit; simulation; simulated; fitting; likelihood; Physics and Astronomy;

    Abstract : The orbital approximation for stellar streams is the assumption that all stars in a stream can be described as following the same orbit. In this thesis, I evaluate this approximation as a method for constraining the potential of the Milky Way. READ MORE

  3. 2. Fusion of IMU and Monocular-SLAM in a Loosely Coupled EKF

    University essay from Linköpings universitet/Reglerteknik

    Author : Fåhraeus Henrik; [2017]
    Keywords : loosely coupled EKF; monocular slam; calibration of camera and IMU; EKF; gravitation error;

    Abstract : Camera based navigation is getting more and more popular and is the often the cornerstone in Augmented and Virtual Reality. However, navigation systems using camera are less accurate during fast movements and the systems are often resource intensive in terms of CPU and battery consumption. READ MORE

  4. 3. Updating bounds on the low-energy constants of Chiral Perturbation Theory from exact bounds on amplitudes

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

    Author : Benjamin Alvarez; [2016]
    Keywords : Coupling constants; meson-meson scattering; Chiral perturbation theory; constraints.; Physics and Astronomy;

    Abstract : Chiral perturbation theory is an efficient effective theory to describe meson-meson scattering at low energy. An effective theory naturally introduces low energy constants and they are used, for example, to solve the ultraviolet divergences. READ MORE

  5. 4. Tidal Streams as a Probe of the Milky Way Assembly History

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

    Author : Espen Kirkesæther Brun; [2016]
    Keywords : Astrophysics; Astronomy; Dynamics; Galactic; Tidal Streams; Stellar Streams; Dark Matter; Subhalos; Physics and Astronomy;

    Abstract : The current Lambda Cold Dark Matter cosmology predicts galaxy growth by hierarchical merging, leading to galaxy substructure like tidal streams and dark matter subhalos devoid of stars. The goal of this thesis is to investigate whether tidal stream-subhalo interactions can leave observable gaps in the streams, and at which rate this might happen in a galaxy like the Milky Way.
