All-sky dynamical response of the Galactic halo to the Large Magellanic Cloud
Nature, 2021Gravitational interactions between the Large Magellanic Cloud (LMC) and the stellar and dark matter halo of the Milky Way are expected to give rise to disequilibrium phenomena in the outer Milky Way1–7. A local wake is predicted to trail the orbit of the

The Structure of the Galactic Halo [PDF]
Chinese Journal of Astronomy and Astrophysics, 2008 We used the star counts in 21 BATC fields obtained with the National Astronomical Observatories (NAOC) 60/90 cm Schmidt Telescope to study the structure of the Galactic halo. Adopting a de Vaucouleurs r1/4 law halo, we found that the halo is somewhat flatter (c/a~0.4) towards the Galactic center than in the anticentre and antirotation direction ( 0.4 ...

Is there dust in galactic haloes?
Nature, 1987The ubiquitous presence of dust within the disks of spiral galaxies is well established. Dust is present in large quantities over enormous extents in the Universe; for example, Burton1 concludes that, in our Galaxy, dust is distributed very similarly to the H I distribution, with an exponential radius in the plane of 8 kpc and an exponential scale ...

The variety of observational data suggest that the Galactic halo contains beside non-baryonic matter a noticeable fraction of cold baryonic matter.

The relationship between the Galactic halo and bulge is discussed, with reference to early results from a survey for K giants in a field 2 kpc from the Galactic center and Zinn's (1992) data on globular-cluster kinematics. The data are currently too meager to decide whether the inner halo shades gradually into the bulge, although there are some ...

AbstractThe interstellar medium in galactic halos is described as a consequence of feedback mechanisms from processes related to star-formation in the disk. The presence of gas in galactic halos is also expected due to accretion of gas from the circumgalactic environment.

Gravitational microlensing by the galactic halo
, 1986A simple model of microlensing by massive objects that might be present in the halo of the Galaxy is presented. It is shown that in any nearby galaxy one star out of a million is strongly microlensed by a dark object located in the Galactic halo, if the ...

Annual Review of Astronomy and Astrophysics, 1982
The evidence that gas exists in the halo of the Galaxy is examined. The likely properties of halo gas intervening between QSOs and the Galaxy are extracted from observations of the galactic halo. The available data discussed include 21-cm observations, optical absorption lines, ultraviolet lines, and X-ray observations.
