Dynamo action in the cores of planets and stars gives rise to their magnetic fields. We explore spherical Couette flows in liquid sodium as a laboratory model of the Earth’s core. Below, we image various spatiotemporal magnetic-field modes present in spherical Couette flows. Our apparatus is comprised of two independently driven rotating spheres, radii 20 and 60 cm, with sodium filling the gap ...

[1] Correlations between geomagnetic-field and climate parameters have been suggested repeatedly, but possible links are controversially discussed. Here we test if weak (Earth-strength) magnetic fields can affect climatically relevant properties of seawater. We found the solubility of air in seawater to be by 15% lower under reduced magneticfield (20 mT) compared to normal field conditions (50 ...

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and leadlead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 1034 cm−2s−1 (1027 cm−2s−1). At the core of the CMS detector sits a high-magneticfield and large-bore superconducting sol...

We summarise the recent progress of a project to determine physical conditions in the jets of low-luminosity (FR I) radio galaxies. We model the jets as intrinsically symmetrical, relativistic, decelerating flows. By fitting to deep, high-resolution VLA images in total intensity and linear polarization, we have been able to derive for the first time the three-dimensional distributions of veloci...

We report on Australia Telescope Compact Array observations in the direction of the young high magneticfield pulsar J1119–6127. In the resulting images we identify a non-thermal radio shell of diameter 15, which we classify as a previously uncatalogued young supernova remnant, G292.2–0.5. This supernova remnant is positionally coincident with PSR J1119–6127, and we conclude that the two objects...

Lunar swirls are delicate light-coloured markings on the Moon’s surface. The lighter soil is unweathered, having been somehow shielded from the solar wind. Although lunar swirls are known to be associated with anomalous magnetic fields, their exact origin has remained mysterious — however, Ruth Bamford and colleagues have now tied together satellite data, laboratory experiments and a theoretica...

In this paper we study External A*, a variant of the internal A* algorithm that employs external memory. The approach applies to implicit, undirected, unweighted state space problem graphs with consistent estimates. The complexity of the External algorithm is almost linear in external sorting time and accumulates to O(sort(|E|) + scan(|V |)) I/Os, where V and E are the set of nodes and edges in...
