UNDERLYING FABRIC. “The search for magnetic fields in the intergalactic medium (IGM) is of fundamental importance for cosmology.” https://lnkd.in/gA4b9wZV View in LinkedIn

NO EMPTY SPACE. “All of “empty” space in the Universe may be magnetized. Its role as the likely seed field for galaxies and clusters and its possible relation to structure formation in the early Universe, places considerable importance on its discovery.” https://lnkd.in/gA4b9wZV View in LinkedIn

TIDAL WAVES. “Structure formation led to strong intergalactic shocks.” https://lnkd.in/gA4b9wZV View in LinkedIn

THE GYRES. “Radio observations of polarized synchrotron emission showed that the large-scale field structures in almost all nearby galaxies are spiral with pitch angles similar to those of the optical spiral arms.” https://lnkd.in/gA4b9wZV View in LinkedIn

SPIRAL DYNAMOS. “Spiral fields were also detected in galaxies without optical spiral structure and in circumnuclear gas rings. This indicates the action of dynamos in rotating galaxies, where the Coriolis force organizes turbulent gas motions, amplifying a weak seed field and generating coherent field structures.” https://lnkd.in/gA4b9wZV View in LinkedIn

THE UNKNOWN. “However, the physics of galactic dynamos is far from being understood.” https://lnkd.in/gA4b9wZV View in LinkedIn

UNIMAGINABLE SCALE. “Active galactic nuclei are powered by supermassive black holes that accrete matter and are capable of forming pairs of relativistic jets that can extend up to distances far larger than the size of the host galaxy.” https://lnkd.in/ebzBnWGP View in LinkedIn

CORE MAGNETISM. “The fact that jets in AGN are formed from magnetic systems, and that the magnetic field participating in their formation is partially dragged all along the jets, make polarization observations of their synchrotron emission a powerful tool to test magneto-hydrodynamic and emission models.” (AGN = Active galactic nuclei). https://lnkd.in/ebzBnWGP View in LinkedIn

IMAGES of cosmic magnetic fields. “Most of the visible matter in the Universe is ionized, so that cosmic magnetic fields are quite easy to generate and, due to the lack of magnetic monopoles, hard to destroy. Magnetic fields need illumination by cosmic rays, gas or dust to be detectable. Large regions in the Universe may be permeated by “dark” magnetic fields.” https://lnkd.in/eRjhYGXz View in LinkedIn

ELECTRICAL STRUCTURES. “The functional properties of materials and devices are critically determined by the electromagnetic field structures formed inside them, especially at nanointerface and surface regions, because such structures are strongly associated with the dynamics of electrons, holes and ions.” https://lnkd.in/eRAK9d4N View in LinkedIn
