  1. 11. Statistical analysis of LDMX data

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Noah Ritter; [2023]
    Nyckelord :LDMX; dark matter; light dark matter; statistics; hypothesis testing; ROOT; Physics and Astronomy;

    Sammanfattning : This thesis explores a statistical framework for analysing LDMX data. It uses pre-built functions in the ROOT framework to calculate likelihoods and confidence levels (CL). LÄS MER

  3. 12. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Daniel Álvarez Franco; [2022]
    Nyckelord :Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

    Sammanfattning : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. LÄS MER

  4. 13. Dancing and learning about astrophysics : A case study on user behavior of students in Sweden using TikTok and the app's impact on their lives

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alper Kaya; [2022]
    Nyckelord :Words: s ocial media; TikTok; algorithm; user behavior; persuasive technology; privacy; case study; s ociala medier; TikTok; algoritm; användarbeteende; pers uasive technology; integritet; fallstudie;

    Sammanfattning : The social media app TikTok, owned by the Chinese Company ByteDance, has become a worldwide success with over one billion monthly active users due to an algorithm that enables users to consume individually tailored content. However, it was also part of pol itical confrontations between countries like the USA and China due to allegedly security risks. LÄS MER

  5. 14. Detecting Transiting Exoplanets in Crowded Fields

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Eddie Larsson; [2022]
    Nyckelord :Transit method; Globular cluster; crowded environments; exoplanets; transiting exoplanets; Physics and Astronomy;

    Sammanfattning : The first planet orbiting a main-sequence star was discovered in 1995. Since then more than 4000 additional exoplanets have been discovered. This is a rapidly evolving field in astrophysics. One of the most common ways to detect an exoplanet is through transit, as the brightness of the host star decreases. LÄS MER

  7. 15. A Cosmic View of Life on Earth : Visualizing the relationship between species DNA in a threedimensional space

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Emma Segolsson; Linn Storesund; [2022]
    Nyckelord :visualization; DNA; openspace; primates; barcodes; PCA;

    Sammanfattning : This master thesis project is interdisciplinary between the fields of biology, visualization, and astrophysics. The project was conducted at the American Museum of Natural History in New York in collaboration with researchers from Basel, Switzerland. LÄS MER
