(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We introduce Project MegaSaura: the Magellan Evolution of Galaxies Spectroscopic and Ultraviolet Reference Atlas. MegaSaura comprises medium-resolution, rest-frame ultraviolet spectroscopy of N = 15 bright gravitationally ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We stack the rest-frame ultraviolet spectra of N = 14 highly magnified gravitationally lensed galaxies at redshifts $1.6\lt z\lt 3.6$. The resulting new composite spans $900\lt {\lambda }_{\mathrm{rest}}\lt 3000$ Å, with ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)There has been a common assumption among medievalists that the magical signs deriving from Eastern occult practices and known in Latin as caracteres first appeared in Western European manuscripts with the rise of “learned” ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Recently it has been argued that the Sveconorwegian orogeny in southwest Fennoscandia comprised a series of accretionary events between 1140 and 920 Ma, behind a long-lived, active continental margin characterized by ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Large Igneous Provinces (LIPs) whose magma plumbing systems intersect sedimentary basins are linked to upheavals of Earth’s carbon and sulfur cycles and thus climate and life history. However, the underlying mechanistic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Hydrides based on magnesium and intermetallic compounds provide a viable solution to the challenge of energy storage from renewable sources, thanks to their ability to absorb and desorb hydrogen in a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Magnesium is a divalent ion involved in a range of biochemical reactions and cellular functions. The metabolism and requirements for magnesium are still insufficiently understood. In the Nordic Nutrition Recommendations ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract When charged particles in periodic lattices are subjected to a constant electric field, they respond by oscillating. Here we demonstrate that the magnetic analogue of these Bloch oscillations are realised in a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (∼ 6000 km) and orientation mechanisms are unknown. Several attempts have been ...
-
(Chapter / Bokkapittel / SubmittedVersion, 2021)Palladium (Pd) is a scarce metal, which is able to catalyze a variety of important chemical reactions. In the bulk form, Pd is anomalous paramagnetic, but in the form of nanoparticles, it has been reported as ferromagnetic. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Ubiquitous in most superconducting materials and a common result of nanofabrication processes, weak links are known for their limiting effects on the transport of electric currents. Still, they are at the root of key ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Context: Umbral flashes (UF) and running penumbral waves (RPWs) in sunspot chromospheres leave a dramatic imprint in the intensity profile of the Ca II 8542 Å line. Recent studies have focussed on also explaining the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Analytical models are presented for currents along vertical magnetic field lines due to slow bulk electron motion in plasmas subject to a gravitational force. It is demonstrated that a general feature of this problem is a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Magneto-optical imaging of YBa2Cu3O7-δ films with high critical current density, synthesized by a cost-effective metal organic decomposition technique reveals inhomogeneous flux penetration in the specimens in the form of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Magneto-optical imaging of dendritic flux instability is reported for NbN films exposed to magnetic fields ramped at a fast rate (0.1–3.2 kT s−1 ). The results show that as the magnetic ramp rate increases, the temperature ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Thickness uniformity is regarded as an important parameter in designing thin film devices. However, some applications based on films with nonuniform thickness have recently emerged, such as gas sensors and optimized materials ...
-
(Chapter / Bokkapittel / SubmittedVersion, 2021)Being biological object, microtubules attract significant attention in physics, since it is believed that they are responsible for quantum processing of information in the brain. There were, however, no direct experiments ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The magnetic activity of the Sun directly impacts the Earth and human life. Likewise, other stars will have an impact on the habitability of planets orbiting these host stars. Although the magnetic field at the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract A pile of grains, even when at rest in a silo, can display fascinating properties. One of the most celebrated is the Janssen effect, named after the pioneering engineer who explained the pressure saturation at the ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)We present a numerical approach to magnetic optical rotation based on real-time time-dependent electronic-structure theory. Not relying on perturbation expansions in the magnetic-field strength, the formulation allows us ...
