Long-Term multi-wavelength study of 1ES 0647+250
(Journal article; Peer reviewed, 2023)Context. The BL Lac object 1ES 0647+250 is one of the few distant γ-ray emitting blazars detected at very high energies (VHEs; ≳100 GeV) during a non-flaring state. It was detected with the MAGIC telescopes during a period ... -
Longitudinal and azimuthal evolution of two-particle transverse momentum correlations in Pb–Pb collisions at √sNN=2.76 TeV
(Journal article; Peer reviewed, 2020)This paper presents the first measurements of the charge independent (CI) and charge dependent (CD) two-particle transverse momentum correlators G^CI_2 and G^CD_2 in Pb–Pb collisions at √sNN = 2.76 TeV by the ALICE ... -
Longitudinal asymmetry and its effect on pseudorapidity distributions in Pb–Pb collisions at √sNN = 2.76 TeV
(Peer reviewed; Journal article, 2018-03-22)First results on the longitudinal asymmetry and its effect on the pseudorapidity distributions in Pb–Pb collisions at √sNN = 2.76 TeV at the Large Hadron Collider are obtained with the ALICE detector. The longitudinal ... -
Longitudinal Flow Decorrelations in Xe+Xe Collisions at √sNN =5.44 TeV with the ATLAS Detector
(Journal article; Peer reviewed, 2021)The first measurement of longitudinal decorrelations of harmonic flow amplitudes vn for n=2–4 in Xe+Xe collisions at √sNN=5.44 TeV is obtained using 3 μb−1 of data with the ATLAS detector at the LHC. The decorrelation ... -
Low Power Giga Bit Transceiver (lpGBT) Test-Suite
(Master thesis, 2023-12-20)The ALICE detector, one of the key instruments at CERN's LHC, is dedicated to capturing and measuring the properties of particles generated in high-energy particle collisions. To enhance its capabilities for studying these ... -
Low Salinity Waterflood in Combination with Surfactant/Polymer: Effect of Brine Composition
(Master thesis, 2014-06-02)The effect of low salinity water (LSW) on enhanced oil recovery has been known for decades. Although much research is done on the topic, a general agreement of the prevailing mechanism for the low salinity effect has still ... -
Low Salinity Waterflood in Combination with Surfactant/Polymer; Effect of Surfactant Slug Size
(Master thesis, 2014-06-02)In last years, there has been a growing interest in the effect of reducing salinity of injected water in oil recovery. Many studies have showed that low salinity waterflooding is a promising method that can lead to a ... -
Low Salinity Waterflood in Combination with Surfactant/Polymer; Effects of Kinetics and Brine Composition
(Master thesis, 2014-06-01)Improving the oil recovery beyond what is possible by conventional methods is a topic of great interest, and the potential oil recovery for a field can be improved if unconventional methods are implemented. Reducing the ... -
Low Salinity Waterflooding in Combination with Surfactant/Polymer. A Field Scale Simulation Study of Hybrid EOR
(Master thesis, 2018-06-27)It is projected that 77% of energy consumption will originate from fossil fuels in 2040, indicating a continuous demand for crude oil [1]. Nevertheless, more than half of the hydrocarbons produced at present originate from ... -
Low-energy electron ionization mass spectrometer for efficient detection of low mass species
(Journal article; Peer reviewed, 2021)The design of a high-efficiency mass spectrometer is described, aimed at residual gas detection of low mass species using low-energy electron impact, with particular applications in helium atom microscopy and atomic or ... -
Low-energy probes of no-scale SU(5) super-GUTs
(Journal article; Peer reviewed, 2021)We explore the possible values of the \(\mu \rightarrow e \gamma \) branching ratio, \(\text {BR}(\mu \rightarrow e\gamma )\), and the electron dipole moment (eEDM), \(d_e\), in no-scale SU(5) super-GUT models with the ... -
Low-energy surface vibration measurements on the alpha-quartz (0001) surface
(Master thesis, 2011)Despite the enormous range of usages, only little is known about the dynamic and structural properties of quartz (SiO2) surfaces on the atomic scale. The main reason for this is probably that quartz is an insulator, with ... -
Lower-Hybrid Drift Waves Driving Electron Nongyrotropic Heating and Vortical Flows in a Magnetic Reconnection Layer
(Journal article; Peer reviewed, 2020)We report measurements of lower-hybrid drift waves driving electron heating and vortical flows in an electron-scale reconnection layer under a guide field. Electrons accelerated by the electrostatic potential of the waves ... -
Lower-thermosphere–ionosphere (LTI) quantities: current status of measuring techniques and models
(Journal article; Peer reviewed, 2021)The lower-thermosphere–ionosphere (LTI) system consists of the upper atmosphere and the lower part of the ionosphere and as such comprises a complex system coupled to both the atmosphere below and space above. The atmospheric ... -
