  1. 1. Resolving the smallest scale of star formation at Cosmic Noon with JWST : Star-forming clumps in a galaxy lensed by Abell 2744

    University essay from Stockholms universitet/Institutionen för astronomi

    Author : Annalena Pless; [2023]
    Keywords : star formation; star-forming clumps; galaxy evolution;

    Abstract : At higher redshift galaxies exhibit increasingly irregular and clumpy morphologies, withstar-forming clumps dominating the FUV output of their host galaxies thus being inti-mately related to star formation and the formation and evolution of galaxies. This workexamines star-forming clumps in a remarkable, young spiral galaxy at Cosmic Noon witha redshift ofz= 2. READ MORE

  3. 2. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

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

    Author : Þóra Karlsdóttir; [2023]
    Keywords : Dwarf Galaxy; Milky Way; Physics and Astronomy;

    Abstract : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations.

  4. 3. Colliding Galaxies in a (Nut)Shell

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Jonathan Petersson; [2022]
    Keywords : shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

    Abstract : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

  5. 4. Brightest Cluster Galaxies in the Local Universe: Mergers, Interactions and the Implications for Galaxy Evolution

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Diane Delley; [2022]
    Keywords : Brightest Cluster Gallaxies; BCG; Cosmology; Clusters of Galaxies; Merger; Interaction;

    Abstract : Clusters of Galaxies are amongst the largest gravitationally bound structures in our Universe and consist of thousands of galaxies. It is in these gigantic systems where Brightest Cluster Galaxies (BCGs) are found, the most massive galaxies in our Universe. A BCG, as its name indicates, is the brightest galaxy in a cluster.

  6. 5. Constraints on the High-Energy Gamma-Ray Spectrum of Nearby Star-Forming Galaxies

    University essay from Stockholms universitet/Fysikum

    Author : Oskar Svenborn; [2021]
    Keywords : Gamma-ray emission; High-Energy astrophysics; Star-Forming Galaxies; Star formation; Cosmic rays; Fermi-LAT.;

    Abstract : The nature of high-energy gamma-ray emission from Star-Forming Galaxies is of utmost importance for understanding both the origin of Cosmic Rays and the high-energy processes that shape galaxy formation. Observations from the gamma-ray telescope Fermi-LAT have detected gamma-ray emission from a handful of nearby Star-Forming Galaxies. READ MORE
