  1. 31. Study of Dark Matter Models in Astrophysics and Particle Physics

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

    Författare :Isabelle John; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : From astrophysical and cosmological observations, it is known that most of the matter in the Universe is dark. This matter could be explainable by new particles, not included in the Standard Model of Particle Physics. LÄS MER

  3. 32. MAC-E-Filter characterization for PTOLEMY : a relic neutrino direct detection experiment

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Carl-Fabian Strid; [2019]
    Nyckelord :particle physics; astroparticle physics; astrophysics; PTOLEMY; relic neutrinos; monte carlo simulation; mac-e-filter; sterile neutrinos; physics beyond the standard model;

    Sammanfattning : The cosmic neutrino background (CNB) can be composed of both active and hypothetical sterileneutrinos. At approximately one second after big bang, neutrinos decoupled from radiationand matter at a temperature of approximately one MeV. LÄS MER

  4. 33. Interpreting density enhancement of coronal mass ejections

    Kandidat-uppsats, Uppsala universitet/Rymd- och plasmafysik

    Författare :Kellen Smith; [2019]
    Nyckelord :physics; astrophysics; coronal mass ejection; WSA-ENLIL Cone; arrival time; prediction; model parameters; fysik; astrofysik; koronamassutkastning; WSA-ENLIL Cone; ankomsttid; prognos; modellparametrar;

    Sammanfattning : Coronal mass ejections (CMEs) are some of the extraterrestrialevents most impactful to earth. Eorts to model and predict theireects have seen new possibilities in the two most recent decades dueto multiple new spacecrafts providing a wider range of data than everbefore. LÄS MER

  5. 34. A System for Cross-matching All-sky Surveys

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Johan Soodla; [2019]
    Nyckelord :VASCO; Big Data; Cloud; Cross-matching; SETI; Machine Learning;

    Sammanfattning : This thesis describes the cross-matching software solution lying at thecore of the computational infrastructure for the VASCO project. The VASCO project has a goal to mine historical all-sky surveys to find astronomical anomalies. LÄS MER

  7. 35. Studies of the orbital background noise and the detector characteristics for the MeVCube mission

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Eleni Athanasiou; [2019]
    Nyckelord :space instrumentation; gamma-ray instrumentation; MeVCube; space environment effects; orbital background noise; detector characteristics; signal generation; weighting potential simulations; electric field simulations;

    Sammanfattning : A space camera is a promising candidate to address the non-stop rising interest for astrophysics research in the Compton regime. The MeVCube mission is intended to be launched in 2022, hosting an on-board Compton Camera. LÄS MER
