  1. 1. Energy reconstruction with artificial neural networks on LDMX simulations

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

    Författare :Daniel Magdalinski; [2020]
    Nyckelord :Dark matter; LDMX; electromagnetic calorimeter; neural networks; convolutional neural networks; Physics and Astronomy;

    Sammanfattning : It is clear from evidence such as rotational curves and cosmic microwave background measurements that dark matter exists. The light dark matter experiment (LDMX) will search for dark matter in the sub-GeV range. It will do this using missing-momentum measurements of electrons interacting with a Tungsten target. LÄS MER

  2. 2. Test setup for LDMX HCal readout

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

    Författare :Joshua Greaves; [2020]
    Nyckelord :Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Sammanfattning : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  3. 3. Thursatrún i Thursakyngi : Den vänstra handens väg genom den fornnordiska mytologin

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Författare :Maria Svartberg; [2020]
    Nyckelord :Thursatrú; Left-Hand Path; Chaos-gnosticism; Gnosticism; Satanism; Discourse; Old Norse Mythology; New Religions; Dualism; Anti-cosmic; Antinomian; Adversary; Sinister;

    Sammanfattning : Thursatrú is a spiritual tradition which combines ideas from the Left-Hand Path tradition and chaos-gnosticism with readings of the old Norse sagas. This essay is about thursatrú as it is pronounced in a trilogy of books called Thursakyngi. The methodology and theoretical viewpoints are mainly based on discourse-analysis. LÄS MER

  4. 4. Lyman Continuum Radiation from Intermediate-Mass Black Holes : An Estimation of the Contribution of LyC Radiation from IMBHs in z~3 Galaxies

    Kandidat-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Marika Ljungberg; [2020]
    Nyckelord :intermediate-mass black holes; cosmic reionization; high-redshift galaxies;

    Sammanfattning : This thesis concerns the cosmic reionization of the intergalactic medium in the high redshift universe and, in particular, is a first approach to examine what role intermediate mass black holes (IMBHs) play in this cosmic age. Unexpectedly high values of hydrogen ionizing radiation, compared to current models, have been reported from galaxies at redshift ~3 (used as stand-ins for galaxies at the age of reionization), and thus these models need revision, potentially by adding effects of IMBH content in the galaxies.

  5. 5. Kosmiska Neutriner

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Lara Mohatadi; Rasoul Lasek; [2020]
    Nyckelord :;

    Sammanfattning : Neutrinoobservationer kan ge mycket information om vad som händer ute i rymden. Den observationen och studien som ger den mest konkreta informationen är smaksammansättningar av neutriner som når jorden efter att den propagerat i rymden från dess källa. LÄS MER
