Three Types Of Extreme-Energy Space Particles May Have Unified Origin（图）
Three Types Extreme-Energy Space Particles Unified Origin
2018/2/1
One of the biggest mysteries in astroparticle physics has been the origins of ultrahigh-energy cosmic rays, very high-energy neutrinos, and high-energy gamma rays. Now, a new theoretical model reveals...
If you thought Luke Skywalker's home planet, Tatooine, was a strange world with its two suns in the sky, imagine this: a planet where you'd either experience constant daylight or enjoy triple sunrises...
Multi-moment advection scheme in three dimension for Vlasov simulations of magnetized plasma
Advection equation Conservative form Multi-moment Vlasov simulations Magnetized plasma
2012/2/21
We present an extension of the multi-moment advection scheme (Minoshima et al., 2011, J. Comput. Phys.) to the three-dimensional case, for full electromagnetic Vlasov simulations of magnetized plasma....
Three regions of excessive flux of cosmic rays with energies of the order of PeV are found in the experimental data of the EAS MSU array at a confidence level greater than 4\sigma. For two of them, th...
Photometric SN Ia Candidates from the Three-Year SDSS-II SN Survey Data
Photometric Candidates Three-Year SDSS-II SN Survey Data
2011/10/21
We analyze the three-year SDSS-II Superernova (SN) Survey data and identify a sample of 1070 photometric SN Ia candidates based on their multi-band light curve data. This sample consists of SN candida...
A critical analysis of three near-infrared photometric methods of estimating distances to cataclysmic variables
Stars: novae cataclysmic variables Stars:distances parallaxes Stars:statistics
2011/10/13
A critical analysis of three methods of estimating distances to cataclysmic variables (CVs) is performed. These methods, by Ak et al., Beuermann, and Knigge, all use near-infrared (JHK or Ks) magnitud...
Spectroscopic Confirmation of Three z-Dropout Galaxies at z = 6.844 - 7.213: Lyman Alpha Demography of z ~ 7 Galaxies
Spectroscopic Confirmation z-Dropout Galaxies Lyman Alpha Demography z ~ 7 Galaxies
2011/10/10
We present the results of our ultra-deep Keck/DEIMOS spectroscopy of z-dropout galaxies in the SDF and GOODS-N. For 3 out of 11 objects, we detect an emission line at ~ 1um with a signal-to-noise rati...
The secular approximation for the evolution of hierarchical triple configurations has proven to be very useful in many astrophysical contexts, from planetary to triple-star systems. In this approximat...
The Optical Gravitational Lensing Experiment. Dwarf Novae in the OGLE Data. I. Three New Dwarf Novae: One in the Period Gap and Two Longer Period Objects
novae, cataclysmic variables – binaries: close – surveys
2011/10/8
We report serendipitous discovery of three new dwarf novae which eruptions in 2010 were observed by the ongoing microlensing survey OGLE-IV. All three objects are located in the Galactic bulge fields ...
Three-Dimensional Reconstruction of an Erupting Filament with SDO and STEREO Observations
Three-Dimensional Reconstruction Erupting Filament Observations
2011/9/29
On 2010 August 1, a global solar event was launched involving almost the entire Earth-facing side of the Sun. This event mainly consisted of a C3.2 flare, a polar crown filament eruption and two Earth...
An asteroseismic membership study of the red giants in three open clusters observed by Kepler: NGC6791, NGC6819, and NGC6811
asteroseismic membership study red giants clusters observed Kepler
2011/9/29
Studying star clusters offers significant advances in stellar astrophysics due to the combined power of having many stars with essentially the same distance, age, and initial composition. This makes c...
A Generalized Flux Function for Three-dimensional Magnetic Reconnection
Generalized Flux Function Three-dimensional Magnetic Reconnection
2011/10/18
The definition and measurement of magnetic reconnection in three-dimensional magnetic fields with multiple reconnection sites is a challenging problem, particularly in fields lacking null points. We p...
Variability in the CoRoT photometry of three hot O-type stars. HD 46223, HD 46150 and HD 46966

2011/9/27
The detection of pulsational frequencies in stellar photometry is required as input for asteroseismological modelling. The second short run (SRa02) of the CoRoT mission has provided photometric data o...

2011/1/11
Based on the diffusion-halo model for cosmic-ray (CR) propagation, including stochastic reacceleration due to collisions with hydromagnetic turbulence, we study the behavior of the electron component ...
