Electron precipitation characteristics during isolated, compound, and multi-night substorm events
(Journal article; Peer reviewed, 2021)A set of 24 isolated, 46 compound, and 36 multi-night substorm events from the years 2008–2013 have been analysed in this study. Isolated substorm events are defined as single expansion–recovery phase pairs, compound ... -
Electroweak boson production in p–Pb and Pb–Pb collisions at \(\sqrt{s_\mathrm{NN}}=5.02\) TeV with ALICE
(Peer reviewed; Journal article, 2017-11)W and Z bosons are massive weakly-interacting particles, insensitive to the strong interaction. They provide therefore a medium-blind probe of the initial state of the heavy-ion collisions. The final results for the W and ... -

Elever sin bruk av forkunnskaper i faglige diskusjoner under praktisk arbeid i naturfag
(Master thesis, 2016-06-01)Forskning viser at elever mangler både kunnskaper og forkunnskaper. Forskning har også sett at elever har forkunnskaper, og at disse er nødvendige for videre kunnskapsbygging. For at elever skal kunne drøfte fysikk ... -
Elliptic and triangular flow of (anti)deuterons in Pb-Pb collisions at √sNN=5.02 TeV
(Journal article; Peer reviewed, 2020-11-17)The measurements of the (anti)deuteron elliptic flow (v2) and the first measurements of triangular flow (v3) in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon collision √sNN = 5.02 TeV are presented. A ... -
