  1. 1. Measuring copper abundances in the Galactic Bulge

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Nikolei Höglinger; [2024]
    Nyckelord :Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Sammanfattning : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  3. 2. Skumtroll och vårskrik över mediegränser : En intermedial studie av Ronja Rövardotter om överskridanden mellan människa, språk och natur

    Master-uppsats, Linnéuniversitetet/Institutionen för film och litteratur (IFL)

    Författare :Åsa Nyfeler; [2023]
    Nyckelord :Ronja rövardotter; Ronja Rövardotter; Astrid Lindgren; intermedial; intermedialitet; intermediala studier; Lars Elleström; adaptionsstudier; medietransformation; transmedialitet; transmedial; transmediering; skumtroll; vårskrik;

    Sammanfattning : This master's thesis investigates the transmediations of Astrid Lindgren's Ronja the Robber's Daughter into a feature film by Tage Danielsson and an anime by Goro Miyazaki. Drawing on intermedial theory and analytical method, the analysis explores how the creatures called “murktrolls” and Ronja’s “scream of spring” are portrayed across these media adaptations. LÄS MER

  4. 3. Hyper-velocity stars from globular clusters hosting intermediate-mass black holes

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Matilda Skantz; [2023]
    Nyckelord :Hypervelocity stars; run-away stars; stellar binary; intermediate mass black hole; globular cluster; Hills mechanism; Physics and Astronomy;

    Sammanfattning : In 1988 Hills proposed that stars can gain velocities above 500 km s−1 if they are in a stellar binary which gets disrupted by a super massive black hole (SMBH). One of the stars would get trapped in an elliptical orbit around the SMBH while the other gets ejected and obtains a relatively high velocity. LÄS MER

  5. 4. Searching for direct collapse black holes using the James Webb Space Telescope

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

    Författare :Edison Arellano Almeida; [2022]
    Nyckelord :extragalactic astronomy;

    Sammanfattning : Recent detections of massive quasars at z > 6 has proven to be an interesting challengefor cosmology given the short time frame that these objects have to reach a certainmass via conventional methods (e.g., galaxy mergers). LÄS MER

  7. 5. Black Holes of the First Stars

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

    Författare :Aron Kordt; [2022]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
