Galactic Fireworks Illuminate Monster Hydrogen Blob
Galactic Fireworks Monster Hydrogen Blob
2016/9/29
An international team of researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes has discovered the power source illuminating a so-called Lyman-alpha Blob – a ra...
Constraining Galactic Magnetic Field Models with Starlight Polarimetry
Constraining Galactic Magnetic Field Models Starlight
2011/10/8
This paper provides testable predictions about starlight polarizations to constrain the geometry of the Galactic magnetic field, in particular the nature of the poloidal component. Galactic dynamo sim...
Interaction between dark matter sub-halos & galactic gaseous disk
Interaction sub-halos galactic gaseous disk
2011/10/8
We investigate the idea that the interaction of Dark Matter (DM) sub-halos with the gaseous disk of galaxies can be the origin for the observed holes and shells found in their neutral hydrogen (HI) di...

Forbush decrease of the galactic cosmic ray intensity：experimental study and theoretical modeling
cosmic ray intensity theoretical modeling
2009/5/27
We study the temporal changes of the power law rigidity spectrum of the Forbush decrease (Fd) of the galactic cosmic ray (GCR) intensity. We show that the power law rigidity spectrum of Fd for the pe...
27-day variations of the galactic cosmic ray intensity and anisotropy
cosmic ray intensity 27-day variations
2009/5/27
We study the 27-day variations of the galactic cosmic ray (GCR) intensity and three dimensional (3-D) anisotropy in different polarity periods of the solar magnetic cycle. We found that the larger am...
Some Doubts on the Validity of the Foreground Galactic Contribution
Cosmic microwave background—ISM clouds—dust extinction—ISM structure
2009/5/12
The Galactic foreground contamination inCMBRanisotropies,
especially from the dust component, is not easily separable from the cosmological
or extragalactic component. In this paper, some doubts wi...
