2018年 SPIE 空间望远镜和仪器：紫外线到伽马射线 会议
2017/11/27
Observation of the hot universe, from 105 K upward, has a vital impact on some of the most fundamental questions in astrophysics today. Hot plasmas, from the sun and stellar coronae to the cores of ga...

2017/3/30
A new citizen science project, led by astronomers at the University of Minnesota, is asking for help from the public to identify and categorize hundreds of thousands of ring patterns within images pro...
Galactic center's gamma rays unlikely to originate from dark matter,evidence shows
Galactic center gamma rays dark matter
2016/2/23
Bursts of gamma rays from the center of our galaxy are not likely to be signals of dark matter but rather other astrophysical phenomena such as fast-rotating stars called millisecond pulsars, accordin...
Consequences of the LHC Results in the Interpretation of gamma ray families and Giant EAS Data
the LHC Results the Interpretation
2011/1/13
The earliest results of CMS exhibit central pseudo rapidity densities larger than the predictions of the different models. Introducing on this basis new guidelines with larger multiplicities of secon...
Constraints on a hadronic model for unidentified off-plane galactic gamma-ray sources
hadronic model unidentified off-plane galactic gamma-ray sources
2011/1/10
Recently the H.E.S.S. collaboration announced the detection of an unidentified gamma-ray source with an off-set from the galactic plane of 3.5 degrees: HESS J1507-622. If the distance of the object is...
The Massive Pulsar PSR J1614-2230: Linking Quantum Chromodynamics, Gamma-ray Bursts, and Gravitational Wave Astronomy
The Massive Pulsar PSR J1614-2230 Linking Quantum Chromodynamics
2011/1/11
The recent measurement of the Shapiro delay in the radio pulsar PSR J1614-2230 yielded a mass of 1.97 +/- 0.04 M_sun, making it the most massive pulsar known to date. Its mass is high enough that, eve...
"Discrepant hardenings" in cosmic ray spectra: a first estimate of the effects on secondary antiproton and diffuse gamma-ray yields
Discrepant hardenings cosmic ray spectra the effects on secondary antiproton
2011/1/11
Recent data from CREAM seem to confirm early suggestions that primary cosmic ray spectra at few TeV/nucleon are harder than in the 10-100 GeV range. Also, helium and heavier nuclei spectra appear syst...
Optical Spectral Variability of the Very-High-Energy Gamma-Ray Blazar 1ES 1011+496
Optical Spectral Variability the Very-High-Energy Gamma-Ray Blazar 1ES 1011+496
2011/1/11
We present results of five years of optical (UBVRI) observations of the very-high-energy gamma-ray blazar 1ES 1011+496 at the MDM Observatory. We calibrated UBVRI magnitudes of five comparison stars i...
A Statistical Comparison of the Optical/UV and X-ray Afterglows of Gamma-Ray Bursts using the Swift Ultra-violet Optical and X-ray Telescopes
Statistical Comparison the Optical/UV X-ray
2011/1/13
We present the systematic analysis of the UVOT and XRT light curves for a sample of 26 Swift Gamma-Ray Bursts (GRBs). By comparing the optical/UV and X-ray light curves, we found that they are remarka...

2011/1/11
The emission process responsible for the so-called "prompt" emission of gamma-ray bursts is still unknown. A number of empirical models fitting the typical spectrum still lack a satisfactory interpret...

The small solar power sail demonstrator "IKAROS" is a Japanese engineering verification spacecraft launched by H-IIA rocket on May 21, 2010 at JAXA Tanegashima Space Center. IKAROS has a huge sail wit...
GEANT4 Simulations of Gamma-Ray Emission from Accelerated Particles in Solar Flares
Solar and Stellar Astrophysics (astro-ph.SR)

2010/3/9
Recent claims of a gamma-ray excess in the diffuse galactic emission detected by the Fermi Large Area Telescope with a morphology similar to the WMAP haze were based on the assumption that spatial tem...
