Extreme PeV accelerator associated with GRS 1915+105
Zhen Cao, F. Aharonian, Y. X. Bai +322
Microquasars, binary systems featuring relativistic jets, have emerged as sources for particle acceleration beyond PeV energies. We present a study of the broadband -ray emissi…
A sudden dramatic change and recovery of magneto-environment of a repeating fast radio burst
Y. Li, S. B. Zhang, Y. P. Yang +35
Fast radio bursts (FRBs) are millisecond-duration radio bursts with unidentified extra-galactic origin. Some FRBs exhibit mild magneto-ionic environmental variations, possibly attr…
Transient Large-Scale Anisotropy in TeV Cosmic Rays due to an Interplanetary Coronal Mass Ejection
Zhen Cao, F. Aharonian, Y. X. Bai +309
Large- or medium-scale cosmic ray anisotropy at TeV energies has not previously been confirmed to vary with time. Transient anisotropy changes have been observed below 150 GeV, esp…
Searching for radio pulsars in old open clusters from the Parkes archive
S. B. Zhang, J. J. Wei, X. Yang +7
Motivated by the discovery of a pulsar in the direction of the old open cluster NGC 6791, we conducted a search for radio pulsars in archival Parkes observations targeting similar…
A universal break in energy functions of three hyperactive repeating fast radio bursts
Q. Wu, F. Y. Wang, Z. Y. Zhao +16
Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances with a mysterious origin. Observations show that at least some FRBs are produced by mag…
