Effective Shielding of 10 GeV Cosmic Rays from Dense Molecular Clumps
Rui-zhi Yang, Guang-Xing Li, Emma de Oña Wilhelmi +3
The density of cosmic rays inside molecular clouds determines the ionization rate in the dense cores where stars form. It is also one of the drivers of astrochemistry leading to th…
Is Fermi 1544-0649 a misaligned blazar? discovering the jet structure with VLBI
Chengyu Shao, Xiaopeng Cheng, Tam Pak-Hin Thomas +8
Fermi J1544-0649 is a transient GeV source first detected during its GeV flares in 2017. Multi-wavelength observations during the flaring time demonstrate variability and spectral…
Spatially decomposed -ray features surrounding SNR Kes 79 & PSR J1853+0056
Xinbo He, Yudong Cui, Paul K. H. Yeung +3
There have been substantial improvements on Fermi Large Area Telescope (LAT) data and analysis tools since the last analysis on the mid-aged supernova remnant (SNR) Kes 79 (Auchett…
A multi-wavelength study of the gamma-ray binary candidate HESS J1832-093
Pak-Hin Thomas Tam, K. K. Lee, Yudong Cui +6
We investigate the nature of the unidentified very-high-energy (VHE) gamma-ray object, HESS J1832-093, in a multi-wavelength context. Based on X-ray variability and spectral index…
Is the SNR HESS J1731-347 colliding with molecular clouds?
Yudong Cui, Ruizhi Yang, Xinbo He +2
The supernova remnant (SNR) HESS J1731-347 is a young SNR which displays a non-thermal X-ray and TeV shell structure. A molecular cloud at a distance of 3.2 kpc is spatially coinci…
Leaked GeV CRs from a broken shell: Explaining 9 years Fermi-LAT data of SNR W28
Yudong Cui, Paul K. H. Yeung, P. H. Thomas Tam +1
Supernova remnant (SNR)\,W28 is well known for its classic hadronic scenario, in which the TeV cosmic rays (CRs) released at the early stage of this mid-aged SNR are illuminating n…
The hour-timescale GeV flares of PSR B1259-63 in 2017
Pak-Hin Thomas Tam, Xinbo He, Partha Sarathi Pal +1
GeV flares from PSR B1259-63/LS 2883 were seen starting around 30 days after the two periastron passages in 2010 and 2014. The flares are clearly delayed compared to the occurrence…
A general relativistic external Compton-scattering model for TeV emission from M87
Yu-Dong Cui, Ye-Fei Yuan, Yan-Rong Li +1
M87 is the first detected non-blazar extragalactic Tera-Electron-Volt (TeV) source with rapid variation and very flat spectrum in the TeV band. To explain the two-peaks in the spec…
