Gamma-ray observations of MAXI J1820+070 during the 2018 outburst
(Peer reviewed; Journal article, 2022)MAXI J1820+070 is a low-mass X-ray binary with a black hole (BH) as a compact object. This binary underwent an exceptionally bright X-ray outburst from 2018 March to October, showing evidence of a non-thermal particle ... -
GAMMA-RAYS FROM SPIDER BINARIES - A search for gamma-ray emission around the nearby compact binary millisecond pulsar PSR J1720-0533
(Master thesis, 2023)Fermi Large Area Telescope (LAT) har ført til en drastisk økning i antall oppdagede kompakte binære millisekundpulsarer i Melkeveien (også kjent som "spiders"). Majoriteten av de kjente spider-pulsarene viser gammastråle-emisjon, ... -
GAN Based Super-Resolution of Near-Surface 3D Atmospheric Wind Flow with Physics Informed Loss Function

Gauge Dependence of the Quantum Field Theory Effective Potential
(Master thesis, 2013)Using the absolute stability requirement of the Standard Model vacuum, we compute the Higgs mass bound for the 1-loop Standard Model effective potential with gauge dependence in the $R_\xi$ gauges together with 3-loop beta ... -
Ge-capped SiGe core optical fibers
(Journal article; Peer reviewed, 2019)CO2 laser processing offers the possibility to inscribe structures within glass-clad SiGe-core fibers by altering the spatial distribution of the Si and Ge. Spatial segregation of Ge to the end of a fiber is shown via ... -
Gelling kinetics and in situ mineralization of alginate hydrogels: A correlative spatiotemporal characterization toolbox.
(Journal article; Peer reviewed, 2016)Due to their large water content and structural similarities to the extracellular matrix, hydrogels are an attractive class of material in the tissue engineering field. Polymers capable of ionotropic gelation are of special ... -
Gender Differences in Norwegian Engineering Students’ Understanding of Newtonian Mechanics
(Peer reviewed; Journal article, 2020)An investigation of the gender gap in engineering students’ understanding of Newtonian physics has been done. The results indicate a noticeable gender gap, in addition to an effect due to differences in preparation, i.e. ... -
General boundary conditions for quasiclassical theory of superconductivity in the diffusive limit: Application to strongly spin-polarized systems
(Journal article; Peer reviewed, 2015)Boundary conditions in quasiclassical theory of superconductivity are of crucial importance for describing proximity effects in heterostructures between different materials. Although they have been derived for the ballistic ... -
