The high-velocity cloud complex Galactic Center Negative as seen by EBHIS and GASS. I. Cloud catalog and global properties
ISM: clouds – Galaxy: halo
2011/10/10
Using Milky Way data of the new Effelsberg-Bonn HI Survey (EBHIS) and the Galactic All-Sky Survey (GASS), we present a revised picture of the high-velocity cloud (HVC) complex Galactic Center Negative...
Gas Gain Measurements from a Negative Ion TPC X-ray Polarimeter
Gas Gain Measurements Negative TPC X-ray Polarimeter
2011/10/9
Gas-based time projection chambers (TPCs) have been shown to be highly sensitive X-ray polarimeters having excellent quantum efficiency while at the same time achieving large modulation factors. To ob...
Properties of the negative effective magnetic pressure instability
magnetohydrodynamics (MHD) – instabilities – turbulence
2011/10/9
As was demonstrated in earlier studies, turbulence can result in a negative contribution to the effective mean magnetic pressure, which, in turn, can cause a large-scale instability. In this study, hy...
