"There are not enough machos in the galactic halo, " said Dr . Eric Aubourg of EROS . " It looks like everybody agrees on this ."
32.
For his innovative development and utilization of instrumentation to attack fundamental issues in physics and astronomy, including the discovery of baryonic dark matter in the galactic halo.
33.
The image hints at the power of the VST and OmegaCAM for surveying the extragalactic Universe and for mapping the low brightness objects of the galactic halo.
34.
The cluster appears to be producing a thermal chimney of ionized gas, caused by the interaction of the gas from the galactic disk with the galactic halo.
35.
These include colliding galaxy systems, accretion �ow shocks to clusters of galaxies, and more exotic processes from the superheavy particles trapped in the galactic halo, or topological defects.
36.
Inspired by this proposal, Jan Oort, of Leiden University, Netherlands, proposed that cold gas clouds might be found in the galactic halo, far away from the galactic plane.
37.
The cluster is following a retrograde orbit through the inner galactic halo, suggesting that it was acquired from a satellite galaxy rather than forming within the Milky Way.
38.
:Combining SEGUE-1 and 2 reveals the complex kinematic and chemical substructure of the Galactic halo and disks, providing essential clues to the assembly and enrichment history of the Galaxy.
39.
APM 08279 + 5255 was initially identified as a quasar in 1998 during an Automatic Plate Measuring Facility ( APM ) survey to find carbon stars in the galactic halo.
40.
One approach to solving the cusp-core problem in galactic halos is to consider models that modify the nature of dark matter; theorists have considered meta-cold dark matter, among other possibilities.
