The Large-scale Bipolar Wind in the Galactic Center

During a 9-month campaign (1996–1997), the Midcourse Space Experiment (MSX) satellite mapped the Galactic Plane at mid-infrared wavelengths (4.3–21.3μm). The much greater spatial resolution and sensitivity of the MSX 8.3μm band compared to IRAS at 12μm has revealed diffuse emission not seen before. Here we report evidence for a spectacular limb-brightened, bipolar structure at the Galactic Cent...

Galactic Rotation and Large Scale Structures

On the basis of a recent cosmological model, the puzzle of galactic rotational velocities at their edges is explained without invoking dark matter. A rationale for the existence of structures like galaxies and superclusters is also obtained.

Large and small-scale structures of the local Galactic disc

An analytical model based on the maximum entropy approach is proposed to describe the eventual asymmetries of the velocity distribution, which are collected through its sample moments. If an extended set of moments is available, the current method provides a linear algorithm, associated with a Gramian system of equations, that leads to a fast and suitable estimation of the velocity distribution...

Scale Radio Structuers in the Galactic Center

Radio continuum observations of the galactic center region have revealed a number of vertical structures running across the galactic plane. Most of the vertical structures are reasonably attributed either to poloidal magnetic field or to energy release toward the halo. The relation of the continuum structures to the molecular gas rings and their vertical extension are also discussed. Some large...

First Results from Sparo: Evidence for Large-scale Toroidal Magnetic Fields in the Galactic Center

We have observed the linear polarization of 450 μm continuum emission from the Galactic center, using a new polarimetric detector system that is operated on a 2 m telescope at the South Pole. The resulting polarization map extends ∼ 170 pc along the Galactic plane and ∼ 30 pc in Galactic latitude, and thus covers a significant fraction of the central molecular zone. Our map shows that this regi...
