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...
A High Galactic Latitude HI 21cm-line Absorption Survey using the GMRT：II. Results and Interpretation
clouds kinematics and dynamics radio lines
2009/5/14
We have carried out a sensitive high-latitude (|b| > 15◦)
HI 21 cm-line absorption survey towards 102 sources using the GMRT.
With a 3σ detection limit in optical depth of ∼0.01, this is...
A High Galactic Latitude HI 21cm-line Absorption Survey using the GMRT：I. Observations and Spectra
clouds kinematics and dynamics radio lines
2009/5/14
We have used the Giant Meterwave Radio Telescope (GMRT)
to measure the Galactic HI 21-cm line absorption towards 102 extragalactic
radio continuum sources, located at high (|b| > 15◦) Galactic...
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...
A COMPARSION OF METAL AD LY-&ALPHA：ABSORPTION IN GALACTIC HALOES
galactic astrophysics observational cosmology GALACTIC HALOES
2009/3/26
The metallicity structure of galactic haloes is one of the major
unknowns in modern galactic astrophysics and observational cosmology. Hereby we
outline a very simple method for obtaining at least a...
OBSERVATIONAL DATA ON GALACTIC SUPERNOVA REMNANTS：I. THE SUPERNOVA REMNANTS WITHIN l = 0° - 90°
Catalogs–ISM supernova remnants–Stars neutron
2009/3/11
We have collected all the available data on Galactic supernova
remnants given in the literature. The data on Galactic supernova remnants located
in the Galactic longitude interval l=0◦–90ϊ...
OBSERVATIONAL DATA ON GALACTIC SUPERNOVA REMNANTS: III. THE SUPERNOVA REMNANTS WITHIN l = 270° - 360
Catalogs-ISM supernova remnants-Stars neutron
2009/3/5
We have collected all the available data of Galactic supernova rem-
nants given in the literature. The data of Galactic supernova remnants located in
the Galactic longitude interval l=270{360 in a...
GALACTIC SUBSYSTEMS ON THE BASIS OF CUMULATIVE DISTRIBUTION OF SPACE VELOCITIES
Galaxy kinematics and dynamics-structure-solar neighbourhood
2009/1/15
A sample containing 4 614 stars with available space velocities and
high-quality kinematical data from the Arihip Catalogue is formed. For the purpose
of distinguishing galactic subsystems the cumul...
