ψ (2S) Suppression in Pb-Pb Collisions at the LHC
(Journal article; Peer reviewed, 2024)The production of the 𝜓(2𝑆) charmonium state was measured with ALICE in Pb-Pb collisions at √𝑠NN =5.02 TeV, in the dimuon decay channel. A significant signal was observed for the first time at LHC energies down to ... -
The variability patterns of the TeV blazar PG 1553 + 113 from a decade of MAGIC and multiband observations
(Journal article; Peer reviewed, 2024)PG 1553 + 113 is one of the few blazars with a convincing quasi-periodic emission in the gamma-ray band. The source is also a very high energy (VHE; >100 GeV) gamma-ray emitter. To better understand its properties and ... -
J/psi production at midrapidity in proton-proton collisions at √s = 13 TeV with ALICE
(Doctoral thesis, 2025-03-17)Samspillet mellom det perturbative og ikke-perturbative regimet gjør charmonium produksjon til en viktig testarena for å utvide forståelsen av den sterke vekselvirkningen. Til tross for pågående innsats gjenstår det å ... -
Critical thinking in the making: students’ critical thinking practices in a multifaceted SSI project
(Journal article; Peer reviewed, 2024)Students’ critical thinking is often researched using quantitative tests designed to measure critical thinking. In contrast, this study qualitatively analyses group and whole-class dialogues in an interdisciplinary SSI ... -
Does high-latitude ionospheric electrodynamics exhibit hemispheric mirror symmetry?
(Journal article; Peer reviewed, 2024)Ionospheric electrodynamics is a problem of mechanical stress balance mediated by electromagnetic forces. Joule heating (the total rate of frictional heating of thermospheric gases and ionospheric plasma) and ionospheric ... -
Volumetric Reconstruction of Ionospheric Electric Currents From Tri-Static Incoherent Scatter Radar Measurements
(Journal article; Peer reviewed, 2024)We present a new technique for the upcoming tri-static incoherent scatter radar system EISCAT 3D (E3D) to perform a volumetric reconstruction of the 3D ionospheric electric current density vector field, focusing on the ... -
Initial stages of water absorption on CeO2 surfaces at very low temperatures for understanding anti-icing coatings
(Journal article; Peer reviewed, 2024)Anti-icing coatings are intended to prevent ice formation on surfaces, minimising the risk of surface-related damage and also reducing ice-related hazards in society. We demonstrate the usefulness of x-ray photoelectron ... -
Performance of the electromagnetic and hadronic prototype segments of the ALICE Forward Calorimeter
(Journal article; Peer reviewed, 2024)We present the performance of a full-length prototype of the ALICE Forward Calorimeter (FoCal). The detector is composed of a silicon-tungsten electromagnetic sampling calorimeter with longitudinal and transverse segmentation ... -
Exploring CP violation in H→τ+τ-γ
(Journal article; Peer reviewed, 2024)We propose a method of measuring the CP-odd part of the Yukawa interaction of Higgs boson and τ leptons by observing the forward–backward asymmetry in the decay H → τ + τ − γ . The source of such asymmetry is the inter- ... -
Induced carbonate dissolution: Impact of brine chemistry in CO2 foam
(Journal article; Peer reviewed, 2024)Foam CO2might be considered an efficient alternative to reduce gas mobility and produce favorable mobility ratios. It offers significant advantages, particularly in heterogeneous or fractured reservoirs due to its ability ... -
Performance and first measurements of the MAGIC stellar intensity interferometer
(Journal article; Peer reviewed, 2024)In recent years, a new generation of optical intensity interferometers has emerged, leveraging the existing infrastructure of Imaging Atmospheric Cherenkov Telescopes (IACTs). The MAGIC telescopes host the MAGIC-SII system ... -
Machine learning classification of sphalerons and black holes at the LHC
(Journal article; Peer reviewed, 2024)In models with large extra dimensions, “miniature” black holes (BHs) might be produced in high-energy proton–proton collisions at the Large Hadron Collider (LHC). In the semi-classical regime, those BHs thermally decay, ... -
The Growth and Decay of Intense GNSS Amplitude and Phase Scintillation During Non‐Storm Conditions
(Journal article; Peer reviewed, 2024)A multi‐instrument study is conducted at the dayside polar ionosphere to investigate the spatio‐ temporal evolution of scintillation in Global Navigation Satellite System (GNSS) signals during non‐storm conditions. Bursts ... -
Experimental study of a direct absorption solar collector with stationary nanofluid
(Journal article; Peer reviewed, 2024)In this study, an experimental assessment of the performance of carbon black nanofluids in a direct absorption solar collector was conducted. Unlike traditional direct absorption solar collectors, the laboratory setup in ... -
Atomic diffraction by nanoholes in hexagonal boron nitride
(Journal article; Peer reviewed, 2024)Fabricating patterned nanostructures with matter waves can help to realise new nanophotonic devices. However, due to dispersion effects, designing patterns with nanoscale features is challenging. Here, we consider the ... -
Impact of microbial biofilms on subsurface energy systems – from oil and gas to renewable energy
(Chapter, 2024)Microbial biofilms play a crucial role in subsurface energy systems, such as hydrocarbon reservoirs and underground CO2 and hydrogen (H2) storage. Biofilm accumulation in the pore space can result in clogging, which can ... -
