Identification of the TeV Gamma-ray Source ARGO J2031+4157 with the Cygnus Cocoon
YBJ Collaboration, B. Bartoli, P. Bernardini +80
The extended TeV gamma-ray source ARGO J2031+4157 (or MGRO J2031+41) is positionally consistent with the Cygnus Cocoon discovered by -LAT at GeV energies in the Cygnus super…
Optical Monitoring of the Seyfert Galaxy NGC 4151 and Possible Periodicities in the Historical Light Curve
Di-Fu Guo, Shao-Ming Hu, Jun Tao +3
We report B, V, and R band CCD photometry of the Seyfert galaxy NGC 4151 obtained with the 1.0-m telescope at Weihai Observatory of Shandong University and the 1.56-m telescope at…
Long-term optical and radio variability of BL Lacertae
Y. C. Guo, S. M. Hu, C. Xu +6
Well-sampled optical and radio light curves of BL Lacertae in B, V, R, I bands and 4.8, 8.0, 14.5 GHz from 1968 to 2014 were presented in this paper. A possible yr…
Energy Spectrum of Cosmic Protons and Helium Nuclei by a Hybrid Measurement at 4300 m a.s.l
B. Bartoli, P. Bernardini, X. J. Bi +97
The energy spectrum of cosmic Hydrogen and Helium nuclei has been measured, below the so-called "knee", by using a hybrid experiment with a wide field-of-view Cherenkov telescope a…
