Statistics of VHE gamma-Rays in Temporal Association with Radio Giant Pulses from the Crab Pulsar

A dedicated search for an enhancement in the number of VHE gamma-rays correlated with the occurrence of radio GPs was carried out separately for the P1 and P2 phase ranges respectively. 99444 radio GPs have been detected in the radio data sample. Expand abstract.

Broad-band X-ray observations of four gamma-ray narrow-line Seyfert 1 galaxies

Narrow-line Seyfert 1 galaxies (NLS1s) is one of the few classes of active galactic nuclei (AGN) harboring powerful relativistic jets and detected in $\gamma$ rays. Expand abstract.
