  1. 26. Planes of satellite galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Jessica Laura Erika Kocher; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. READ MORE

  3. 27. On The Run: How Fast Runaway Stars Can Escape From Their Home Cluster?

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Anna-Maria Söderman; [2022]
    Keywords : star cluster; runaway stars; velocity distribution; Physics and Astronomy;

    Abstract : Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. READ MORE

  4. 28. Simulation of a prototype of the LDMX hadronic calorimeter and analysis of test beam data

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Péter György; [2022]
    Keywords : LDMX; HCal; TS; prototype; Physics and Astronomy;

    Abstract : The Light Dark Matter eXperiment (LDMX) is an upcoming experiment to test the existence of dark matter in the mass range of 1 MeV - 1 GeV. It does so by looking for missing momentum and energy in collisions of an electron beam and a tungsten target, which could potentially indicate the existence of dark matter. READ MORE

  5. 29. Improvement of the Rucio implementation for the LDCS platform and search for dark data

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Piotr Yartsev; [2022]
    Keywords : Dark matter; rucio; digital infrastructure; Root; LDMX; LDCS; dark data; Python; CERN; particle physics; big data; Geant4; Light Dark Matter eXperiment; Lightweight Distributed Computing System; data storage; Physics and Astronomy;

    Abstract : In this work we aim to implement a software package to detect and categorize dark data, data not accessible or not known by the user, generated in the simulations of the Light Dark Matter eXperiment (LDMX). This will involve studying current existing solutions for such problems, attempting to implement them for the Lightweight Distributed Computing System (LDCS), and developing our own Dark Data Search (DDS) toolkit to perform the detection and categorization of the dark data.

  6. 30. Rejection of the Photon Induced Background in LDMX at 8 GeV

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Erik Wallin; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The Light Dark Matter eXperiment (LDMX) is a proposed fixed target experiment at SLAC's LCLS-II electron beamline that will attempt direct production of sub-GeV dark matter, measurable through a missing momentum and missing energy signature. An initial run of LDMX is planned at 4 GeV beam energy, for which a study on LDMX's capabilities to separate dark matter production events from the standard model background was previously performed.
