On the injection of helicity by shearing motion of fluxes in relation to Flares and CMEs
activity flares magnetic fields Coronal Mass ejections magnetic polarity inversion line
2012/2/24
An investigation of helicity injection by photospheric shear motions is presented for two active regions, NOAA 11158 and 11166, using LOS magnetic field observations obtained from the Helioseismic and...
Joint downscale fluxes of energy and potential enstrophy in rotating stratified Boussinesq flows
Turbulent ows Strati ed ows Rotating ows
2011/10/14
We employ a coarse-graining approach to analyze nonlinear cascades in Boussinesq flows using high-resolution simulation data. We derive budgets which resolve the evolution of energy and potential enst...
Systematics in Aggregated Neutrino Fluxes and Flavor Ratios from Gamma-Ray Bursts
Systematics Aggregated Neutrino Fluxes Flavor Ratios Gamma-Ray Bursts
2011/10/20
Gamma-ray burst analyses at neutrino telescopes are typically based on diffuse or stacked (i.e., aggregated) neutrino fluxes, because the number of events expected from a single burst is small. The ag...
Measurement of the $ν_e$ and Total $^{8}$B Solar Neutrino Fluxes with the Sudbury Neutrino Observatory Phase-III Data Set
Measurement Total $^{8}$B Solar Neutrino Fluxes udbury Neutrino Observatory
2011/10/17
This paper details the solar neutrino analysis of the 385.17-day Phase-III data set acquired by the Sudbury Neutrino Observatory (SNO). An array of $^3$He proportional counters was installed in the he...
Gamma-Ray Constraints on Maximum Cosmogenic Neutrino Fluxes and UHECR Source Evolution Models
Gamma-Ray Constraints Cosmogenic Neutrino Fluxes Source Evolution Models
2011/9/29
The dip model assumes that the ultra-high energy cosmic rays (UHECRs) above 10$^{18}$ eV consist exclusively of protons and is consistent with the spectrum and composition measure by HiRes. Here we pr...
The observation of astrophysical neutrinos requires a detailed understanding of the atmospheric neutrino background. Since neutrinos are produced in meson decays together with a charged lepton, import...
p, He, and C to Fe cosmic-ray primary fluxes in diffusion models: Source and transport signatures on fluxes and ratios
Methods statistical – ISM cosmic rays
2010/11/10
Context. The source spectrum of cosmic rays is not well determined by diffusive shock acceleration models. The prop-agated fluxes of proton, helium, and heavier primary cosmic-ray species (up to Fe) a...
Energetic neutral atom fluxes from the heliosheath varying with the activity phase of the solar cycle
Energetic neutral atom fluxes solar cycle
2009/5/27
Energetic neutral atoms (ENA's) which are produced in the heliospheric interface can be used to remotely investigate this highly interesting, but poorly known region acting as buffer against the inter...
The TWINS-LAD mission：Observations of terrestrial Lyman-α fluxes
terrestrial Lyman-α fluxes line-of-sight Two Wide-angle Imaging Neutral-atom Spectrometers
2009/5/27
The TWINS project (Two Wide-angle Imaging Neutral-atom Spectrometers) is mainly devoted to measure high energy neutral atoms (ENAs) originating via charge exchange of protons with geocoronal hydrogen ...
