| Satire | HALO, n. Properly, a luminous ring encircling an astronomical body, but not infrequently confounded with "aureola," or "nimbus," a somewhat similar phenomenon worn as a head-dress by divinities and saints. The halo is a purely optical illusion, produced by moisture in the air, in the manner of a rainbow; but the aureola is conferred as a sign of superior sanctity, in the same way as a bishop's mitre, or the Pope's tiara. In the painting of the Nativity, by Szedgkin, a pious artist of Pesth, not only do the Virgin and the Child wear the nimbus, but an ass nibbling hay from the sacred manger is similarly decorated and, to his lasting honor be it said, appears to bear his unaccustomed dignity with a truly saintly grace.

| Physics | 1: The cold, dense plasma formed outside the last closed flux surface during a vertical displacement event. The large currents which flow through this plasma stop the displacement and transfer the force to the vacuum vessel. If care is not taken in design, the halo currents can be large enough to threaten the structural integrity of the vacuum vessel or in-vessel components. Whereas the center of a tokamak plasma is too hot for material probes to survive, probes (such as magnetic-field coils) can sometimes be placed in the halo, and can measure things such as the halo current.

Common Expressions: halo
| Expressions | Definition | ||
| Cuspy halo problem | The cuspy halo problem arises from cosmological simulations that seem to indicate cold dark matter would form cuspy distributions—that is, increasing sharply to a high value at a central point—in the most dense areas of the universe. This would imply that the center of our galaxy, for example, should exhibit a higher dark-matter density than other areas. However, it seems rather that the centers of these galaxies likely have no cusp in the dark-matter distribution at all. (references) | ||
| Easter eggs in Halo | The Meg Easter egg ("Megg") was a private gift from Jaime Griesemer (Designer on Halo, Lead Designer on Halo 2) for his significant other, Meg Sagi (a.k.a. Pallor). It is located in a normally locked room near the bridge of the Pillar of Autumn. The Megg can be seen by completing a sequence of events, or "triggers," that are not included in the normal sequence of the game. It was a personal gift and therefore not intended to be seen by the normal player, but its discovery sparked a massive hunt to find how to unlock it. According to Meg, the gift incorporated many elements of the game that she enjoyed - "senseless carnage, insane tasks, blood, bullets, dying, and an old fashioned image." There is no Megg in the Halo port for PC, but you can still get to the secret room by fulfilling the same triggers. (references) | ||

| Massive compact halo object | Massive compact halo object, or MACHO, is a general name for any kind of astronomical body that might explain the apparent presence of dark matter in galaxy halos. A MACHO is a small chunk of normal baryonic matter, which emits little or no radiation and drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. MACHOs may sometimes be black holes or neutron stars as well as brown dwarfs or unassociated planets. White dwarfs and very faint red dwarfs have also been proposed as candidate MACHOs. (references) | ||

| Halo current | Physics | 1: Current which flows outside the confined plasma region, in the scrape-off layer. During a VDE, the plasma makes contact with a limiter and starts to be scraped off, causing a fraction of the plasma current to flow along the field lines. The current path can intercept a material surface, where the current will take the path of least resistance, causing intense heating and deformation of the material. The effects of halo currents may not be axisymmetric, and can cause great damage. They are a potential concern for Next Step devices. (references) | |
