But how could the researchers be sure that the salmon were using both the magnetic field intensity and inclination in their mental maps? The scientists tested this by exposing them to mixed-up ...

The study, published in Nature Communications, uses a method called synchrotron intensity gradient (SIG) to map magnetic fields in clusters, especially during galaxy mergers. This method provides ...

They made the maps using a technique he devised called synchrotron intensity gradient (SIG) mapping, which relies on radio observations to work out which way a cluster’s magnetic field points at a ...

It also combines a Stokes polarimeter, which images other spectral information such as coronal line intensity ... dimensional map of the strength and direction of the coronal magnetic field.

This region, known as the South Atlantic Anomaly (SAA), is marked by significantly reduced magnetic intensity, allowing high-energy solar particles to approach closer to Earth than usual.

However, the exact nature of this 'map' has been the subject of ongoing ... geographic location while keeping the total magnetic intensity unchanged. Despite this 'virtual displacement', the ...
