  1. 1. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Chinmaya Nagar; [2023]
    Nyckelord :Emission-line ratio; Gaussian convolution; Green pea galaxies; ISM; Ionised ISM; Lyman continuum LyC ; Low-Redshift Lyman Continuum Survey LzLCS ; Lyman continuum emitter LCE ; LyC escape; LyC escape fraction; MUSE; MPDAF; Voronoi binning;

    Sammanfattning : Lyman continuum (LyC) photons are known to be responsible for reionising the universe after the end of the Dark Ages, which marked a period called the Epoch of Reionisation (EoR). While these high-energy photons are thought to predominantly originate from young, hot, massive stars within the earliest galaxies, and contributions from high-energy sources like quasars and AGN, the origins of these photons are yet not well known and highly debated.

    Sammanfattning : Visual tracking is a computer vision problem where the task is to follow a targetthrough a video sequence. Tracking has many important real-world applications in several fields such as autonomous vehicles and robot-vision. LÄS MER

  4. 3. Artifacts handling and DBS electrodes localization in the CT/MRI brain images

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Amir Motevakel; [2013]
    Nyckelord :;

    Sammanfattning : In the DBS surgical treatment  the location of the electrodes has direct influence on the success rate of treatment.  Considering the fact that MRI imaging is not compatible with metal, post-operative CT images should be used to locate the electrodes on pre-operative MRI images which contain information about soft tissues.
