Modelling anomalous cosmic ray oxygen in the heliosheath
(EDP Sciences, 2010)
This paper discusses a numerical modulation model to describe anomalous cosmic ray acceleration and transport in the heliosheath, the portion of the heliosphere between the termination shock and the heliopause. The model ...
Long-term neutron monitor observations and the 2009 cosmic ray maximum
(American Geophysical Union, 2010)
The solar minimum of 2009 was characterized by a prolonged increase toward the maximum cosmic ray intensity, which was higher than it was during the maxima of 22 and 44 years ago. In the previous two so-called qA <0 (solar ...
A calibration neutron monitor: statistical accuracy and environmental sensitivity
(Elsevier, 2010)
This paper is a follow-on of that of Krüger et al. [Krüger, H., Moraal, H., Bieber, J.W., Clem, J.M., Evenson, P.A., Pyle, K.R., Duldig, M.L., Humble, J.E. A calibration neutron monitor: energy response and instrumental ...
The dynamic heliosphere, solar activity, and cosmic rays
(Elsevier, 2010)
This brief review addresses the relation between solar activity, cosmic ray variations and the dynamics of the heliosphere. The global features of the heliosphere influence what happens inside its boundaries on a variety ...
The heliospheric transport and modulation of multiple charged anomalous oxygen revisited
(EDP Sciences, 2010)
Context. Since the crossings of the solar wind termination shock by the Voyager 1 and 2 spacecraft, much speculation has surrounded the acceleration mechanism and region where the anomalous cosmic ray component is accelerated. ...
The heliospheric modulation of cosmic rays: effects of a latitude dependent solar wind termination shock
(Elsevier, 2010)
Observations made with the two Voyager spacecraft confirmed that the solar wind decelerates to form the heliospheric termination shock and that it has begun its merger with the local interstellar medium. The compression ...
Observations of the Large Magellanic Cloud with Fermi
(EDP Sciences, 2010)
Context. The Large Magellanic Cloud (LMC) is to date the only normal external galaxy that has been detected in high-energy gamma rays. Highenergy
gamma rays trace particle acceleration processes and gamma-ray observations ...
