THE SHADOW CAST. “Observations of nearby spiral galaxies have revealed a regular large scale pattern that follows the spiral arms. However these observations are 2D projections of a 3D field, of which the exact topology remains a mystery.” https://lnkd.in/gTA_aVgT View in LinkedIn

SAVANT SYNDROME. “Daniel first became famous when he recited from memory Pi to 22,514 decimal places. Numbers, according to Daniel, are special to him. He has a rare form of synesthesia and sees each integer up to 10,000 as having their own unique shapes, color, texture and feel. He can "see" the result of a math calculation, and he can "sense" whether a number is prime. Daniel speaks 11 languages, one of which is Icelandic.” https://lnkd.in/gfQFZ2jD View in LinkedIn

SO ENDS this first weekend on the fascinating theme of magnetism, which stretches from within the atom to across vast galaxies. This all-pervasive ether is the liquid that the cosmos is bathed in, the primal sea, perhaps even the maternal fluid of matter. It seems to have unlimited reach and influence, but our understanding of it is at best rudimentary. View in LinkedIn

SURROGATE MARKER. “Most of what we know about galactic magnetic fields comes through the detection of radio waves.” https://lnkd.in/gA4b9wZV View in LinkedIn

KEY TO THE UNIVERSE. “Magnetism contributes to every astrophysical process on every scale and its study offers considerable opportunity for transformational understanding.” https://lnkd.in/gTA_aVgT View in LinkedIn

BLACK BOX. “Theory tells us the magnetic fields pervade all of this intergalactic space, but as yet there have been no measurements of intergalactic magnetic fields. The origin of cosmic fields and their evolution and role in structure formation is unknown.” https://lnkd.in/gTA_aVgT View in LinkedIn

STRUCTURED UNIVERSE. “We know that on the largest scales there is structure to the Universe: voids, filaments, and clusters (e.g. the cosmic web).” https://lnkd.in/gTA_aVgT View in LinkedIn

“MAGNETIC FIELDS in AGN are observed from pc scales to Mpc scales, e.g. from the non-thermal filaments in the Galactic centre, VLBI polarimetry of radio galaxy cores, to polarization of jets, and radio lobes. They affect the accretion disk, jet collimation and particle acceleration, and contribute significantly to the pressure inside radio lobes.” (AGN = Active Galactic Nuclei). https://lnkd.in/gTA_aVgT View in LinkedIn

JETS OF IONS. “Active Galactic Nuclei, powered by accretion on a supermassive black hole, eject relativistic jets that interact with the interstellar and intergalactic medium on sub-pc to Mpc scales.” https://lnkd.in/gTA_aVgT View in LinkedIn

ORIGINS. “Acceleration to these extreme energies could be due to transients such as massive supernovae or compact object mergers, active-galactic nuclei, or galaxy clusters, though the exact mechanism is unclear.” https://lnkd.in/gTA_aVgT View in LinkedIn
