Electrojet Estimates From Mesospheric Magnetic Field Measurements
(Journal article; Peer reviewed, 2021)The auroral electrojet is traditionally measured remotely with magnetometers on ground or in low Earth orbit (LEO). The sparse distribution of measurements, combined with a vertical distance of some 100 km to ground and ... -
Electron Acceleration and Thermalization at Magnetotail Separatrices
(Journal article; Peer reviewed, 2020)In this study we use the Magnetospheric Multiscale mission to investigate the electron acceleration and thermalization occurring along the magnetic reconnection separatrices in the magnetotail. We find that initially cold ... -
Electron and photon energy calibration with the ATLAS detector using 2015–2016 LHC proton-proton collision data
(Peer reviewed; Journal article, 2019)This paper presents the electron and photon energy calibration obtained with the ATLAS detector using about 36 fb−1 of LHC proton-proton collision data recorded at √ s = 13 TeV in 2015 and 2016. The different calibration ... -
Electron and photon energy calibration with the ATLAS detector using LHC Run 1 data
(Peer reviewed; Journal article, 2014-10-01)This paper presents the electron and photon energy calibration achieved with the ATLAS detector using about 25 fb −1 of LHC proton–proton collision data taken at centre-of-mass energies of s√=7 and 8 TeV. The reconstruction ... -
Electron and photon performance measurements with the ATLAS detector using the 2015-2017 LHC proton-proton collision data
(Journal article; Peer reviewed, 2019)This paper describes the reconstruction of electrons and photons with the ATLAS detector, employed for measurements and searches exploiting the complete LHC Run 2 dataset. An improved energy clustering algorithm is introduced, ... -
Electron Behavior Around the Onset of Magnetic Reconnection
(Journal article; Peer reviewed, 2022)We investigate the onset of magnetic reconnection, utilizing a fully kinetic Particle-In-Cell (PIC) simulation. Characteristic features of the electron phase-space distributions immediately before reconnection onset are ... -
Electron Bernstein waves driven by electron crescents near the electron diffusion region
(Journal article; Peer reviewed, 2020)The Magnetospheric Multiscale (MMS) spacecraft encounter an electron diffusion region (EDR) of asymmetric magnetic reconnection at Earth’s magnetopause. The EDR is characterized by agyrotropic electron velocity distributions ... -
Electron Density Depletion Region Observed in the Polar Cap Ionosphere
(Journal article; Peer reviewed, 2021)This paper presents and discusses electron density depletion regions observed with the incoherent scatter EISCAT Svalbard Radar (ESR) located at 75.43°N geomagnetic latitude. The data include several decades of measurements, ... -
Electron Heating by Debye-Scale Turbulence in Guide-Field Reconnection
(Journal article; Peer reviewed, 2020)We report electrostatic Debye-scale turbulence developing within the diffusion region of asymmetric magnetopause reconnection with a moderate guide field using observations by the Magnetospheric Multiscale mission. We show ... -
Electron inflow velocities and reconnection rates at earth's magnetopause and magnetosheath
(Journal article; Peer reviewed, 2020)Electron inflow and outflow velocities during magnetic reconnection at and near the dayside magnetopause are measured using satellites from NASA's Magnetospheric Multiscale (MMS) mission. A case study is examined in detail, ... -
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 ... -
Electronic properties of chlorine, methyl, and chloromethyl as substituents to the ethylene group-viewed from the core of carbon
(Peer reviewed; Journal article, 2015-08-17)“Substituent effects” is an important and useful concept in organic chemistry. Although there are many approaches to parametrizing the electronic and steric effects of substituents, the physical basis for the parameters ... -
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 ... -

Element composition of particulate matter in the North-West Barents Sea
(Master thesis, 2022-08-10)At the dawn of the 21st century, the Arctic Ocean ecosystem is at great risk due to rapid climatic change. The ice edge retreat observed in the Barents Sea and other sub-Arctic areas is so substantial that has led researchers ... -
Elemental composition of illicia and otoliths and their potential application to age validation in white anglerfish (Lophius piscatorius linnaeus, 1758)
(Journal article; Peer reviewed, 2021)The incorporation of trace elements into the calcified structures of fish can vary seasonally. Interpretation of these seasonal signals can provide information about fish age. This approach offers great promise for objectively ... -
