Massive compact halo object

Massive Compact Halo Objects (MACHOs)
MACHO is a collective term for objects that reside in the halo of a galaxy and which do not emit enough radiation to be detected from Earth. Examples include brown dwarfs.

Massive Compact Halo Object -- These are black holes, neutron stars and brown dwarfs, none of which are luminous and all of which are postulated to exist in the halos of galaxies. They are a form of dark matter.
Maclaurin Series ...

MACHO: Massive Compact Halo Object. Any object such as a white dwarf, neutron star, or black hole that could account for some or all of the dark matter in the halos of galaxies.

MACHO: MAssive Compact Halo Object, and also one of projects searching for MACHOs by looking for gravitational microlensing: the other projects are EROS and OGLE. A MACHO is an object with a mass from about 10 billion tons to solar masses.

MACHOs: Massive Compact Halo Objects; low-luminosity objects such as planets and brown dwarfs that contribute to the mass of the halo.

MACHO stands for Massive Compact Halo Object. MACHOs are objects that could account for some (or all) of the dark matter in the halos of galaxies, like white dwarfs, neutron stars, and black holes.

MACHOs (NASA Thesaurus) See massive compact halo objects. Maclaurin series (NASA SP-7, 1965) See Taylor theorem. macroscopic (NASA SP-7, 1965) Large enough to be visible to the naked eye or under low order of magnification.

having the physics people come up with the answers to an astronomical problem, so they came up with MACHOs (not because astronomers are tough and physicists are wimps, or perhaps that is the reason...), which stands for Massive Compact Halo Objects.

Neutrinos would be hot unless their rest mass is higher than experiment now indicates, and the often-hypothesized weakly interacting massive particles (WIMPs, as contrasted to MACHOS = massive compact halo objects) and other baryonic forms would be ...

MACHOs (Massive Compact Halo Objects) are Dark Matter candidates consisting of condensed objects such as black holes, neutron stars, white dwarfs, very faint stars, or non-luminous objects like planets.

These are Massive Compact Halo Objects and would include things like neutron stars, brown dwarfs, white dwarfs and the like that may lurk undetected in the haloes of galaxies.

Some believe that it may be normal objects such as cold gasses, dark galaxies, or massive compact halo objects (called MACHOs, they would include black holes and brown dwarfs).

Macho can refer to:*The property of being overtly masculinity, hence the Spanish word Machismo*Massive compact halo object , a general name for any kind of astronomical body that might explain the apparent presence of dark matter in galaxy halos..

MACHO- an acronym for "Massive Compact Halo Object" - supposed dark, massive objects surrounding our galaxy
Magnetosphere- the are around a planet in which its magnetic field is dominant ...

This can be in the form of Massive Compact Halo Objects (MACHOs) which may be too small to glow brightly (or other, more bizarre objects) or it can be heavy particles, or shadow matter, or primordial , or any of a number of other things.

At least part of the dark matter could be in some baryonic form such as massive compact halo objects (MACHOs), ...

* MACHOs or Massive Compact Halo Objects assumes that the dark matter consists of condensed objects such as black holes, neutron stars, white dwarfs, very faint stars, or non-luminous objects like planets.

Possibilities involving normal baryonic matter include brown dwarfs or perhaps small, dense chunks of heavy elements; such objects are known as massive compact halo objects, or "MACHOs".

Over the past decade, he had developed wonderful "visualizations" of recently discovered extrasolar planetary systems, protoplanetary disks, extragalactic worlds, and Massive Compact Halo Objects (MACHOS), which were admired internationally.

faced with the complete mystery of such an enormous fraction of the universe's constituent material, have proposed a number of unusual possibilities, from weakly interacting massive particles (WIMPs) such as neutrinos, to massive compact halo objects ...

However, there are a number of candidates, such as a stable supersymmetric particle, a weakly interacting massive particle, an axion, a massive compact halo object.

There is currently a search underway for such objects which go by the name of MAssive Compact Halo Objects (MACHO).
